NVIDIA Builds World’s 7th Fastest Supercomputer w/ AMD Epyc CPUs and A100 Ampere Accelerator

In another win for AMD, NVIDIA has decided to go with the company’s Epyc Rome processors for use in the “Selene” Supercomputer which ranks 7th on the list of world’s fastest SCs.

Selene is the first AMD Zen-based system to be featured in the list of top-10 most powerful supercomputers. The previous AMD powered supercomputer to enter the top-10 rankings was the Titan which featured the Opteron 6274 CPUs and NVIDIA’s K20x GPUs. It was ranked #1 in 2012 but now has slipped down to $12, still impressive considering how long it has really been.

The Selene supercomputer features 280 AMD Epyc 7742 (64 Core) CPUs paired with 1120 A100 GPUs resulting in a meaty final core count of 277760. There are 10 supercomputers across the globe now being fed by AMD’s Epyc processors, but the best is yet to come.

  • #7, Selene, an EPYC 7742 + A100 system for NVIDIA (27.6 PF)
  • #30, Belenos, an EPYC 7742 system for Meteo France (7.7 PF)
  • #34, Joliot-Curie Rome, an EPYC 7H12 system for CEA in France (7.0 PF)
  • #48, Mahti, an EPYC 7H12 system for CSC in Finland (5.4 PF)
  • #56, Betzy, an EPYC 7742 system for Sigam2 AS in Norway (4.44 PF)
  • #58, PreE, a Hygon C86 system for Sugon, China (4.32 PF)
  • #124, Freeman, an EPYC 7542 system for ERDC DSRC (2.5 PF)
  • #172, Betty, an EPYC 7542 system for the US Army Research Laboratory (2.1 PF)
  • #268, Cara, an EPYC 7601 system for German Aerospace Center (1.75 PF)
  • #292, an EPYC 7501 + Vega 20system for Pukou Advanced Computing Center, China (1.66 PF)
  • #483, Spartan, an EPYC 7H12 system for Atos, France (1.26 PF)

The two core supercomputers AMD is presently involved with are part of the US Exascale project:

  • Frontier will have a performance rating of 1.5 ExaFLOPs. It’ll feature AMD’s EPYC Milan CPUs and Radeon CDNA based Instinct GPUs in a 30 MegaWatt design at Oak Ridge. It will be built by Cray with a deployment date in 2021.
  • El Capitan will increase the performance bar to 2.0 ExaFLOPs. It will be powered by EPYC Genoa (4th Gen) CPUs and a future Radeon Instinct GPU in a 30 MegaWatt design at Lawrence Livermore National Laboratory, built by Cray (HPE), for early 2023.
