Preconditions: make sure the new compiler is installed and configured in the Modules system.

Choose from the Modules system, the compiler of choice.

In the root home, create a temp directory where you will copy the OpenMPI tgz

Untar and go in the directory

Run ./configure with the following options (for Intel):

./configure CC=icc CXX=icpc F77=ifort FC=ifort --prefix=/opt/openmpi/1.5.3/intel/2013 --with-tm=/opt/torque --with-openib=/usr

Notice the output directory given with --prefix:  in ARGO there is a convention of storing binaries under /opt/openmpi/OPENMPI_VERSION/COMPILER_NAME/COMPILER_VERSION

Note: for ARGO specify torque and infiniband

Note: should the compiler not be present in Module, you need to set up the env variables for that compiler, including any optimised math library kernels it uses. For example for Intel you have the following env variables (extracted from Module):

prepend-path     PATH /opt/intel/2011/bin
prepend-path     LD_LIBRARY_PATH /opt/intel/2011/lib/intel64:/opt/intel/2011/mkl/lib/intel64
setenv           CC icc
setenv           CXX icpc
setenv           F77 ifort
setenv           FC ifort
setenv           LM_LICENSE_FILE /opt/intel/2011/licenses
setenv           INTEL_LICENSE_FILE /opt/intel/2011/licenses
setenv           INTEL_HOME /opt/intel/2011
setenv           INTEL_MKL /opt/intel/2011/mkl/lib/intel64
setenv           MKLROOT /opt/intel/2011/mkl
setenv           IPPROOT /opt/intel/2011/ipp
setenv           FPATH /opt/intel/2011/mkl/include
setenv           CPATH /opt/intel/2011/mkl/include:/opt/intel/2011/tbb/include
setenv           TBB30_INSTALL_DIR /opt/intel/2011/tbb
setenv           INCLUDE /opt/intel/2011/ipp/include:/opt/intel/2011/mkl/include
prepend-path     MANPATH /opt/intel/2011/man/en_US
