AMD processors

Supported instructions sets

Narval is equipped with 2nd and 3rd generation AMD EPYC processors which support the AVX2 instruction set. This instruction set is also supported by all CPUs at Béluga, Cedar, Graham and Niagara.

However, all nodes at Béluga and Niagara and some nodes at Cedar and Graham also support AVX512 instructions, which are not supported at Narval.
