NVIDIA’s Selene supercomputer takes a bow


When the 55th. Top500 supercomputer rankings were published, in at number 7 with a bullet was newcomer Selene, which is owned by NVIIDIA and uses AMD’s Rome EPYC 7742 processors (64 cores, clocked at 2.25GHz) and NVIDIA’s own latest A100 accelerators.

Selene is now a part of the world’s fastest AI supercomputer, Saturn V, clocking in at nearly five Exaflops

“NVIDIA is a data center scale computing company and we use our own DGX SuperPOD based supercomputer to advance the field of AI, create new products and to provide a reference to our customers who want to build modern AI datacenters.

“The world’s most accurate AI for reading comprehension called Megatron-BERT was created on our supercomputer and it also powers the development of our platforms for conversational AI, autonomous driving, AI in gaming, healthcare, smart cities and robotics”.

Selene uses 277,760 cores and 500 Terabytes of RAM to achieve 27.58 petaflops and the system is networked using NVIDIA’s Mellanox HDR Infiniband technology.
