In the 55th edition of the top 500, Japan is the leader and uses ARM


Recently the 55th edition of the ranking of the 500 most powerful computers was published in the world and in this new edition compared to the previous one (you can check it in the following link) Japan takes the lead and travels the United States to second place.

And it is that in this classification of June the Japanese Fugaku cluster is the leader and notable for the use of ARM processors.

The cluster of Fugaku is housed at the RIKEN Institute of Physical and Chemical Research and provides a yield of 415.5 petaflops, which is 2.8 more than the leader of the previous ranking.

The cluster includes 158976 nodes based on the Fujitsu A64FX SoC, equipped with a 8.2-core SVE Armv48-A CPU (512-bit SIMD) with a 2.2 GHz clock frequency.

In total, the cluster has more than 7 million processor cores (three times more than the leader of the previous ranking), almost 5 PB of RAM and 150 PB of shared storage based on FS Luster.

Also, it is important to mention that the operating system that is handling all this power is Red Hat Enterprise Linux.

Secondly, we can find to the IBM-deployed cluster at Oak Ridge National Laboratory (USA.). The cluster runs Red Hat Enterprise Linux, includes 2,4 million processor cores (using 9-core IBM Power22 3.07C 22GHz CPUs and NVIDIA Tesla V100 accelerators), providing 148 petaflops performance.

Third place, is the American Sierra cluster, installed at IBM at Livermore National Laboratory based on a platform similar to the Summit and demonstrating performance at the 94 petaflops level (approximately 1,5 million cores).

Fourth place, the Chinese Sunway TaihuLight cluster, which operates in the national supercomputer center of China, which includes more than 10 million cores and shows a performance of 93 petaflops. Despite the close performance, the Sierra cluster consumes half the power of Sunway TaihuLight.

The fifth place is the Chinese group Tianhe-2A, which includes nearly 5 million cores and demonstrates a throughput of 61 petaflops.

While of the new clusters that appeared within the top 10, HPC5 (Italy, Dell EMC, 35 petaflops, 669 thousand cores) and Selene (USA, 27 petaflops, 277 thousand cores) are mentioned, which replaced the US Border cluster. (Dell EMC, 23 petaflops, 448).

And in the case of the Italian Marconi-100 cluster (IBM, 21.6 petaflops, 347 thousand cores) it ranked ninth, and the Swiss group Piz Daint (Cray / HPE, 21.2 petaflops, 387 thousand cores), which ranked sixth in the previous rating now ranked XNUMXth.

The distribution by number of supercomputers in different countries is as follows:

  • China was down: 226 (compared to 228 six months ago). In total, Chinese groups generate 45,2% of all productivity (six months ago, 31,9%).
  • The United States fell 114 (compared to 117 six months ago). Total productivity is estimated at 22.8% (six months ago - 37.8%).
  • Japan remains the same with 29
  • France increased one 19
  • Germany remains with 16
  • Netherlands remains with 15
  • Ireland remains at 14
  • Canada increased to 12 compared to 9 six months ago
  • Britain dropped to 10
  • Italy increased to 7
  • Brazil increased to 4
  • Singapore remains 4
  • South Korea, Saudi Arabia, Norway remain at 3
  • Russia, India, Australia, United Arab Emirates, Switzerland, Sweden, Finland, Taiwan remains at 2.

In the ranking of operating systems used in supercomputers, only Linux has remained for three consecutive years. From the distribution in the use of this year's Linux distributions:

  • 54.4% (49.6%) do not detail the distribution
  • 24.6% (26.4%) use CentOS
  • 6.8% (6.8%) - Cray Linux
  • 6% (4.8%) - RHEL
  • 2.6% (3%) - SUSE
  • 2,2% (2%) - Ubuntu
  • 0.2% (0.4%) - Scientific Linux

Moreover, of the most interesting trends, it is mentioned that the cluster SberCloud with 6.6 petaflops and using Ubuntu 18.04. This one was created by Sberbank on the NVIDIA DGX-2 platform, uses the Xeon Platinum 8168 24C 2.7GHz CPU and has 99,600 cores) it went from 29th to 36th in the ranking for 6 months.
