Thanks, David. What’s not clear to me is where to set those? From reading that file, it looks like I could still set SSE_TYPES and the section of that file around the Intel compiler would make use of it. Same goes for the variables you suggest them, but I’m not clear if I should set those like: OPT_CFLAGS="-O3 -xAVX -axCORE-AVX2” ./run_cmake, or if I set those with -D inside the run_cmake script, or what.
Thanks again!
