Exactly, I believe in life on other planets, but I didn't believe in this one for one second. And I'm very happy with Earth-made life. Why fabricate some silly far flung theory around a Martian rock... Beats me.
What's this nonsense about 2D? Well, in my world a dual layer would be 3D. Why insist on that this is new? It's better, yes, but it's essentially only more layers.
My interpretation, the Cray manages to produce a similar Rmax with four times fewer CPU:s thanks to their better bandwidth (as indicated by the higher Nmax). Is that a correct interpretation?
Comparing the Rmax and Nmax values it seems that the list would look quite different if sorted on Nmax instead of Rmax. Can someone explain in plain English the difference, as I didn't understand their explanation. Thanks!:)
As some parent noted, there wasn't as much competition back then. Now they had Micosoft's Xbox 350 to compete with. Maybe they hype[rventilate] some extra with a 600 lb gorilla next to them.
Researchers in the parallel processing community have been using Amdahl's Law and Gustafson's Law to obtain estimated speedups as measures of parallel program potential. In 1967, Amdahl's Law was used as an argument against massively parallel processing. Since 1988 Gustafson's Law has been used to justify massively parallel processing (MPP). Interestingly, a careful analysis reveals that these two laws are in fact identical. The well publicized arguments were resulted from misunderstandings of the nature of both laws.
This paper establishes the mathematical equivalence between Amdahl's Law and Gustafson's Law. We also focus on an often neglected prerequisite to applying the Amdahl's Law: the serial and parallel programs must compute the same total number of steps for the same input. There is a class of commonly used algorithms for which this prerequisite is hard to satisfy. For these algorithms, the law can be abused. A simple rule is provided to identify these algorithms.
We conclude that the use of the "serial percentage" concept in parallel performance evaluation is misleading. It has caused nearly three decades of confusion in the parallel processing community. This confusion disappears when processing times are used in the formulations. Therefore, we suggest that time-based formulations would be the most appropriate for parallel performance evaluation.
I tried to find out something more about Ingres, which I had never heard of before. Google spits out strange remarks like: "The original RDBMS, but the current version of its QUEL language has been corrupted to acommodate SQL."
Is there a sad and bitter ex-employee somewhere? Or what does that mean?!
WTF, torrents of an unpublished demo? That's illegal. You should know that. Don't you remember HL2 or NT4? They came down hard on those dudes, like Duke himself would've.
Ballmer just happens to receive so cheap question, every once in a while. Any suspicion that a Forbes journalist could generate such lowlife levels of questions seem just outrageusly unlikely. Or?
The first countdown, last November, was called off with just minutes to go due to a computer problem and a stuck liquid-oxygen valve. The second attempt went awry in December when a fuel tank was dented due to a faulty depressurization valve. The third time, computer glitches encountered during a test countdown forced a delay. "
What could a "computer problem" or "computer glitches" be in an event like this? I mean what kind of tests are performed? And how come they are discovered just a few hours or minutes before launch? I cannot see what kind issues it may be. Anyone with a clue?
I agree, it can't be that hard with merely 3,500 books. I have 2,500 books and get upset whenever anything is moved an inch too much. I have total control over more than 99% of my books, without a software catalog. The remainder is attributed to children, wife, and other pets. In fact a series of shelves work very much like a series of directories would do... Wholly cheeses... Hey wait, "How would you recommend me to arrange my card file system for my 20,000+ subdirectoreries on my rig?"
I think many people, including myself, will wait with a (much needed) pc upgrade until MS Vista (DirectX 10) capable hardware is around. Ok, I have run Kororaa with XGL (but normally run Gentoo), and I like it A LOT. However, I have kids... And unless there are compelling Linux gaming alternatives the upgrade may well be Vista...
Also, I may need to by a new tv... An HDTV. Oooo, another 1,000$
So, if the PS3 will work as a Linux-based pc, too, then it is clear. It will be PS3. If it will be cheap, like 500$, then maybe both a new pc and a PS3.
Oh, I almost forgot, I need a new car, too...

Yohoo for more layers, BTW!!!
But, you still can't get 100 gigaflops for 1,500 dollars. :(
Thanks, both SSCGWLB and Junta!
Comparing no 30 and 31 on the list, the Cray XT3 and IBM BlueGene/L Prototype, shows the difference clearly:
Cray XT3 - 2652 CPU:s Rmax 11810 Nmax 1158660
IBM BlueGene - 8192 CPU:s, Rmax 11680, Nmax 331775
My interpretation, the Cray manages to produce a similar Rmax with four times fewer CPU:s thanks to their better bandwidth (as indicated by the higher Nmax). Is that a correct interpretation?

It was stuck in velcro, of course

No, no cover. The real thing. Yet, TNT incessantly can be a bit too much.
I used to half like ACDC's TNT. But now the Tony Hawk series has ruined it.
Well worth a try. A shorter release cycle for a popular game is good. Four years or more?! Agony...
Why not you giving us a stellar link?! blink-blink... ;)
:D
I was so blocked I had to look it up...
Still, the Gaza pyramids are way off the equator. Perhaps the Bosnian were meant to be located at 45N.

The problem is not the proff, but the jury... They don't seem to understand the difference between a (layman's) guess and a (scientific) theory

No, they die once in a lifetime... ;)
No it was not meant to be a joke. You may die from mobile phones, using them too much. Take it seriously. :|

Don't know about security though. But since Xgl is fairly new I wouldn't trust it in a server.
