New Chinese Supercomputer Named World’s Fastest System on Latest TOP500
List
June 20, 2016, 4:01 a.m.
System achieves 93 petaflop/s running LINPACK on Chinese-designed CPUs
China draws Equal to the U.S . in Overall Installations
FRANKFURT, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.—China maintained
its No. 1 ranking on the 47th edition of the TOP500 list of the world’s
top supercomputers, but with a new system built entirely using processors
designed and made in China. Sunway TaihuLight is the new No. 1 system with
93 petaflop/s (quadrillions of calculations per second) on the LINPACK
benchmark.
Developed by the National Research Center of Parallel Computer Engineering &
Technology (NRCPC) and installed at the National Supercomputing Center in
Wuxi, Sunway TaihuLight displaces Tianhe-2, an Intel-based Chinese
supercomputer that has claimed the No. 1 spot on the past six TOP500 lists.
The newest edition of the list was announced Monday, June 20, at the 2016
International Supercomputer Conference in Frankfurt. The closely watched
list is issued twice a year.
Sunway TaihuLight, with 10,649,600 computing cores comprising 40,960 nodes,
is twice as fast and three times as efficient as Tianhe-2, which posted a
LINPACK performance of 33.86 petaflop/s. The peak power consumption under
load (running the HPL benchmark) is at 15.37 MW, or 6 Gflops/Watt. This
allows the TaihuLight system to grab one of the top spots on the Green500 in
terms of the Performance/Power metric. Titan, a Cray XK7 system installed
at the Department of Energy’s (DOE) Oak Ridge National Laboratory, is now
the No. 3 system. It achieved 17.59 petaflop/s.
Rounding out the Top 10 are Sequoia, an IBM BlueGene/Q system installed at
DOE’s Lawrence Livermore National Laboratory; Fujitsu’s K computer
installed at the RIKEN Advanced Institute for Computational Science (AICS)
in Kobe, Japan; Mira, a BlueGene/Q system installed at DOE’s Argonne
National Laboratory; Trinity, a Cray X40 system installed at DOE/NNSA/LANL/
SNL; Piz Daint, a Cray XC30 system installed at the Swiss National
Supercomputing Centre and the most powerful system in Europe; Hazel Hen, a
Cray XC40 system installed at HLRS in Stuttgart, Germany; and Shaheen II, a
Cray XC40 system installed at King Abdullah University of Science and
Technology (KAUST) in Saudi Arabia is at No. 10.
The latest list marks the first time since the inception of the TOP500 that
the U.S is not home to the largest number of systems. With a surge in
industrial and research installations registered over the last few years,
China leads with 167 systems and the U.S. is second with 165. China also
leads the performance category, thanks to the No. 1 and No. 2 systems.
The European share of 105 systems (compared to 107 in November 2015) has
fallen and is now lower than the dominant Asian share of 218 systems, up
from 173 in November. Germany is the clear leader in Europe with 26 systems
followed by France with 18 and the UK with 12 systems. In Asia, Japan trails
China with 29 systems (down from 37).
Cray continues to be the clear leader in the TOP500 list in total installed
performance share with 19.9 percent (down from 25 percent). Thanks to the
Sunway TaihuLight system, the National Research Center of Parallel Computer
Engineering & Technology takes the second spot with 16.4 percent of the
total performance – with just one machine. IBM takes the third spot with 10
.7 percent share, down from 14.9 percent six months ago. HPE is third with
12.9 percent, down from 14.2 percent six months ago.
For the first time, the data collection and curation of the Green500 project
is now integrated with the TOP500 project. The most energy-efficient
system and No. 1 on the Green500 is Shoubu, a PEZY Computing/Exascaler
ZettaScaler-1.6 System achieving 6.67 GFfops/Watt at the Advanced Center
for Computing and Communication at RIKEN in Japan.
Other Highlights from the Overall List
Total combined performance of all 500 systems has grown to 566.7 petaflop/s,
compared to 420 petaflop/s six months ago and 363 petaflop/s one year ago.
This increase in installed performance also exhibits a noticeable slowdown
in growth compared to the previous long-term trend.
There are 95 systems with performance greater than a petaflop/s on the list,
up from 81 six months ago.
Intel continues to provide the processors for the largest share – 455
systems or 91 percent – of the TOP500 systems. The share of IBM Power
processors is now at 23 systems, down from 26 systems six month ago. The AMD
Opteron family is used in 13 systems (2.6 percent), down from 4.2 percent
on the previous list.
Hewlett Packard Enterprise has the lead in the total number of systems with
127 systems (25.4 percent) followed by Lenovo with 84 systems. Cray now has
60 systems, down from 69 systems six months ago. HPE had 155 systems six
months ago. IBM is now fifth in the systems category with 38 systems.
A total of 93 systems on the list are using accelerator/coprocessor
technology, down from 104 in November 2015. Sixty-seven of these use NVIDIA
chips, 26 systems with Intel Xeon Phi technology, three use ATI Radeon, and
two use PEZY technology. Three systems use a combination of NVIDIA and Intel
Xeon Phi accelerators/coprocessors.The average number of accelerator cores
for these systems is 76,000 cores per system.
The entry level (No. 500) to the list moved up to the 285.9 teraflop/s mark
on the LINPACK benchmark, compared to 206.3 teraflop/s six months ago. The
last system on the newest list would have been listed at position 351 in the
previous TOP500.
The performance of the last system on the list (No. 500) has systematically
continued to lag behind historical trends for the last 6 years and now
clearly continues to run on a different growth trajectory than before. From
1994 to 2008 it grew by 90 percent per year, but since 2008 it has only
grown by 55 percent per year.
About the TOP500 List
The first version of what became today’s TOP500 list started as an exercise
for a small conference in Germany in June 1993. Out of curiosity, the
authors decided to revisit the list in November 1993 to see how things had
changed. About that time they realized they might be onto something and
decided to continue compiling the list, which is now a much-anticipated,
much-watched and much-debated twice-yearly event.
The TOP500 list is compiled by Erich Strohmaier and Horst Simon of Lawrence
Berkeley National Laboratory; Jack Dongarra of the University of Tennessee,
Knoxville; and Martin Meuer of ISC Group, Germany. | T**E
