The new supercomputer, a BullSequana XH2000, provided by Atos, will give Norwegian researchers more than 5 times more compute capacity than previously, with a theoretical peak performance of 6.2 petaFLOPs.

This new system provides UNINETT Sigma2 with a powerful environment for large-scale computing. "It is of the outmost importance for Norwegian researchers to have access to e-infrastructure at a high international level in order to be competitive, and a continuing growing number of research groups will benefit greatly from the computational power of the new system", says Gunnar Bøe, Managing Director of UNINETT Sigma2.

The supercomputer, named after the Mary Ann Elizabeth (Betzy) Stephansen, the first Norwegian woman with a Ph.D in mathematics, is installed at NTNU in Trondheim, will be available to users before the next allocation period.

Betzy technical specifications

  • The system comprises of 1344 compute nodes each equipped with 2 x 64 core, 2nd generation AMD EPYC™ processors, code name ‘Rome’, for a total of 172032 cores installed on a total footprint of only 14.78m2. The total compute power will be close to 6.2 petaFLOPS.
  • The system will consume 952kW of power and 95% of the heat will be captured to water and reused.
  • The computes nodes are interconnected with the new generation of Mellanox HDR InfiniBand technology.
  • Betzy’s data storage is provided by a high performance DDN parallel Lustre file system with 2.5 PB capacity

The TOP500 winner is from Japan

The Japanese system Fuagki, installed at RIKEN Center for Computational Science in Kobe, captures the TOP500 Crown as the most powerful supercomputer in the world with a CPU-only system equipped with ARM SVE chips.
 
The 55th edition of the TOP500 was announced at ISC High Performance Digital Conference 22 June.
