 Failing to do so, can result in the production of __non-portable__ softwares. On the other hand, we advise you build hardware-bound softwares in all cases in which execution performance is paramount. Failing to do so, can result in the production of __non-portable__ softwares.

-Put particular attention if you are planning  to build  //OpenBLAS// via EasyBuild. In this case defining EASYBUILD_OPTARCH=GENERIC __is not sufficient__ to produce portable software (CPU independent). Use both ''export EASYBUILD_OPTARCH=GENERIC'' in your setup and ''--try-amend=buildopts='TARGET=CORE2 DYNAMIC_ARCH=1 DYNAMIC_OLDER=1 BINARY=64 USE_THREAD=1 USE_OPENMP=1 CC="$CC" FC="$F77"' '' as EasyBuild (''eb'') runtime option. If your compilation fails you can try ''eb -r OpenBLAS-0.3.9-GCC-9.3.0.eb --try-amend=buildopts='TARGET=CORE2 BINARY=64 USE_THREAD=1 USE_OPENMP=1 CC="$CC" FC="$F77"''' instead.+Put particular attention if you are planning  to build  //OpenBLAS// via EasyBuild.
