Bioinformatics has made its mark in the supercomputing world: The 4,000-processor Dell cluster installed at the Buffalo Center of Excellence in Bioinformatics in September made it to the #22 spot in the biannual Top500 list of the world’s fastest supercomputers.
Not only is this the highest that a dedicated life science computer has ever climbed on the list, but it exemplifies the quick rise of cluster computing through the high-performance ranks in recent years — a trend further borne out by the appearance of two PC-based clusters in the top ten of the current list (a 5.7-Tflop/s Linux Networx/ Quadrics cluster at Lawrence Livermore National Laboratory at #5 and a 3.3-Tflop/s HPTi/Myrinet cluster at the National Oceanic and Atmospheric Administration’s Forecast Systems Laboratory at #8).
The fastest cluster computer on the June list was an 825-Gflop/s AMD-based system that ranked #35 and now stands at #64.
The twentieth edition of the Top500 list, released last week at the Supercomputing Conference 2002 in Baltimore, Md., boasts a total of 55 Intel-based and 8 AMD-based PC clusters, up from 42 and 7, respectively, six months ago. Including Sun and Alpha-based clusters, the November Top500 list contains a total of 93 clusters, up from 80 in June.
The November list includes 14 cluster computers described as “self-made,” up from 12 six months ago and only 6 one year ago.
In addition to the Buffalo bioinformatics cluster, several other life science-related supercomputers made it to the current version of the list: IBM claims the #111 spot with a 536-Gflop/s system installed at an undisclosed pharmaceutical company; the #128 position with its 468-Gflop/s system at Applera and Celera Genomics; and also holds positions #253 and #353 with two systems for Bayer — one at 250 Gflop/s and one at 212 Gflop/s. SGI has two systems installed at Kyoto University’s Institute for Chemical Research, which are dedicated in part to genomics and bioinformatics research. The 406-Gflop/s and 210-Gflop/s systems give SGI the #155 and #362 spots, respectively. Finally, HP holds the #218 spot with a 296-Gflop/s system at Agilent.
Several life science firms who made it onto the last version of the Top500 list didn’t make the cut-off speed of 195.8 Gflop/s this time around (up from 134.3 Gflop/s in June): Syrrx, Inpharmatica, Aventis Pharma, and Amgen were all bumped from the current list.
Overall, NEC’s 35.9-Tflop Earth Simulator is still far and away the top machine — the next-fastest systems are identical 7.7-Tflop HP AlphaServer systems at Los Alamos National Lab. Tflop-scale systems are becoming commonplace, however. The number of systems exceeding the 1 Tflop/s mark on the Linpack benchmark is now 47, more than double the June list, which included 23 computers above 1 Tflop/s.
Also unchanged were the leading manufacturers by total performance and number of systems. IBM retained the number-one spot in total performance of all the installed systems, with 92.5 Tflop/s compared to HP’s 64.8 Tflop/s and NEC’s 42.7. HP, however, claims 137 total systems compared to IBM’s 129.
The Top500 list is compiled by Hans Meuer of the University of Mannheim, Germany; Erich Strohmaier and Horst Simon of Lawrence Berkeley National Laboratory; and Jack Dongarra of the University of Tennessee. The list ranks computers based on maximal performance acheived on the Linpack benchmark, rather than theoretical peak performance.
