Ookami is one of the first computers outside of Japan to be powered by the HPE Apollo 80 system, originally developed by Cray and Fujitsu, and uses the Fujitsu A64FX processor. This is the same processor technology found in Fugaku at the RIKEN Center for Computational Science in Japan, one of the fastest and most power efficient supercomputers in the world. The ARM-based processor includes multiple innovations integrated with very fast, low-latency memory that together enable high performance and high power efficiency, contributing to greener technology.

Ookami is made up of 176 Fujitsu A64FX, 2 Nvidia Grace Superchips, 1 AmpereOne-X, 2 Thunder X2, 1 Intel Skylake, and 1 AMD Milan node, for a total of 8,964 cores, and it is coupled with a petabyte of Lustre shared storage.
