Use AVX2, similar to ICEXA (CPU), but suggest LLVM:

../configure --enable-comms=mpi     \
             --enable-simd=AVX2          \
             --prefix $HOME/prefix-cpu   \
             MPICXX=mpicxx              \
             LDFLAGS=-L$HOME/prefix/lib/ \
             CXXFLAGS="-I$HOME/prefix/include/ -std=c++11 -fpermissive"
make -j 24

Usage of one MPI rank per NUMA domain is recommended, and we have found one NUMA domain per socket to be best as BIOS configuration.
