IIRC, from the original '386 architechture forward, a segment can be marked as data or execute. For example, see this reference
I wonder why Intel is unable to use this functionality in conjunction with the current version of Windows to prevent introducing executable code via stack overflows?
Doesn't the other side of this sheet get really, really warm? The heat it's removing has to go somewhere doesn't it?
Can someone explain why this wouldn't make your car an oven? Most "thermoelectric" devices I've seen only have about a 10 degree differential from one side to another. Bringing a keg down to 32 degrees (F) in a car sounds like it would take a LOT of energy.
Pineapple on a lot of modification! Shared everything: in this, each disk is
connected to all the data. standard apps like SAP etc can be used in other ways
(you could run a web site off an Itanium 2), but the segment that Cray, SGI, HP
Alphaservers, etc. have traditionally dominated.
The segment that doesn't give a
shit about cooling, power consumption, or price-performance, but who just need
to break up data judiciously and spread acros s machines. Also adding a node will require re-partitioning of data. Mostly only custom apps which are fully aware
of your partitioning etc will be able to take advantage.
It is also likely cheaper than a similarly equipped Itanium 2 server would easily top $6,000.
But anyway, good game to Lawrence Livermore. I'll be curious to see if Apple has
another volley to fire before the top500 list closes for this round.
- "When you want to occasionally hand-tune code segments in assembler, etc."
Anyways, I'm not a fan of Intel lately, but the Itanium could have been a good choice.
ALSO: Don't forget that the Itanium 2 is $1398 per chip on Pricewatch, and a dual processor Xserve.
Just a little ahead of Apple when you look at terraflops/processor.
If I calculate right, they are claiming an Rmax of 19.94 teraflops with 4096 processors.
The Virginia Tech cluster for Apple had an Rmax of 10.28 teraflops with 2200 processors.
So, the Itaninum 2 delivered 4.8 gigaflops per processor, the G5 delivered 4.6 gigaflops per processor.
This seems like a pretty poor showing for Itanium 2, overall. It's a much hotter chip than the Opteron or the G5, so cooling and power costs are likely much higher than a comparable apple cluster. The Xserve G5 is also likely cheaper than a similarly equipped Itanium 2 server, given that the Itanium 2 is $1398 per chip on Pricewatch, and a dual processor Xserve G5 cluster node is $2,999 list. Even with 4 cpus in a single box, I think the Itanium 2 server would easily top $6,000.
But anyway, good game to Lawrence Livermore. I'll be curious to see if Apple has another volley to fire before the top500 list closes for this round.
No, according to the Bible, works ("living a good life" in your words) don't count, no matter how great and wonderful you think you're being. Faith, and only faith gets the job done.
No offense, bub, but you need to dump your Idol-worshipping religion and observe something where actions (and ONLY Actions!) matter. Consult your local Rabbi on how to convert!
They'd be ripe for infection if Macs were more than 2.5% of the installed user base (at best!)
Back in the early days, when viruses were spread on BBS and floppy, Mac viruses were a much worse problem than "IBM-PC / MS-DOS" viruses. Some of these early Mac viruses (circa 1987-1990) were so common that commercial software would not-infrequently ship with them!
Of course, Macs market share percentage has declined, so it's hard to get anything to spread if it's written for a Mac. However the insular user base could allow a very clever trojan/virus to spread to all Mac users and then, at a fixed date in the future, deploy the payload. There's nothing in Macintosh technology--despite the lies from the Mac heads--that prevents against this.
'I downloaded the file in the hope that perhaps Microsoft had released some sort of public beta.
Yeah, right! He deserved what he got!
This proves that Macs don't get attacked by trojans in email, etc, not because it's somehow more secure or "better" technology, but simply because
There's no technical reason why Macs can't be attacked as much as Windows computers are.
They can find other pimple-faced kids to play videogames on TV. Especially in LA, where "aspiring actors" are a dime a dozen.
No need to bring any of the boys and girls from the SF studio down to LA. In fact, they probably wouldn't last a week there. There's a reason they're living in SF and not LA.
What are we trying to do? Raise a new generation of pedophiles? I personally wouldn't trust my son or daughter near anyone teaching Java!
Why don't they base it on an open-standard language like C++ or C#, or a "academic" language like Smalltalk, Squeak, or MIX? That would be much better than supporting the pedophiles who support Java?
Apple comes out with a dual-G5 with fast everything, and y'all start skipping down the street with your iPods up your buttholes saying "It's a Thupercomputer! Itth fathster than a PEE-THEE! Tra-la-la"
So Microsoft, if the story is true, has set the bar high for their next OS, and you all are saying "What ever happened to 640K being enough."
and then you slit the binding off the notebook and run your notes through a sheet-feed scanner?

Don't y'all remember "USE THE FORCE LUKE"?
If we were making STAR WARS references (always on-topic), then this post was certainly dead-on.
Use the SOURCE, Luke!
Tech TV should have built and used a few of these to keep Comcast away!
Wait a minute! What type of perverted logic is this. If SOMEONE ELSE just pointed this out, then YOUR post is JUST as redundant.
I'm going to ask /. for a REFUND on my subsciption. I didn't pay good $$$ to be surrounded by idoiots and jerkoffs!
We better be careful, we don't want to start pissing of people in other universes. We're in enough trouble with *this* one!
I think I saw the "double-slit" experiment on a pr0n site the other day!

Now you can't say you have the fastest "Thupercomputer" any more! You've been beat by Intel and Linux!
No offense, bub, but you need to dump your Idol-worshipping religion and observe something where actions (and ONLY Actions!) matter. Consult your local Rabbi on how to convert!
(This was no joke! They really won't support anything other than Windows XP for desktops or FreeBSD (and 2003 Server) for servers.)
Sorry, Apple, but I can't accept your offer. You see, my IT department won't support Mac servers.

Let me explain /. (i.e, demented, twisted) logic to you:
If MICROSOFT does it, it's EVIL
If APPLE does it, it's GREAT!
Got it!?
Well, considering Sony INVENTED the portable stereo player, it's not clear to me who woke whom up.
A "Screen Savers" without Kevin Rose is like a Day without Sunshine! I can't imagine watching some LA "actor" portraying a Silicon Valley nerd.
I must admit it! I have a thing for Kevin Rose. Maybe Comcast can feature him in some adult programming?

Seriously though, this title is offensive to Italians, you insensitive clod!
