AMD processors
Supported instructions sets
Narval is equiped 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 et Niagara nodes. The Narval AMD processors and the Intel processors of the Haswell generation are both restricted to the older AVX2 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).
