Interesting performance hack for Ryzen/TR CPU + MKL → “up to 250% performance gains”
(based on reddit post )
in theory it should work with Julia+MKL ;
Anybody can test / validate ?
“The method provided here does enforce AVX2 support by the MKL, independent of the vendor string result.”
Linux :
export MKL_DEBUG_CPU_TYPE=5
Windows:
@echo off
set MKL_DEBUG_CPU_TYPE=5
call "%MKLROOT%\bin\mklvars.bat" MKL_DEBUG_CPU_TYPE=5
julia
