Compiling OpenMPI 1.7.2 with CUDA and Intel Compilers 13


If you are intending to compile OpenMPI with CUDA Support, do note that you have to download the feature version of OpenMPI. The version I used for compiling OpenMPI with CUDA is version 1.7.2. The current stable version of OpenMPI 1.6.5 does not have CUDA-Support

1. Download and unpack OpenMPI 1.7.2 (features)

# wget http://www.open-mpi.org/software/ompi/v1.7/downloads/openmpi-1.7.2.tar.gz
# tar -zxvf openmpi-1.7.2.tar.gz
# cd openmpi-1.7.2

2. Configure the OpenMPI with CUDA Support

# ./configure --prefix=/usr/local/openmpi-1.7.2-intel-cuda CC=icc CXX=icpc F77=ifort FC=ifort --with-cuda=/opt/cuda --with-cuda-libdir=/usr/lib64
# make -j 8
# make install
