Buses and Interconnects: The Next Generation
mkarpinski writes "ExtremeTech has posted a nice overview of the next generation of peripheral buses and interconnects including PCI-X, InfiniBand, 3GIO, and HyperTransport. From the article, "All these future interconnects and buses have a few things in common. They use packet-based, point-to-point connections; in fact, InfiniBand implements a full switch fabric. They provide bandwidth in multiples of that offered by PCI. They decrease latency significantly, with HyperTransport and RapidIO showing the most dramatic decreases, crucial for their target communications and embedded markets. And all four strive to reduce pin counts in order to conserve power and system real estate." Open the floodgates!"
What is the killer application for these technologies? Seriously though it is largely irrelevant if you drop the best of the best video card on a AGP4x slot versus an AGP1x, because the extra-bandwidth largely isn't necessary. What would be the killer application that would encourage us to replace our architectures with it?
...On how long it will be before the chipset developer scene splits into equal parts toward their favorite standard. Also taking bets on how long it will take before we're all going to have to buy 6 different adapters just to ensure we can use the hardware we want.

"Many people still don't fully understand and cannot effectively differentiate InfiniBand from PCI-X from RapidIO, or 3GIO from HyperTransport, for example."
geez, what are you guys, a bunch of idiots? I can't *believe* that some people STILL don't fully understant inifiBand form PCI-X from RapidIO, or 3GIO! What is the world coming to?

...that only ONE of these standards actually goes mainstream and takes the place of PCI. This reminds me of the DVDR-W versus DVDR+W conflict that's going on right now. You've got multiple standards that are totally incompatible with each other, and yet neither of them has any true advantage over the other.
Hopefully one standard will emerge, so I can *safely* proceed with upgrading my PC hardware without fear of immeidate obsolescence.
Losers ride the bus.
If my memory serves (occasionally it does) PCI-X has been "on the drawing board" for, what?, the past 5 fricking years?
Quick with the acronyms, slow delivering anything useful...heck not delivered anything yet from what I've seen.
3GIO, Infiniband and Hypertransport...remains to be seen. But at least there is a 1 out of 3 something showing up and relieving these "low bandwidth blues".
Isn't Hypertransport supported by the AMA?
whoops, acronym abuse...Apple, Microsoft and AMD?
Seeing as Hypertransport is AMD's brain child.
We'll see, but it winds up being a matter of "the chips falling where they may", especially in the hands of motherboard makers, where they belong.
Whoever comes out with an actual working spec could say "Get on the bus, come ride with us" in a commercial and not be referring to city transit.
(can you tell I want to go home an hour early?)
If it is not on fire, it is a software problem.
Plus with server storage moving into the Terabytes and everyone goign broad band it will only be a matter of time before there is a need to handle huge gobs of info at teh same time.
RapidIO is in the PPC G5 roadmap and will be in moto's first g5-based chip. I've been drooling for some time now...

Even though we (myself included) always complain about all the "standards" there are, it really is a good thing in the long run. Even thought I hate having to deal with stuff like which keyboard to i need for this system (USB, PS2, Big DIN connector), it is good. I know the best usually wins. It's just like ISA vs. PCI vs. AGP, USB 2 vs. Firewire, SCSI vs. IDE, (yes, I know those are not apples vs. apples, but you get my point). Eventually, we just have to wait it out, and then buy whoemever the winner is. The unfortunate part is that the early adopters (a lot of slashdot readers) are the ones that pay the high price for new technology, but that's the way it goes.
However, if we look at trends in 5 to 10 year periods, we can clearly see what technology won the battle for existence and standards. The best technologo doesn't ALWAYS win (think Windows Media...), but more often than not, and that gives time to sort out the better from the good. Right now, though, we do live with a lot of different, competing standards that are quite frustrating.

going to help out developers? Im not familier with these specs, but is it going to say help the device driver writer any by providing an easier means to access device registers, I/O addresses/data and such? Are they trying to implement a standardized device api or somthing. If the answer is yes to any of these questions then im all for them duking it out and picking ONE of these as a replacement for pci. But if pc manufactures start spec wars again, i think im going to stick with current hardware.
I will bend your mind with my spoon
(pulling foot out of mouth...pheh, pheh)
PCI-X seems to exist, but looks something like AGP 4X to 6X in light of this comment:
At it's maximum 133 MHz frequency, a PCI-X bus only supports one slot, but allows segmenting using PCI-X to PCI-X bridging for additional slots.
AAAAAaarrrrrruuuuugggghhhh!!!
Am I losing (or loosing, either works) my grip on reality or was the whole point to have all your cards belong to us and on the same damn freq/speed/clock perhaps at the FSB rather than a seperate timing?
Heh, an auto manufacture that says you can have all the torque you want, but one wheel at a time.
Lovely.
If it is not on fire, it is a software problem.
This article misses one crucial standard: PCIX 2.0. While not highly publicized it has some key features that make it more likely to show up in high performance systems that 3GIO. The PCIX 2.0 standard is due to be finalized at about the same time as the 3GIO standard will.
One should not theorize before one has data. -Sherlock Holmes-
Rather than multiple competing standards for the *next generation* of devices, why won't someone devise a bus technology which won't be obsolete in two or three years? While PCI-X doubling the bandwidth to 1GB sounds great, with upcoming 10 Gb network adapters, you've ALREADY reached its limit WITHOUT ANY OTHER PERIPHERALS! Imagine what will happen when 100 Gb is standard!
In the mean time, how about using some proven technology now? Five years ago, SGI was using multiple crossbars on their workstations to improve throughput, reduce contention, and decrease latency.
Why can't something like this be implemented with the current PCI architecture?
Okay, PCI-X sounds neat, and backwards compatibility is a plus, but if you read the article it states that PCI-X will run at the lowest common denominator - if you have three 133MHz/64-bit devices (up to 1.06 G/sec transfer) and one 33MHz/32-bit PCI device you're stuck at 33MHz. Four PCI cards, four crossbars, and you can get any speed you damn well like on any slot. Otherwise, the current crop of PCI modems and low-speed network adapters will end up limiting this anyway!
The remaining protocols sounds nifty, but I don't see any performance specs. As hopeful as I am that *something* good will replace PCI, I'm going to be very disappointed if there are too many standards and vendors can't agree on something.

Why do hardware makers insist on using marketroid-designed names? I'm going to stay with PCI until somebody comes up with a new type of bus: the Magic Bus.
Every day, I put a request on the queue.
Ooh yeah, it's the MAGIC BUS!

... you can opt to use clock-forwarding and tapped delay lines to take care of synchronization).
Its of course the least ambitious of the lot, but at the same time the only one really suited for today's application. Deserialization and clock extraction at a couple of gigabits is damn hard to integrate with standard CMOS (you might argue unnecessary too
What seriously needs to be focused on is particle switching.
What is the difference between this stuff and what Cray & SGI did in the mid '90s? Same speeds, point to point (~ 6GB/s). I think the MSS on HPPI was large, but what are the other differences?
I was reading through the article, and one question kept coming to my mind. It's great that they are coming up with higher bw busses, but it seems it will only help for I/O. What about memory? I know we have the 266MHz (I think) DDR memory, but how much is that really helping? How will memory access be affected by all of this?
sigged out...
Light rail is the wave of the future.
...the intelligent switching of devices on the bus. Having a packet-switched bus controller is important (and I've worked on the design of an Infiniband controller so it can work), but even having the application passing parameters to the bus controller is important. For example, should a network card in a workstation take priority away from the video capture card?
Consequence to the capture card: dropped frames, necessitates recapture.
Consequence to the network card: dropped network packets.
Bandwidth is important, but again - the application must drive the necessity for the bandwidth. Intelligent switching and caching in addition to the increased bandwidth are necessary.
ALSO, one important point - architectures such as HyperTransport are essentially point-to-point, so you need multiple HyperTransport interfaces per switch IC - something that will drive the costs up. Hopefully low-speed devices can all be dropped on the 1394b or USB2.0 buses and then those can be handled through specialized south bridges on PCs, for example. For high-end network apps, obviously the switching of multiple buses leading to optical driver modules is basically the application itself.

When I read the title I was thinking on the level of logic gates (and, or, inverters, etc).
Me confused.
On that PPC roadmap, it claims the G5 will have "New bus topology/RapidIO Interconnect Architecture".
Does that mean it will use Rapid IO for communication between it's processor cores, or to talk to the North bridge?
Apple was one of the early members of the HyperTransport consortium... what does this say about the G5's motherboard architecture?
I'm picturing some kid from the Howdy Doody show banging his head into a wall (That coming from an oooold Mad Magazine issue :P )
Chao
They use packet-based, point-to-point connections
If the RIAA found out they were using P2P technology, they would be in serious trouble. The RIAA has graciously enlightened us all about how P2P is a tool of criminals and has no legitimate uses in this world. Oh the horror!
For every post, there is an equal and opposite re-post.
I'll stick my foot out and make some predictions regarding the various interconnection technologies for desktop and server machines.
PCI and PCI-X will be replaced by 3GIO as the predominant expansion bus.
Proprietary cpu-to-chip busses like Intel's Pentium 4 bus, AMD's EV6 bus or Motorola's MaxBus will, in the longer term, be eventually replaced by 3GIO for I/O (with the memory controller a part of the CPU). In the shorter term AMD and maybe the PowerPC camp will make CPUs with HyperTransport. An interesting possibility for PowerPC CPUs might be Motorola choosing to make PowerPC CPUs with a RapidIO bus for the embedded market and Intel choosing 3GIO (or perhaps HyperTransport).
Chip-to-chip interconnection will standardize around either HyperTransport or 3GIO depending on the flavor of CPU and expansion bus in the machine. It seems awkward to use HyperTransport to connect a 3GIO expansion bus, but it makes a lot of sense to use HyperTransport to connect a PCI expansion bus.
The MIPS and PowerPC camps will push RapidIO in the embedded market, but I foresee RapidIO eventually being displaced by 3GIO in mid-range applications like printers.
In the server-to-server and server-to-storage applications where IP networking is not appropriate FibreChannel will eventually be replaced by InfiniBand.
I just got a boner, but it turns out this isn't about Star Trek after all.
CRAP!
multiples of that offered by PCI
I sure hope that the multiples are real numbers greater than or equal to 2. I don't know if I could cope with (2+i) * PCI speed or -22/7 * PCI speed.

The
This is version 0.6 of a troll HOWTO, sort of a companion piece to jsm's excellent troll FAQ. As a draft, comments and criticism are always welcome, if not appreciated
Section 1 - Trolling techniques
There are techniques used by successful trolls to elicit the maximum amount of responses from unthinking
Timing
Because you're posting as an AC, your troll will generally be ignored in favour of posters using their accounts, and so getting in early is essential. A good guideline is to get into the first 20 posts, so that people reading the article will see the troll before it is swamped out. One way of increasing the speed with which you get your troll into play is to prepare them beforehand, and then quickly customise them for the current article. This is easier than it sounds since
Note that this is why Jon Katz stories are pretty worthless as trolling material - by the time you've found the article and prepared a troll there's already 50+ posts on it, most of them flaming Jon Katz anyway
Exposure
Once you've got your troll in, you need people to actually read it. You also want replies -
Accounts
An alternative to the time-honoured tradition of AC trolling is that of creating a "troll" account. This gives you the advantage of posting at 1 rather than 0, and slashbots are more likely to take you seriously, especially if you at least sound reasonable. If you do this, try to avoid posting stuff where it is obvious you're a troll under the account - post it anoymously instead - some slightly more canny readers actually check your user info before they reply. Not many though
The ultimate goal of the troll account is to secure the +1 bonus, which is currently received once you hit 26 points of Karma. To get there, employ the techniques of karma whoring that we see every day on
Layout
To get people reading it a troll needs to be easily readable. Make sure you break it down into easily digestible paragraphs, use HTML tags where appropriate (but always make sure you close them properly) and use whitespace appropriately.
Size
Generally a troll shouldn't be too short, otherwise it'll get lost in the crowd. A workable minimum is a couple of medium paragraphs. Conversely, it shouldn't be too long, or no-one will bother to read it. Keep it to a happy medium.
Spelling
Whilst spelling is important if you want the troll to be taken "seriously", key spelling mistakes can draw out the spelling zealots, especially if you mis-spell the name of a venerated
Subject
The subject line needs to draw attention to your post without making it obvious that it is a troll. A simple statement of the main point of your argument can work here.
Style
Once you realise that most moderators don't bother to read past the first paragraph or two, you can use this fact to craft trolls that can be moderated up as "Insightful" (note that I mean this in the
Linking
As we all know, a post with links is considered "informative" by the
Feeding
The ideal troll requires no feeding - it runs on its own, generating flamewars between clueless
Know your audience
Always keep in mind the kind of things advocated on
Arrogance
Be arrogant. You, as a troll, know that you're right. No other explanation could exist. The wronger the "fact", the more assertively you should state it. Make it clear that you are better than everyone else - you know the truth and they are just too stupid to realise it. Use plenty of sarcasm, and use "quotes" to show it to people too dumb to realise.
Offensiveness
Being offensive in your initial troll can be counter-productive - it causes moderators to mark you down as flamebait in general. But if you're feeding, then you can get away with calling
Indifference
Great for articles with a political or social bent, this kind of troll expresses complete indifference to the topic at hand, wondering who on Earth cares about it. An alternative method is to say that the topic only concerns a certain group of people - criminals, idiots, hackers (always use this instead of crackers) or whatever group you want to offend.
Sympathy
Appear to take the same stance as the people you're trying to troll - claim you're as much a fan of Linux as the next man, but... This way you can make all kinds of claims in the sure knowledge that you actually know what you're talking about. A great phrase to use here is "In my experience". Remember to act like all the things you're pointing out are unfortunate but true.
The common touch
Always accuse
The 31337 touch
The opposite of the above. Claim that technology or whatever is only for the elite of society and that any attempt to open it up for everyone is wrong, an attack on intellectualism and possibly even dangerous. If people were meant to understand these things then they would, and it's their fault if they're too stupid to learn.
Contradiction
Never be afraid to contradict yourself, even in the space of a single sentence. The phrases "I am a top programmer who codes in VB" or "I am a supporter of open source who uses NT at work and 95 at home" will be sure to get a response from some weenie smugly pointing out the contradiction. Confuse the issue more by engaging in contradiction when you are feeding - this will confuse
Clues
If you're feeling brave, give the reader clues that this is an obvious troll. The classic example here is dmg's stock phrase "I am often accused of trolling (whatever that is)", but also feel free to use phrases like "I have not read the article, and I don't know much about XYZ but I feel I must comment". If anyone responds to a troll with these kinds of clues in it, feel free to bask in the glow of knee-jerk
Denial
If you're unlucky someone will accuse you of being a troll (surely not!) and try and ruin it for you. If you don't want it all to end there, then be sure to counter it by accusing them of being small-minded and petty, saying that it's easier for them to say it's a troll than to accept that people have different opinions. Be sure to say this in the subject line, especially if their subject was the infamous "YHBT. YHL. HAND."
Claiming credit
Given that
As for when to post it, that's a matter of opinion really. You can either post it straight away or leave it will after people start biting. Remember that the troll forum is also frequented by non-trolls, and sometimes you may get a self-declared "troll-buster" try and expose you. But remember,
There is no real current forum at the moment thanks to various spammers hitting the sids, but try trolltalk, the original troll sid started by 80md and osm way back in the day. Generally all postings are done there as an AC, with your name at the end of the post. Include a link to the troll somewhere in the text, which ideally will be directly to the post and its replies - click on the #XX link in the thread to get there.
Ending the troll
Sometimes you just get bored with a troll, or people start posting genuinely thoughtful stuff in reply (it does happen). When this happens it might be time to own up to the troll with a helpful "YHBT. YHL. HAND." post. Sometimes people will carry on a discussion of the issue, and if you're really lucky (and it was a great troll) they will completely fail to believe you and carry on arguing. If that happens, pat yourself on the back for writing a great troll
The cheap $3 crack
Finally, when all else fails and your troll gets moderated down to (-1, Troll) within ten seconds of you posting it, the only honourable thing to do is to accuse the moderators of smoking the cheap $3 crack (again) and give up
Section 2 - Types of troll
The Maniac
Probably the most popular kind of troll, the Maniac holds an opinion on something, and won't budge from that opinion no matter what evidence to the contrary is presented. If challenged, the Maniac will simply get more and more agitated and abusive, deriding his opponents as "idiots", "wrong-thinking", "dangerous" and "subversive". Generally the Maniac takes a position that opposes the prevalent
Maniacs can be crafted for practically every article
Here are some fruitful avenues to explore:
The Right-Wing Maniac
Always popular, the right-wing maniac (RWM) is a God-fearing, gun-toting, flag-waving American, and proud of it. They don't care about the rest of the world, unless it's to "prove" that America is better than everything else, and they cannot stand liberal whining over civil rights. They hate the moral decay of America and want it to revert into a nation of heterosexual, Christian whites like it was meant to be. Woe betide anyone that dares to suggest otherwise.
Religion
There are two ways to approach this kind of maniac. The harder to pull off is the militant atheist, but this is quite common amongst
Ideology
Pick a philosophy, any philosophy. This troll is a troll with a cause - they have found some kind of ideological truth, and are out to expose every other philosophy as a sham. Whether it be libertarianism, objectivism, communism or capitalism, this troll will point out the obvious "flaws" in any other philosophies, whilst spouting dogma about their own. And the best thing is - you don't even need to know that much about what you're spouting - making doctrinaire mistakes will get both sides of the argument flaming you, adding to the fun.
Software
This is an old favourite and crops up in many forms, covering the gamut from OS maniacs (Linux zealots, MS-apologists or embittered BSD fanatics), language maniacs (Pascal vs. C, C vs. C++, C++ vs. Java, Perl vs. Python, VB vs. everything), application maniacs(GIMP vs. Photoshop, Netscape vs. IE, vi vs. emacs) and also includes people who complain about how technology should only be for the 31337 hackers.
Guns
Americans love their guns, and will always fight passionately for their Constitutionally guarenteed rights to bear arms and shoot people. Even the slightest hint of criticism of this will bring down the wrath of a thousand and one enraged gun-owners on you, so it's always a great point to work into a troll
The Expert
The Expert is someone who is "savvy" in their particular field, and is perfectly willing to give their opinion on any topic even vauguely related to their field. The Expert is most likely to be from a field which
Some possible angles to exploit:
Industry knowledge
The expert knows the computing industry from the inside - as a long-term pro, they can dispense knowledge knowing that they can "speak for the industry". Their smug self-satisfaction is bound to annoy, as is any suggestion that things aren't the way that
Helpful hints
With their tech-savvy (or law-savvy or whatever) experience, the expert is obviously the best person to point out what's wrong with things or to give out useful "factual" information. In fact this probably works best with lawyer trolls - for all that
Offtopic Trolls
Not really a "troll" in the strict Jargon File sense of the word, but they certainly should be included here
Offtopic trolls, like any other, come in almost as many colours as an iMac, but generally not as cute. But then again, a good offtopic "troll" can affect more people than a repulsive little gumdrop on your desk, because you need to have someone SEE your desk before they can react. Simple? Moreso than even my overblown prose could indicate. Some basic examples:
The serial troll
Write a story. Keep expanding it. It doesn't matter what article you post it under, so long as it's high up. If you want people to recognize you, pick a couple themes or symbols, and carry them on throughout the story. Other alternatives include back linking or including the entire story, but adding more each time. Be funny if you want. Or if you don't feel like being funny, just be really weird. Someone will react.
The random troll
This has nothing to do with anything. Be it a stream of consciousness rant, or a description of the corner of your desk. Another favorite is a monologue, read as if spoken from any one given entity to another. The more outlandish, the better (a pair of socks talking to a mousepad, for example). If you really wanted to be artsy, work in an actual metaphor or legitimate meaning behind it, but it's not necessary.
The vaguely related troll
Start out with a comment about the article. Have a definite opinion of it. Then, after a little while, disintegrate into randomness. All roads eventually can eventually lead to cheese (yum), Natalie Portman, cannibalism, toasters, squirrels, futons, you name it. All it takes is a little bit of creativity. Oh, and feel free to use other trolls' motifs. Open source and all that
General tips:
If it's funny for a fleeting moment, then it's worth posting.
Puns. Puns are only less vile than mimes, but it's hard to mime on
Obscure cultural references and injokes are always good. SOMEONE will get them eventually.
Several drafts of a serial or random post are common, but true elegance is being able to come up with something on the spot that still makes the top 40 posts (on a post-heavy article)

Kelly
had
just
finished the last summer cheerleading practice.She was the first
girl in ten years to make the squad their freshman year. Several of the other
cheerleaders were upset. Kelly wasn't concerned about their thoughts. She shyed
away from others and had very few friends. She didn't believe in the clicks
people got into. Kelly is one of the prettiest girls in school. Shoulder length
reddish blonde hair, acute face with a small button nose, and always smiled.
Breasts the size of small grapefruits with nipples same size as quarters. Flat
slightly sculptured belly, slender waist, narrow hips, small plump butt and
perfectly shaped legs. All wrapped into a 5'4" 115pds frame.
After showering Kelly dried herself, as she went to her locker. She noticed four
girls across from her locker talking and snickering. Kelly ignored them. After
slipping her cotton bikini pantys on, she grabbed her bra. Somebody had cut the
straps. There was no way she'd be able to wear it now. She turned around to
confront the now, laughing girls. They quickly walked out of the lockeroom.
Kelly put on her low cut tank top, and shorts. After throwing her stuff into her
bag, she headed out. Her breasts stood just as if she had a bra on. Her breasts
firmly jiggled as she walked to the bus stop. Kelly was headed downtown to the
library first. Then to a movie.
Kelly had noticed lately that boys as well as men were looking her over as she
walked by. Today more so than ever. After she got off the bus downtown. She went
to walking the 4 blocks to the library. When a old black man walked out of a
alley. Hey there. Where you headed? (shyly and quietly) Oh, hi. I'm going to
have lunch with my dad. Kelly walked a little faster. She didn't notice that the
old black man was following her. Kelly went into the library and looked over a
couple of books untill it was time to go to the movie. She looked up. Over a few
tables was the old black man. Since she had noticed men looking her way. Kelly
was starting to become a tease. So, she walked his way to put the books away.
She knew he wouldn't do anything in public place. When she was in front of him.
She dropped the books. Bending over to pick them up. (without bending her knees)
Her tank top layed so the old black man could get a good look at her white
breasts. The old black man's mouth dropped open. Oh! Excuse me. (acting as it
was an acident)
Kelly headed to the movie. Which was a couple of blocks away. She loved the
reaction she had got from the old man. The movie Kelly wanted to see was sold
out. She wanted to see a movie. So, she got a ticket to another. Then she saw
that another was starting and it was rated R and nobody was around. She went on
in. Hardly anybody was there. Kelly sat towards the back . The movie started.
When a nude scene started someone came and sat by her. She didn't even pay any
mind. She in awe of what was on the screen. This was her first R movie. There on
the screen was a black slave climbing on top of his master's white wife to have
sex. Kelly liked the sight of the slave's black skin on the white woman's body.
Kelly didn't even realize the person beside her had placed their hand onto her
knee.
But, when he moved his huge hand upto her thigh. Kelly regained her awareness.
She turned. It was the old black man. She tried to push his hand away. He just
leaned over and kissed her neck. He kissed his way down to the tops of her white
breasts. As he moved his hand upto her shorts. He kissed the tops of her breasts
as he rubbed her crotch. He then unbuttoned and unzipped her shorts. Even though
she liked the sight of his black face to her white chest area. She knew she had
to do something before he got any further. She thought to herself (that she
shouldn't have teased this old man) As the old black man started pulling at the
young white girl's shorts. Stop. Or I'll scream. At this time an usher was
making his rounds. Kelly got up to leave. The usher stopped her. your not old
enough to see this movie. I know. I came into the wrong movie by acident. Kelly
left and went home.
It had been several weeks since the incident with the old black man. School had
started. Pro football season had started the week before, and Kelly's school was
going to have their first game tomorrow morning. Today they were having a pep
rally at the end of the school day. Kelly stopped over Stacy's house for awhile.
It was about 6:00p.m. Kelly hurried home to help set up things for her dad's
party. Every month her dad and some of his friends would get together and have a
few drinks and discuss sports. This was her dad's turn to have it at his house.
When she got home. Her dad told Kelly that her mother had went out with aunt Mae
and that she'd be out late. Kelly helped her dad set things up. Most of the guys
were there. Kelly fixed herself something to eat and took it to her room. She
turned on the stereo as she ate.
It was about 8:15 now and Kelly decided she'd take swim as it was unseasonabley
warm tonight. Kelly danced around to the music as she got her bikini out.
Without thinking she took her top and bra off. She was in front of the window
and hadn't pulled the blinds down. She looked outside and noticed Mr. Turner
looking up at her. Mr.Turner was retired runningback from the local pro team. He
was black very muscular. He stood about 6 feet tall and weighed around 235
pounds. Kelly was so embarassed. She hurried away from the window and put on her
bikini. She thought about not swimming. But, after a half hour she went on down
to swim. As she tried to sneak by the rec room. Mr. Turner walked out and almost
bumped into her. Oh! Hi. Didn't mean to run you down. Kelly couldn't even speak.
By the way. I didn't mean to stare earlier. It isn't everyday you see such
beauty. That's ok. (very quietly) As she went onto swim.
Kelly swam and relaxed poolside for a couple hours. She went on upto the
bathroom and took a shower. Dried herself. Then, slipped on a robe. She went
across the hall to her bedroom. As Kelly entered her room she looked to see who
was coming up the stairs. It was Mr. Turner. May I use the restroom. Sure. Kelly
pushed at the door. The door sounded like it closed. But, it came open slightly.
Kelly saw Mr. Hicks looking through his upstairs window towards her. He must be
around 73 years old. Kelly turned on the radio and started dancing. Her robe
came open. Mr. Hicks just stared as she danced. Kelly turned off the overhead
light after turning a lamp on. She thought to her self. She'd realy give
Mr.Hicks a surprise. She slipped her robe off. Exposing her totaly naked body to
him. After all he was in his house and to old to do anything. She danced around
for a few more seconds. Then she layed down on her bed. Mr.Hicks still had view
of her. Kelly was turning into a real tease and was liking it. She rolled over
onto her belly, so that Mr.Hicks would get a good look at her butt.
She heard the bathroom door open. She glanced at a mirror across the room, and
noticed her door was open slightly. She thought about getting up and closing it.
But it was to late. Mr.Turner was in the hallway next to her doorway. Kelly
acted to be asleep. After a few seconds she heard the door close. Kelly figured
that he pulled the door closed. But, when she heard some movement. She became
terrified. She kept her eyes shut as if she was sleeping. She then felt
Mr.Turner run his hand up the back of her white thigh. Kelly trembled as he
caressed her young white buns. She instantly felt herself getting wet inside.
Mr.Turner kissed her white butt. Kelly liked this but knew it was wrong. She
turned over onto her back. Don't!
Then she saw him. Totaly naked huge black man. Huge biceps, a very muscular
chest, ripple tummy. Kelly let out a quiet gasp as she noticed his huge erect
penis. It must be 11inches long and realy fat. She couldn't get her eyes off of
his huge black monstercock. Mr.Turner walked upto her face. Suck on it. No! as
she thought ( that would be gross) He rubbed his black cock across her lips a
couple times. He then went to the foot of the bed and knelt down. He kissed the
young white girl's thighs working his way up. Don't! Stop! I'll scream. As
squeezed her legs together. He kissed her blonde pubic hair, then lower belly.
Kelly became speachless as he kissed white belly and licked at her bellybutton.
Mr.Turner wasn't going to take a no for an answer at this point. He kissed his
way to her teenage white breasts. He kissed and sucked at her nipples at the
same time ran his hand to her young pussy.
Kelly let out a moan, as he inserted his finger inside her. She tried to push
him away. Even though she was enjoying what he was doing. Kelly knew this was
bad and besides he would most likely rip her in half. Mr.Turner rubbed at her
teenage pussy for moment to lubricate the outside of her pussylips. Mr.Turner
climbed onto the bed to mount her little white body. Kelly held her legs
together. Please don't It will hurt me. It only will hurt for a moment. Ohhh! As
Mr.Turner rubbed his huge black cock up and down her little pussy. He pushed
forward. No penetration. He gave big shove forward. Still no penetration of the
little white girl's pussy. He pushed again and finaly managed to get his
cockhead inside her. Kelly tightened up. He pushed a little deeper. She felt his
huge black cock press against her hyman. She knew that one more push would pop
her cherry. Just as he drew back. A knock at the door. Kelly! Kelly! Are you
awake. As the door opened. Mr.Turner jumped off the side of the bed.
Hi dear. Mmmom! Yes. Are you ok? ya. Dad, said you'd be late. The movie was sold
out. So, I came home early. Are you sure? That you are ok. Yes. Just tired. I've
told you to pull the blinds down. You are old enough now that guys will love to
see you dress and undress. You sure seem nervouse. Is there anything wrong? No
mom! Well, you look flush and sweaty. I'll get the thermetor. No. That's ok. I'm
alright. Ok. Call for me if you need me. Goodnight. Goodnight mom. Kelly was
trembleing. Mr.Turner jumped up and dressed and quietly went back downstairs
where there were still a few men gathered having their last drink. Kelly finaly
fell asleep a couple hours later. But, within another hour she woke up from a
bad dream. Her mother rushed in and comforted her. Kelly couldn't tell her
mother that she dreamed about being raped by twelve black men.
After this Kelly quit teasing men for a couple weeks. She started slowly once
more. She would mostly like old black men. She would go without a bra and leave
a button undone then lean over in front of them. During the holiday vacation.
When her parents were at work. Kelly even went totaly naked. Except a long
winter coat. She rode the public bus all the way downtown. She aboat croaked
when an old black man sat beside her. They talked awhile. He was headed to work.
He was going to retire in the spring, after 40 years of service. When he looked
the other way. Kelly undid the top button of her coat. Which exposed just a
little of the tops of her white breasts. Your a very pretty young lady. You need
to be careful. Someone may try to have their way with you. I can take care of
myself. Here's my stop. Take care.
Kelly felt ashamed. She stopped such things. Untill the last day of school. She
had worn her white blouse and plaid skirt.(the catholic school girl look) She
decided to walk home since it was very nice day out and school let out early.
She was walking through the park. She was nearing the walk bridge across the
creek. She heard some voices coming from under the car bridge nearby. There were
three black hobos. There was nobody else in sight. They were washing theirselves
in the creek. She starred at them. They only had their pants on. But, she liked
the sight o their black chests. Kelly also knew that they would most likely see
her cross the walkway. She was realy excited. After a moment she slipped her bra
then pantys off and put them in her backpack. This excited her. Even though they
were to far away to notice. She only had two blocks to go to get home from the
park. When she walked across the walkway. The men whistled and yelled to her.
They were close enough to see that she was a pretty girl. Kelly liked this but
ignored them. But, then she noticed they were following her. She picked up her
pace. A short distance from the street. They caught her. One of the black hobos
grabbed her. Turned her around. Man! We're goin to have a good time today. As he
saw her quarter sized pink nipples poking through her blouse. Then a cop drove
by. Then backed up. The men ran off. Mam! Were they bothering you? As the cop
walked upto her. No sir. He was a tall black man in his fortys. He took a double
take when he noticed her pirky breasts through her blouse. You need to watch how
you dress. Your asking for trouble.
That night she dreamed of Mr.Turner fucking her. She woke up in a sweat. She was
showering when her parents yelled in at her. Honey! We're headed to work early.
Kelly wondered more and more what it would feel like to be fucked by a black
man. Mr.Turner was very gentle with her. She couldn't believe how close she came
to being fucked. Kelly thought to herself-(I know it's wrong. But, I'm going to
find out today) She put on her bikini pantys then bra and her summer sundress.
After slipping on shoes she went downtown on the bus. Remembering the first
experience with an old black man. She walked towards the alley where she first
saw him. It was almost 10:00a.m. Ahead was a tall old black man. It might even
be the same man. Kelly acted as if she didn't notice him. She walked as if going
to the library. Hey baby! Don't you say hi to your friends? So, she knew he was
the same man and he remembered her. Oh. Hi. (acting not to be interested) Hey!
You want a puppy. (Knowing this was a ploy) (Even though she was scared-she was
going through with her plan) Sure! Where is it? Down here. In a box. Directing
her to the alley. Kelly nervousely followed. I sleep here and this puppy came
upto me and had no tags. A third of the way through the alley. There were stacks
of large cardboard boxes with blankets on them. There were five other old black
men laying on their blankets. Untill they seen her. Kelly started to leave. Not
soon enough. They surrounded her.
Don't I'll scream! One of the black men pulled out a knife. No you won't.
Unless! Kelly stood there while the black men fondled her. Two of them fondled
her breasts and two others played with her firm butt. One watched the street as
one of the black men unzipped her sundress and slipped the straps off of her
shoulders. Her dress fell to her ankles. Please! Don't hurt me. The man with the
knife walked upto her. Not saying a word. Cut the right strap of her bra. With
the other black men laughing he cut the left strap. Starring into her eyes he
ran the knife across the tops of her breasts. Then suddenly cut her bra in half.
Kelly's bra fell to the ground. Exposing her firm white breasts to the old black
bums. They all got quiet. Starring at the young white girl. The black man put
the knife up. Then with two hands grabbed her pantys and ripped them from her
petite teenage body. Kelly felt herself getting wet. Even though she was
terrified. Here she was a virgin about to be raped by six old black men in an
alley downtown. She didn't even know if they would kill her or not.
Kelly just watched as the man in front of her dropped his pants and undershorts.
He was black as midnight. His cock was hard pointing towards her. It was smaller
than Mr.Turner's. But, Kelly didn't see how it would fit into her. Kelly shaked
like a leaf and tears started to run down her face. The black man's cock pressed
against her belly as he stepped closer. He shoved her down onto a blanket. He
knelt down and pushed her legs apart. She was to scared to fight back. She
looked to the side as he mounted her. She noticed that the other men's dicks
were larger and fatter. He whispered to her I'm the nice one. The others would
just ram it inside you. He rubbed his black cock up and down her blonde pussy 4
or 5 times to slicken her up. He then pushed forward. Without sucess. Then
another, and another. Your one tight chick. One more huge shove forward and
Kelly felt his cockhead push inside her. Then another push and he was touching
her hyman. He pulled back. Then with a smile gave a quick shove forward. Kelly
screamed out in pain as his black dick ripped through her hyman.
The black man took pleasure at the painful look on her face. Your just a spoiled
white brat. As he slammed all 8 inches of his cock into her. Blood ran down her
butt. He squeezed her white tits so hard she thought that they would pop. She
felt his hairy black balls slamming against her white butt. The other black bums
were urging him to hurry. They wanted their turn. The pain subsided after a
couple minutes or so and Kelly was starting to enjoy the fucking she was
getting. She wrapped her legs across the backs of his. Kelly let out moans of
delight as the black man pounded his cock into her white pussy. She was about to
climax when she felt the man cum inside her. With one more lunge forward. He
pulled out of her. Who's next. She's a fine piece.
The next black hobo ordered her to her hands and knees. Like a dog you know.
After penetrating the young white girl from behind another got infront to force
her to suck him. She learned quick how to suck. Kelly first thought it was gross
to have a man's dick inside her mouth. After a couple minutes she even started
enjoying cocksucking. The man behind her fucked her as hard and fast as he
could. Making her buns and tits bounce around. She felt herself building to a
climax again. This time she squeeled in delight as she climaxed and felt the
black man cum inside her pussy. The old black man in front was cumming into her
mouth as the man behind pulled his black cock out and squirted a couple times
across her butt. The two black men quickly stepped away from the petite white
girl. When another layed beside her and directed her on top of him.
Kelly sat on his 12 inch black snake. She let out a gasp in dispair as the last
4 inches went inside her. It was uncomfortable as he fucked her. But, after a
moment it felt good being stretched this far. She figured he must have the
biggest dick in the world. To her surprise one of remaining black men knelt
behind her. He pushed her forward. He guided his 10inch black cock to her white
butt. He gave a hard continued push. Kelly screamed and tears appeared again as
she felt like she was being ripped in half. Without hesitation the black men
fucked her hard and unmerciful. One in her white ass and the other in her blonde
pussy. Even though it hurt after a few minutes of being double fucked. Kelly
yelled out in another orgasm. As the black man inside her butt squirted streams
and streams of cum inside her. Then the last black man traded places with the
man that was buttfucking her.
As he started buttfucking the teenage white girl. He yelled out. Hey! we're a
oreo cookie. Kelly was getting exhausted and was going limp. It felt like she
would pass out. Then she orgasmed again. After she came off of her third orgasm,
the man pumped her white ass full of his black seed. He quickly withdrew from
her as the man under her. Rolled over on top of her. He went to fucking his
black 12 inch pole in and out of her as fast as he could. He sucked on her white
breast. When he started cumming inside her he bit down. Kelly let out a yelp.
This didn't stop her from climaxing again, for the fourth time. The man stood
up. She was exhausted and just layed there. To her amazement they were still
standing around naked. We want you to meet Bubba.
Kelly was amazed when she saw Bubba. He was about 50yrs.old 6ft.6in. tall
220pds. His cock must be around 14 inches long. As he mounted Kelly's little
white body. He told her that he was going to fuck her brains out. It looked like
a black monster mounting a little white doll. He entered her slowly. Even though
she had been reamed out several times. It was slow going for him to get his
black cock into her. After getting 10 inches inside her white pussy. He started
fucking her hard. After a few minutes his huge black balls were smacking against
her white butt cheeks. Kelly orgasmed first. Then she felt him shoot a couple of
squirts of cum inside her pussy. He pulled his huge black cock out of her and
finished cumming all over her flat white belly. After he stepped back. She was
surrounded by the other six black men. They jirked theirselves off all over her.
She was drenched in cum. Her hair and face was covered with cum. Her white
breasts, belly, pubic hair, pussy, and butt was also was covered with cum. She
thought to herself I can't move. She figured that she was about to pass out with
exhaustion.
Kelly just layed there naked and covered with cum. The black men were dressed.
When she saw reflections of flashing lights. The black men had went to the
entrance of the alley. Kelly heard them talking to what seemed like police
officers. She slowly got up and peeked around the corner. It was the police. She
grabbed her sundress. As she walked out the otherside of the alley she slipped
on the dress. Her shoes had fallen off during all the fucking. Her breasts,
pussy, and butt ached from the pounding and stretching. She was drenched in cum
which was starting to dry on her now. No place to clean up. Oops. Excuse me. She
bumped into a lady. Are you ok. Yeh! Sure. Kelly walked three block as everyone
starred at her. Since she was such a mess. People kept asking if she was ok. She
got home on the bus. She threw her sundress in the washer, showered. Redressed
and fell asleep on the coach.

Woohoo InfiniBand. Finally small companies can build clusters that can compete with multi-million dollar SGI super systems. Beowulf clusters using Ethernet interconnects are nothing compared to a system with memory bridge level hardware interconnects. Current Linux clusters are often based around Ethernet which is very slow and has a high overhead when you want to put it to the use of letting processes on different machines talk to one another. Big Beowulf clusters have been shown to work well on embarrassingly parallel computational problems (key cracking, some types of CFD, and packet analisys like SETI@Home) but aren't really up to snuff with truely high end super computers without much faster interconnects. Some clusters (I think Microway and a few others) are built using Myrinet interconnects which are faster and actually provide the sort of connections big clusters need. Even using Myrinet you end up with alot of scalability problems because you only get your max throughput when transfering very large blocks of data to the same host. Having a Northbridge based interconnect (rather than something like a Myrinet card which is connecting to the PCI bus which in turn hooks to the Southbridge) is a very good way to speed up clustered systems. IBM, Sun, and SGI learned this a long time ago which is why they use high speed interconnects between individual boxes rather than trying to overextend network protocols.
