Just remember, IBM is not sitting down. They are designing their own supercomputers using the same chips that power the xServe. I suspect the computer that defeats the Earth Simulator will will be an IBM, not a Mac.

whooleytoo said:Odd, check this out. One of the authors on this project has already been working on an XServe cluster in the University of Maine.. I wonder how long that page has been up..
nagromme said:These clusters are great to promote Apple by proving the power, quality, and cost-effectiveness of their offerings. But 256 Xserves here, 1000 there, are nothing compared to the volume of mainstream Apple products.
In other words, whether IBM can make enough G5s or not, Xserve sales aren't going to make or break other products' availability.
Also, iMacs if they have a G5 at all are likely to be 1.x GHz.

robertgreen94 said:I believe the reason they are picking 256 nodes is because the US government use to require an inordinate amount of paperwork to justify the need for more than 256 nodes. I doubt they (US GOV) have changed much since I had to look into this a couple of years ago.
Though I could be wrong, maybe they just like the number 256!![]()
Indeed. IBM is hard at work on BlueGene/L that will soundly kick Earth Simulator from the number one position before it's even completed. As it is now, there are two BlueGene/L prototypes on the Top10-list, and they are only a small part of the completed machine which will consist of approximately 130 000 custom built dual core PowerPC 440 processors running at 700 MHz. They are aiming at 350 Tflops next year.wordmunger said:Just remember, IBM is not sitting down. They are designing their own supercomputers using the same chips that power the xServe.

whooleytoo said:Heh! It's pretty cool the guys working on the cluster are here in the forums.
So, here's some things we need to know:
1) XBench scores..
2) Halo framerates.
3) The combined wind-power of 256 XServes' fans (if you don't know this off hand, maybe you can calculate it.. maybe you have a calculator nearby?)
4) Boot times.
5) The name of the guy who has to run around and hit the power button on all the machines.
6) The average air-speed velocity of an unladen sparrow - particularly when flying with (3) as a tailwind.
I'm sure others can come up with more...
BlkBear said:NO cluster computers scale linearly. I don't care what it is. How these large clusters scale depends heavily on the innterconnect. The cost of the low latency/high bandwidth interconnects does not scale linearly either. MACH 5 is only using gigabit ethernet, so you'll see them quite a bit lower than their theoretical maximum performance. If they doubled the number of nodes and still used gigabit ethernet, their % efficiency (actual performance / theoretical performance) will definately go down, that is each node you add gives you less and less additional performance.

Sigh.. can't be all that fast then..clusterman said:1) In due time.
clusterman said:2) Halo a game? Sheesh, we're a university. We don't have time to play games, and can't afford it after dumping out the money for this machine!![]()
clusterman said:3) I'm sure we can calculate it based on the CFM of the machine. I know that when idle, these things are HOT.
clusterman said:4) Unknown for a couple of weeks. We'll be trying out a bunch of different things, most notably diskless nodes.
clusterman said:5) No one needs to press reset. We have remote power on/off equipment that can control every port in the cluster. I insisted on it this time 'round.
clusterman said:6) No supercomputer can determine this answer.
Mudbug said:What word? Who's word? Where'd you hear that?
Scubee said:COLSA's tripleing of their MACH5 is expected next year. From the same source, word is that GigE will not be used for the upgrade.
