November 2001

The 18th TOP500 list will be introduced at the SC2001 Conference in Denver, CO (10-16, November 2001).

The latest edition of the twice-yearly ranking finds IBM as the leader in the field, with 32 percent in terms of installed systems and 37 percent in terms of total performance of all the installed systems. In a surprise move Hewlett-Packard captured the second place with 30 percent of the systems. Most of these systems are smaller in size and as a consequence HP's share of installed performance is smaller with 15 percent. This is still enough for second place in this category. SGI, Cray and Sun follow in the number of TOP500 systems with 41 (8 percent), 39 (8 percent), and 31 (6 percent) respectively. In the category of installed performance Cray Inc. keeps the third position with 11 percent ahead of SGI (8 percent) and Compaq (8 percent).

Highlights from the Top 10:

• The Earth Simulator build by NEC remains the unchallenged #1.
• 2 segments of the ASCI Q at Los Alamos are new at #2 and #3 with 7.7 TF/s Linpack each.
• 2 new PC cluster made the TOP 10:
  • #5 is a Linux NetworX/Quadrics cluster at Lawrence Livermore National Laboratory.
  • #8 is a HPTi/Myrinet cluster at the FSL/NOAA.
• Two other systems are new in the TOP10:
  • at #9 a IBM Power4 system installed in UK at the HPCx Consortium,
  • at #10 a IBM Power4 system installed at NCAR.
• 3.2 TF/s are needed to enter the top 10.
• Hewlett-Packard has 4 systems in the TOP 10 followed by IBM with 3 systems, and one from NEC, Linux NetworX, and HPTi each.
• ASCI Red which was in the top 10 since June 1997 (7 times as #1) dropped out of the top 10.
• 7 of the TOP 10 systems are installed in the US, and one in Japan, France and UK each.
