AMD processors

Supported instructions sets

Narval is equipped with 2nd and 3rd generation AMD EPYC processors which support AVX2 instructions. This instruction set is identical to the one used by INTEL processors on the Béluga, Cedar, Graham and Niagara nodes. The Narval AMD processors and the Intel processors of the Haswell generation are both restricted to AVX2 and earlier instructions. As such, applications compiled on a Cedar or Graham Broadwell node should function on Narval, otherwise you will need to recompile with the appropriate architecture parameters (see Intel compilers below).
