25th TOP500 List Released 274
Chris Vaughan writes "The 25th edition of the TOP500 list of the world's fastest supercomputers was released today (June 22, 2005) at the 20th International Supercomputing Conference (ISC2005) in Heidelberg Germany. The No. 1 position was again claimed by the previously mentioned BlueGene/L System. At present, IBM and Hewlett-Packard sell the bulk of systems at all performance levels of the TOP500. The U.S is clearly the leading consumer of HPC systems with 294 of the 500 systems installed there (up from 267 six months ago)."

The press release [top500.org] is interesting too.

So the MTA can adjust the mesh to compute the tornado in very fine detail while using far fewer points for the huge swaths of calmer weather around it. Traditional supercomputers can't do that well since just distributing the data points to each processor is so much overhead.

I don't know why top500.org didn't provide breakdown by operating system, so I found out myself. Here it is:
328 (65.6%): Linux
73 (14.6%): HP Unix (HP-UX)
52 (10.4%): AIX
16 (3.2%): UNICOS
7 (1.4%): Super-UX
6 (1.2%): Solaris
4 (0.8%): Tru64 UNIX
4 (0.8%): MacOS X
3 (0.6%): SuSE Linux Enterprise Server 9
2 (0.4%): Redhat Enterprise 3
2 (0.4%): HI-UX/MPP
1 (0.2%): SuSE Linux Enterprise Server 8
1 (0.2%): Paragon OS
1 (0.2%): IRIX
I expected a few Windows, but surprisingly there is none at all. Not sure how accurate top500.org's "Operating System" field value is though.
