| :!: The environment variable ''EASYBUILD_OPTARCH'' instructs EasyBuild to compile software in a generic way so that it can be used on different CPUs. This is rather convenient in heterogeneous clusters such as xmaris to avoid recompilations of the same softwares on different compute nodes. This convenience comes of course at a cost; the executables so produced will not be as efficient as they would be on a given CPU.

| :!: When compiling OpenBLAS it is not sufficient to define ''EASYBUILD_OPTARCH'' to ''GENERIC'' to achieve portability of the executables. Some extra steps must be taken as described in https://github.com/easybuilders/easybuild/blob/master/docs/Controlling_compiler_optimization_flags.rst. A list of targets supported by OpenBLAS can be found [[https://github.com/xianyi/OpenBLAS/blob/develop/TargetList.txt|here]]. | |:!: When compiling OpenBLAS it is not sufficient to define ''EASYBUILD_OPTARCH'' to ''GENERIC'' to achieve portability of the executables.
