A cluster of this makeup/size isn't going to be all that great. Some people have suggested gigabit to connect the nodes together. This doesn't even come close to the speeds, unless you are putting ALOT of ports in each node. Someone already mentioned that you only want the computers a few hops away, so you are going to want alot of 20+ port hubs. This also won't do you any good, since hubs are still broadcast. You are going to need probably a large router to handle this. Your networking hw for this could easily make it over $1 million. After you do this, you will then have to find a new bus, since PCI simply isn't going to be fast enough to handle this. Your next problem is that the interprocessor bandwith just isn't very good on a x86 machine, and neither is memory access speed. To top it all off, you are going to have to find some way to cool everything.
I am assuming that the processors are Alphas, just because it is easier. You could seal all of the cases and run a non-conductive fluid through all of them. Also, it would be possible to simply connect the busses of all of these computers together with something that could handle upwards of 10-20 gigabits/s. You could do hard drives and memory that are directly accessed through this same bus. Unfortunatly, what I just described is a Cray, not a Beowulf cluster. ( something resembling a T3E, except the bus speed on those is 128 GB/s )
PC's are great machines, but they only scale to a certain point. Beowulf also has its own major limitations, such as a lack of distributed memory, and the fact that it is unable to run programs that weren't specifically compiled for it. The ultimate distributed solution would be able to distribute anything that had forks or threads ( although I don't want to imagine what kind of bandwidth would be required to handle a program forking up to 2048 instances )
Since microsoft has been denying that you can use this feature in word to track users, it will be interesting to see what they have to say now. Yeah, this was a "good" use, but there are also "good" uses for tapping everyone's phone lines. This isn't any better than the PIII problem, it's actually worse.
On another note, I don't remember another virus writer ever being arrested. I'm curious as to what they charge him with... Theft of computing resources?
I agree with almost everything said in the the two reviews.This movie was cool enough to almost make up for other movies such as "The Net". One thing that noone mentioned was the soundtrack, which was also better than expected. The cinematography was truly amazing in this movie, many of the scenes were done with 2 motion cameras and hundreds of still cameras so that they could pan around a stopped scene. I was also amazed to see Reeves not kill a movie. I don't usually like him as an actor, but he was awkward enough to work.
Even the martial arts were good ( I'm a second-degree black belt ), the fight director for this film has done scores of other movies, but I believe this was the first one not done in Asia.
Sci-Fi has been so bad lately, The Matrix is very much the exception. You won't be able to make it through without thinking over and over again, "Cool!"
This is the first license I have seen that requires the programmer to monitor a specific web site. It seems to be fairly close to the GPL though, it does require that source code be available for free along with any derived product.
It's nice to see yet another company going along with the open source concept. One does have to wonder though, did this really need another new license.
While ESR can be somewhat annoying at times, he has still done quite a bit. He is one of the few people that has pushed the open source movement into the mainstream, and attempted to make contacts with the corporate world. I mean, he IS open source. The question really is, who could take this over? Almost anyone who I could think of fails at least one of the qualifications set down by ESR.
It's going to take someone with guts to stick their neck out for a cause that is only popular in a relativly small circle.
I am noticing that my Icons at the moment don't match the current news ( yes, cleared all caches between me and/. ) Are your icons matching the filtering being done on the articles?
It looks like Slashdot may have taken down this site already. Bravo. I can't get their server to transfer more than part of the HTML headers on any of their pages. I'm glad I saw this before it died. Yeah, these guys would have done well to take a quick look at the Jargon file. It isn't like it is very hard to find.
I hope this is a joke. In the case that it isn't... this sounds really boring. If you're going to have a Pi day, make it a little more interesting with a showing of Pi, or music from the movie. whatever. This sounds cute for about the first 15 minutes before everyone falls asleep.
OK...OK... So I shouldn't have even told you I was bleeding... But I did see to it that that computer got what it had coming. Yes, I am the other person behind this useless destruction. And as a note, all useful parts were removed before destruction. These pictures really don't do it justice.
Since noone has actually posted it here, and several people have asked for it... Here is the announcement off of the linux-kernel mailing list. If you are interested in the mailing list check out http://www.tux.org/lkml/ Ok, you know the drill by now. This fixes:
- yes, people told me about the new and improved ksymoops. Much better, no need for C++, and this one actually seems to compile and work reliably. - ntfs fixes - the vfat thing _really_ works now - NFS fix for deleting files while writebacks active. - ppa/imm driver updated - minor mm balancing patches - Alan took the gauntlet and cleaned up some CONFIG_PROC_FS stuff.

just my $.02
will someone moderate down this spoiler? I just read it by accident...

Another one... Its telling me that there are 7 comments... I only see 3.

Cute that the article didn't even have him buying a PC from IBM... sounds like some old souped up RT or somehting.
