#! /bin/bash

## this scrip installs intel mpi version 4.1.0.024 in /share/apps/intel of a Rocks cluster. It must exceted as su. 

#obtain license file from https://registrationcenter.intel.com/en/forms/?productid=2163 by filling up the Intel® Parallel Studio XE Cluster Edition for Linux form. Trial license will be sent via email. The serial number, e.g. VC88-CSPFVCHD will be needed in order to activate the intel compileres (icc, ifort, mkl and impi) for a month. Skip this if intel icc has been installed based on http://www2.fizik.usm.my/configrepo/howto/intel/inst_icc_11.0.081_sa, as licensed would have been installed. If valid license file is already in existence, installation will prompt for 'used existing licence', so that no serial will be needed in this case.

# impi is not to be used as the default mpi library. If a $USER wishes to use impi lib and its executable, he has to type the following line in the terminal, 

# sh /share/apps/intel/impi/4.1.0.024/bin64/mpivars.sh intel64

# Alternatively, if $USER wishes to permanantly make impi as the default mpi, he has to add the line in his/her ~/.bashrc file.
