I am using spack, with the instruction on https://developer.amd.com/spack/amd-optimized-cpu-libraries/. However, I don't know what is "threads"

Hi, The "threads" option enables the compilation of the threaded FFTW library. You can compile the library with either of the two options: threads=on : It will use posix threads on unix and win32 on windows openmp=on : It will use OpenMP threads.

Thanks.
