RMS isn't much better, if you take that view. Don't get me wrong, I think he's a good guy, and I admire him for standing up for his principles. Both ESR and RMS do this. And I think it's great that people can fight for that. I do agree that they should both hold back a little... they sound more like fanatics than developers.
What Linux needs is a spokesperson... someone that we can point to and say, "He speaks for us!" (Or she... doesn't matter to me) But, whether it be a good thing or a bad thing, the interests of the Linux "community" are too diverse to agree on one person.
I'm not going to defend piracy, but I should point out that many universities/colleges have a MANDATORY first year requirement of staying in the dorms. Even the one I graduated from still does this, despite the fact that they never have enough room for the new students.
In my experience, most anime downloads are of the fansub type... not that there aren't 5 zillion DBZ episodes pirated on Morpheus, but show me a subtitled Star Ocean EX collection, and I'll be the first in line to buy it. Until then, I'll have to rely on Morpheus and people who actually know Japanese.
And yes, I'm hoping to learn it myself and import... but that takes time. I'm working on it;) My point being that sometimes, it really IS the only way to watch a show.
Re:Building a mosix cluster
on
OpenMosix
·
· Score: 4, Informative
I don't have a link handy, as it's been a few months. I found it to be fairly simple to install... I had 4 PIII machines, set them all up on an internal network and nfs mounted a directory from the head. From there, it was a simple series of steps:
Unpack kernel sources.
Run the Mosix install script.
Did that on each node, then started the mosix service on each.
It worked like a charm for large computations, but had three flaws for normal use.
1) By default, it does not auto-migrate, which was pretty dumb. And getting it to auto-migrate was buried deep in the docs, though it could be guessed from reading up on locks. (echo 1 >/proc/self/lock, I think it was)
2) Migration only occurrs after a certain load average is maintained... if your job involves spawning multiple short-lived processes, like a large compile, it doesn't migrate anyway.
3) Network usage for migration was very heavy over Fast Ethernet.
There you have it. It's the last reason that MOSIX isn't used often in commercial clusters, but it seems well-suited for other distributed computing applications, and has some interesting features, especially for NOW configurations.
Unfortunately, no. I can't give too much information, since that is periferally involved in some of the things my company is doing, and with NDA's etc... We're going to have an Open Source version, though:)
I think he is planning on doing animations. I'm not in the visualization area, I'm a systems level guy, so I can't give you too much info on this.
I know a guy that clusters them to render scenes of 100 million+ polygons. And no, I'm not making this up, it is possible(well, sort of... you have to do reads from the AGP bus, over a Myrinet network, and that's unusual enough that he's still doing research) It may only be static scenes, but it's still impressive.
Oh my god... I nearly fell out of my chair when I remembered that scene!!! Need to dig out my Slayers tapes... or better yet, wait for payday and get the DVD collection:)
*sigh* Thanks a lot... more money down the drain;)
I still have frequent lockups and stalls with XP. Granted, this is due to a buggy video driver, but even without that, it's not exactly "there" yet. My Linux partition on the same machine NEVER goes down. And I'm running the video and sound drivers from CVS. XP is a HUGE step up from 9X(especially ME... that's on my laptop for work *shudder*) but to say it's as stable as Linux is laughable.
I'd trust it for light loads, or higher if I spent a LOT of time configuring it. But I don't have to worry too much, since my company uses Linux anyway:)
I'm proud to say that I bought all five of my Loki games. I was thoroughly impressed with the ports, and it's a pity they aren't sticking around. The best part was that they(usually) chose only the best to bring over, so us Linux users weren't stuck with mediocre games. Quake III, Railroad Tycoon II, Heroes III, Myth II, Heavy Gear II... these are the games I bought, and they're worthy of keeping installed. If I can find the money to buy these games on a shoestring student budget, why couldn't others?
Sorry for the rant... it's been a bad month, and I don't want to see Loki go.
The XP series have thermal diodes, so that comment isn't valid in this case. Besides, out of all the computers I have worked with(over 1000) I can think of only one that ran without a heatsink... and the guy forgot to put it on, it didn't fall off.
And before you make comments on what an idiot he was... you try building 200 systems in a row with no mistakes:)
That would be a good argument, except for one flaw: Not everyone downloads copyrighted content. I make a decent amount of money, and buy a LOT of DVDs each month. None form big name studios, since most of the stuff isn't worth watching. Mostly anime. But here's a summary of my Media directory, where I keep all my downloads. Hmm... looks like I have:
10 episodes of Star Ocean EX, fansubbed. If this were brought to the US, I'd buy the DVDs.
1 Episode Dragonball GT, fansubbed. This is being released, and I'll likely buy it. Maybe not. GT sucks, mostly.
Several clips from varios anime and movies, none more than 3 minutes long. Perfectly legal.
A load of fan-made, anime music videos. I don't know what the legality of these are, but most would agree that they're perfectly harmless.
oh! 4 MP3s!
- Opening to Xone of Enders... can I even buy that?
- Opening to Metal Gear Solid 2... that'd be a nice CD.
- A Linkin Park MP3 from an album I own... no comments on my taste, please.
- A Queen song from Highlander... which I own the soundtrack to.
And one piece of software, a Quake 3 mod. 90% of this stuff is very difficult to get elsewere, sometimes impossible(the Star Ocean episodes, in particular, since importing the tapes from Japan is impractical. I'd need a new VCR, and don't speak Japanese anyway)
West Virginia University also fields one, with 5 stations. As I recall, it's been around since about 1972, so this is obviously nothing new. I do know that breakdowns and errors are a little too common to completely ditch the bus system, but it seems to suffice for student(I'd estimate a 97% uptime). Given the age of the system, and that it was built when the technology was fairly new, I'm actually fairly impressed with it.
Yeah... all thos heat sinks jumping off the chips. When is Ford going to recall all those cars with gas tanks? Those things explode, you know... all they need is a little fire.
Heh... that's been my.sig since 99, and it's still mostly true... I use Linux at work and don't PROGRAM for Windows. Thanks for pointing out that it's a bit stale, though... guess I should look for another.
My Audigy hasn't caused a single crash on my SMP system. I think I even have LiveWare installed... well, at least I have some of their utilities. I do have crashes, but they're all due to the Radeon 8500 beta drivers(to be expected)
True.. though the Xeon isn't THAT much more expensive than a normal P4, oddly. And as to why do it cheaply... two words: Beowulf Cluster. Also, in my experience, dual P4 does not "smoke" the dual Athlon. Faster in certain matrix multiplies, etc. But only for situations using SSE2.
If you're looking for chaper Dual Xeons, it seems that they have a "bare bones" motherboard, but it's hard to find. The P4DCE, I think it was.
I prefer the Star Ocean series... a dream come true for the anal-must-get-everything-in-the-game players, without being insane(4 CDs in 12 hours?!? Who is that dedicated? See the FF9 FAQ about Excaliber 2 if you don't understand what I'm talking about)
Star Ocean was one of the more advanced SNES games which unfortunately didn't make it to the States... Star Ocean 2 is one of my favorite PSX games, and I'm eagerly awaiting a translation of the Game Boy version, and the upcoming SO3 for PS2.
If the P4 is such a good deal, meet me in this challenge: build a dual-processor P4 that isn't at least $500 more expensive than the dual Athlon. Bare bones dual-processor, the Athlons are a bit over $1000... you'll be paying at least $2000 for the dual P4. I know this, since I've built a number of each.
The point is, calling it "Hardware" RAID is deceptive, since all the "hardware" does is pass on the calculations in a format the CPU can understand. And yes, the performance of the FastTrack et. al. is excellent with modern processors, but if you're looking to eke out that extra bit of performance, a 4-channel Escalade is your only option in Linux, unless you want to spend ungodly amounts of money on SCSI drives. And as for the RAID 5 of the Escalade, I am well aware of the limitations. But we were talking about RAID 0+1, weren't we?
Wrong... the FastTrack series uses a BIOS implementation, true, but it offloads the striping calculations and such to the CPU. It's basically a BIOS trick that LOOKS like hardware RAID. For a true hardware RAID controller, you're looking at a few hundred even for IDE RAID, such as the Promise SuperTrack or, better yet, the 3ware Escalade series(which is supported in the 2.4 kernel series by default)
well, almost. At WVU, we basically take DOS, and slowly take over the various functions of DOS as the semester progresses. By the end of the semester we have a shell, a dispatcher(our OS is multiprogramming, unlike DOS), drivers for printer and serial port, and other such stuff. We talk about File Systems and memory management and virtual memory, but don't implement them(we use FAT, and the support routines to interface to our code are written for us).
The coding is done in C, and I don't think I've ever spent as much time in a programming class or learned more about software engineering in a semester.

Mine lists the true speed(Tiger MP).
Actually, I'm not sure if it lists it on bootup. But it definitely lists it in the BIOS Setup screen.
