==============================================================================
Mannheim, GERMANY, Knoxville, TN, and Berkeley, CA -- In what has
become a much-anticipated event in the world of high-performance computing,
the 18th edition of the "TOP500" list of the world's fastest supercomputers
was released this week.
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).
The list is compiled by Hans Meuer of the University of Mannheim, Germany,
Erich Strohmaier and Horst Simon of the U.S. Department of Energy's
National Energy Research Scientific Computing Center, and Jack Dongarra of
the University of Tennessee. The list was released this week and will be
analyzed at the SC2001 Conference in Denver, CO, November 10 -16, 2001.
Compaq made its debut at the very top of the list with two new systems in
the TOP10. Six months ago the most powerful Compaq system was only listed
at position 43. Eight of the TOP10 systems are installed in the United
States, which demonstrates the leadership of the U.S. in the usage of High
Performance Computing.
The IBM ASCI White system at Lawrence Livermore National Laboratory is
still the number one supercomputer in the world, with a performance of 7.2
teraflop/s (trillions of calculations per second) on the Linpack benchmark.
The number two spot is now taken by the new Compaq AlphaServer SC system at
the Pittsburgh Supercomputing Center, ahead of the IBM SP system at the
Department of Energy's National Energy Research Scientific Computing Center
(NERSC), an unclassified supercomputing center at Lawrence Berkeley
National Laboratory (LBNL) in Berkeley, Calif. At number six is another new
Compaq system at DOE's Los Alamos National Laboratory.
The list now indicates 16 systems exceeding the 1 teraflop/s level using
the Linpack benchmark, eight of these systems are from IBM. The TOP500
already contains 30 systems exceeding 1 teraflop/s level for peak
performance. The two highest ranked clusters are this time the self-made
CPlant at Sandia National Labs and the Titan Itanium cluster from IBM
installed at the NCSA, at numbers 29 and 34 respectively. The number of
clusters build with small SMPs as building blocks steadily increases in the
TO500. There are now 43 such systems listed. The dominant architecture with
50 percent of systems are still the massively parallel systems (MPP)
followed by clusters of large SMP systems, the so called constellations (29
percent).
The list exhibits unbroken growth at all ranges of performance. The total
combined performance of all 500 computers on the list is 134.4 Tflops/
compared to 108.8 Tflop/s six month ago and 88.1 Tflop/s one year ago. The
"slowest" system on the newest listing is now 94.3 gigaflop/s, compared to
67.8 Gflop/s 6 months ago and 55.1 Gflop/s in November2000.
The new TOP500 list, as well as the former lists, can be found on the Web
at http://www.top500.org/ . In a BOF Session at SC2001, Wednesday, November
14th, 5:30 - 7:00 pm, room A107, the authors will give detailed insight in
the new list.
TOP500 Certificates for all entries in the 18th list may be picked up in
Denver at the SC Exhibition, booth #520 (Nov 13-15).
