Top 500 Supercomputer List Released 167
sundling writes "The heavily anticipated Top 500 Supercomputer list has been released. There is a Sevenfold increase in AMD Opteron processors on the list. Two sections of an IBM prototype took spots in the top 10 and the famous Apple cluster didn't make the list, because it was out of service for hardware upgrades. When complete, the new IBM cluster is sure to take the top spot from the Earth Simulator."

Apple Xserve cluster is IBM too (Score:5, Interesting)
That's not to take anything away from Apple. Both Xserve and the G5 towers that came before them are a great design, reliable, run a great OS, yada yada yada. But the chips are IBM.

In October, HP was impressive, because they filled the bottom of the list with Itanium based superdome: they ranked those all on the same bench figures, that means that those computers were not benchmarked by the customers but by HP. That was a good oportunity for IBM: each time they could put one of their computers on the list, they were sure to throw an HP one out of it, so increase the gap by a factor of 2 (+1 for IBM, -1 for HP) with their main rival.
So I am now wondering if this top500 list still means anything in term of performances and computing power, or is just a promoting tool, where manufacturers can conduct a war on market shares.

Google has an impressive cluster but it's optimized for storage and parallel page access.
I don't think that you could use google's cluster to compute 42 without distributing the work by hand over the different servers because it wasn't built to do calculations but to answer page requests distributed over the different units and to be able to access the most complete mirror of today's web

Assuming an average 1GHz per person, 4 FLOPS per cycle (assuming you could get Altivec working flat strap), 70,000 people turn up that could work out to be... ummm.... 280 teraflops.
You'd have yourself a Universe Simulator with that amount of power!

This is why the US government uses HPC challenge benchmark, in which Linpack is only one measure among eight.

you cluster together a bunch of monolithic kernels. At 8000 processors you aren't going to be able to use 1 monolithic kernel, so the distinction between a medium scalable OS like linux and a large scalable OS like solaris/irix is a bit of a moot point. 1000 OS images instead of 250? It's a nuisance either way.

2) Google's cluster is (probably) a much more distributed system, it would probably take a severe beating in trying to do the LinPack benchmarks that they use to rank the top500. The algorithm requires a lot of data passing, it probably doesn't excel at low latency or even high bandwidth (>16Gb/s) data passing. That's just an educated guess though, AFAIK that information is pretty well secreted. In raw processing power under one roof Google probably has it made, but since most problems (not all, read: *@home) in science and math require lots of data passing between nodes Google will probably get trounced in the top500.

that tells more about "the beast". So far, I just can tell that it is made of linux clusters, containing about 12500 nodes, because in case of clusters you are facing bi processors systems 98% of the time.
Here is the track, if someone wants to hunt the beast.
