Linux is now in the top 500 supercomputers

Check these top 500

Recientemente the 53rd edition of the classification of the 500 computers was presented (TOP500) with the highest performance in the world. In this new published issue, a dozen leaders were unchanged, with the exception of the promotion to fifth place in the ranking of the new Frontera cluster produced by Dell for the Texas Computer Center.

The cluster runs on the CentOS 7 operating system and includes more than 448 Xeon Platinum 8280 28C 2.7GHz-based cores. The total size of the RAM is 1.5 PB and the performance reaches 23 petaflops, which is 6 times less than the leader of this top.

IBM Deploys Summit Lead Group at Oak Ridge National Laboratory (USA). The cluster runs Red Hat Enterprise Linux, includes 2.4 million cores processor (using 9-core IBM Power22 3.07C 22GHz CPUs and NVIDIA Tesla V100 accelerators), providing 148 petaflops performance.

The second place is occupied by the American Sierra group, It was installed at Livermore National Laboratory by IBM based on a platform similar to the Summit and dshows performance in 94 petaflops (approximately 1,5 million cores).

Third is the Chinese Sunway TaihuLight cluster, operating in China's national supercomputer center, which includes more than 10 million cores and shows the performance of 93 petaflops.

Despite similar performance indicators, the Sierra cluster consumes twice less power than the Sunway TaihuLight.

In fourth place was the Chinese group Tianhe-2A, which includes almost 5 million cores and demonstrates a yield of 61 petaflops.

For Top100, the entry threshold increased from 1703 to 2395 teraflops, the total throughput of all systems in the year's ranking increased from 1.22 to 1.559 exaflops (four years ago there were 361 petaflops).

Intel CPUs lead the way: 95.6% (95% a year ago), followed by IBM Power with 2.6% (up 3%), SPARC64 - 0.8% (1.2%) in fourth place, 0.4% in AMD 4th. (0.4%).

Trends

Lomonosov 2, for the year, went from 72 to 93rd place in the ranking. The cluster at Roshydromet fell from 172 to 365.

The Lomonosov and Tornado groups, which ranked 227 and 458 a year ago, were removed from the list.

The distribution by number of supercomputers in different countries, comparison of now versus a year ago:

  • China: 219 (206 - a year ago)
  • United States: 116 (124)
  • Japan: 29 (36)
  • France: 19 (18)
  • UK: 18 (22)
  • Germany: 14 (21)
  • Ireland: 13 (7)
  • Netherlands: 13 (9)
  • Canada 8 (6)
  • South Korea: 5 (7)
  • Italy: 5 (5)
  • Australia: 5 (5)
  • Singapore 5
  • Switzerland 4
  • Saudi Arabia, Brazil, India, South Africa: 3
  • Russia, Finland, Sweden, Spain, Taiwan: 2

The general distribution by number of supercomputers in different parts of the world is as follows: 267 supercomputers are in Asia (261 a year ago), 127 in America (131) and 98 in Europe (101), 5 in Oceania and 3 in Africa.

Systems used

In the ranking of operating systems useds on supercomputers, for two years only Linux remains.

Linux distribution distribution (currently vs a year ago):

  • 48.8% (50.8%) do not detail the distribution
  • 27.8% (23.2%) use CentOS,
  • 7.6% (9.8%) - Cray Linux
  • 3% (3.6%) - SUSE,
  • 4,8% (5%) - RHEL
  • 1.6% (1.4%) - Ubuntu
  • 0.4% (0.4%) - Scientific Linux

Cluster Manufacturers

  1. Lenovo ranked first: 34.6% (23.4% a year ago)
  2. Inspur took second place: 14.2% (13.6%)
  3. Sugon 12.6% (11%) ranked third,
  4. Hewlett-Packard - 8% (15.8%) moved from second to fourth place
  5. Cray ranks fifth with 7.8% (10.6%)
  6. Bull 4.2% (4.2%)
  7. DellEMC 3% (2.6%)
  8. Fujitsu 2.6% (2.6%)
  9. IBM 2.4% (3.6%)
  10. Penguin Computing - 1.8%
  11. Huawei 1.4% (2.8%).

The minimum performance threshold to enter the Top500 increased throughout the year from 715.6 to 1022 teraflops, that is, now there are no groups underperforming petaflops (a year ago, only 272 groups showed more performance than petaflops, two years ago, 138, three years ago, 94).

At the same time, a new version of the alternative classification of Graph 500 cluster systems is available, which focuses on evaluating the performance of supercomputer platforms related to the simulation of physical processes and processing tasks for large data sets typical of such systems.

The Green500 ranking is no longer released separately and merged with the Top500, as energy efficiency is now reflected in the main Top500 rating (LINPACK FLOPS ratio to power consumption in watts is taken into account).
