Compiling OpenMPI 1.6.5 with Intel 12.1.5 on CentOS 6

Step 1: Download the OpenMPI Software from . The current stable version at point of writing is OpenMPI 1.6.5

Step 2: Download and Install the Intel Compilers from Intel Website. More information can be taken from Free Non-Commercial Intel Compiler Download

 Step 3: Add the Intel Directory Binary Path to the Bash Startup
At my ~/.bash_profile directory, I've added
source /usr/local/intel/composerxe/bin/ intel64
export PATH=$PATH:/usr/local/intel/composerxe/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/RH6_apps/intel/composerxe/lib/intel64:/usr/local/intel/composerxe/mkl/lib/intel64
At command prompt
# source .bashrc

Step 4: Configuration Information
# gunzip -c openmpi-1.6.5.tar.gz tar xf -
# cd openmpi-1.6.5
# /configure --prefix=/usr/local/openmpi-1.6.5-intel-v12.1.5 CC=icc CXX=icpc F77=ifort FC=ifort --with-devel-headers --enable-binaries
# make all install
You will need to include --devel-headers --enable-binaries" or you will face the error Cannot open OpenMPI Configuration mpif90-wrapper-data.txt

Step 5: Test the configuration
$ mpicc -v
cc version 12.1.5 (gcc version 4.4.6 compatibility)
