Ray, note there is a bug in nvc compilers since 21.3 (it has been reported and is documented at https://github.com/open-mpi/ompi/issues/9402)
For the time being, I suggest you use gcc, g++ and nvfortran FWIW, the AVX2 issue is likely caused by nvc **not** defining some macros (that are both defined by at least GNU and LLVM compilers), I will take a look at it when I get some time (you won't face this issue if you use GNU compilers for C/C++) Cheers, Gilles On Thu, Sep 30, 2021 at 2:31 AM Ray Muno via users <users@lists.open-mpi.org> wrote: > > Tried this > > configure CC='nvc -fPIC' CXX='nvc++ -fPIC' FC='nvfortran -fPIC' > > Configure completes.
