Hi, OpenMPI is configured as follows:
export CC=`which clang` export CXX=`which clang++` export FC=`which flang` export F90=`which flang` ../configure --prefix=/sw/openmpi/3.1.1/aocc20hpcx210-mpifort --enable-mpi-fortran --enable-mpi-cxx --without-psm --without-psm2 --without-knem --without-libfabric --without-lsf --with-verbs=/usr --with-mxm=/sw/hpcx/hpcx-v2.1.0-gcc-MLNX_OFED_LINUX-4.3-1.0.1.0-redhat7.4-x86_64/mxm ..
