A Bit Delayed: Newest Top 500 HPC List


I am a bit late in linking to this one. Oops! Too many things that go on for me to always catch everything. Anyways, some stats from the list.

In the top ten, five systems are IBM. One is a Sun. Another is a Cray (sad that). Two are SGIs. One is an HP system. There are three European systems, one Indian system, and the rest are American. There are none that Japanese at all: their fastest one is ranked at 16, one behind the Cray downstairs. The much vaunted Earth Simulator that dominated the list for so long barely eeks it into the Top 50 systems.

Vendor shares of those that have two digit or more systems on the list are IBM (42%), HP (36.6%), Dell (5.4%), SGI (5.4%), and Cray (3.2%). 12.8% of the list, all the remaining systems, are split between 20 different "vendors." Three systems are "self made" ones.

America has 51.4% of the HPC systems - 257 - while have 59.8% of the sustained performance (sustained is all that matters, folks). If you combine the EU countries - much to the protest of the Poms, I a sure - they have a total of 168 systems (33.6% of total) with 27.8% of the sustained performance. There's a huge drop off then. Japan has the next most systems with 22 (4.4%) with 4.7% of the total flops. China comes in next with 2.4% of the total systems (12) and 1.1% of the total sustained flops. Then comes Russia with 9 systems and 1.4% of the sustained flops.

There are a few surprises there. The most surprising member of the list - to me - though happens to be....Slovenia. One system. The most surprisingly lightweight member of the list is...Canada, only 2 systems. Japan comes across as the second most surprisingly lightweight member of the list: their systems are smaller and fewer than I would have expected.

Anyway, there are only two (!) vector processor systems left on the list.

At any rate, go take a look at the list. Very interesting.
