# This script must be run as SU to install intel mkl and icc (11.0.081) in a Linux Rocks cluster or Centos7 in /share/apps/intel


# prerequisite: /share/apps has already existed. If use mkdir to make one (this is required for CentOS system; for Rocks existence of /share/apps is already established by default).

### download intel licencse
mkdir /share/apps/intel
mkdir /share/apps/intel/licenses 
cd /share/apps/intel/licenses
wget http://www2.fizik.usm.my/configrepo/howto/intel/licenses/licenses.tar
tar -xvf licenses.tar
### end of download intel licencse

# Step -1: It is possible that during the installation process, the intel installation may complain about "Missing critical pre-requisite -- missing system commands". This is because Rocks Linux 6 does not come preinstalled with compat-libstdc++-33.i686. One needs to install this compatable library via 

yum install compat-libstdc++-33.i686 

# Step 0
# Must  set SELINUX to permissive by editing the file /etc/sysconfig/selinux
# either: 
# echo 'SELINUX=permissive' >> /etc/sysconfig/selinux
# or better still, issue the command as root:
setenforce 0

## Download the source file and licenses from www2.fizik.usm.my into /share/apps/configrepo
cd /share/apps/configrepo
wget http://www2.fizik.usm.my/configrepo/howto/intel/l_cproc_p_11.0.081_intel64.tar
tar -xvf l_cproc_p_11.0.081_intel64.tar

# Step no: 4 of 7 | Installation location
# --------------------------------------------------------------------------------
# Please provide the location where the Intel(R) Fortran Compiler Professional
# Edition for Linux* version 11.0 will be installed.
# --------------------------------------------------------------------------------
#    1. Install in the "/opt/intel/Compiler/11.0/081" directory [default]
#    2. Specify a custom installation directory
##############################################################################
# choose Option 2 to custom install it in the directory /share/apps/intel/Compiler/11.0/081

# Any user to use icc should source the path in his/her ~/.bashch. To do so, add the following lines in the ~/.bashrc file for $USERS. By default, to avoid confusion you should use the mkl libraries of ifort version 11.1.072, but not the mkl from icc 11.0.081. Hence you are advised not to source  /share/apps/intel/Compiler/11.0/081/mkl/tools/environment/mklvarsem64t.sh intel64 on $USERS/.basrhc

### sourcing (to be added into $USER/.bashrc
source /share/apps/intel/Compiler/11.0/081/bin/iccvars.sh intel64
source /share/apps/intel/Compiler/11.0/081/bin/intel64/iccvars_intel64.sh intel64
#source  /share/apps/intel/Compiler/11.0/081/mkl/tools/environment/mklvarsem64t.sh intel64

## Add the icc library path, the bin path and mkl that comes along with icc to .bashrc of any users who wants to use them in a cluster environtment:

### icc bin path and icc library, 11.0.081
# export LD_LIBRARY_PATH=/share/apps/intel/Compiler/11.0/081/lib/intel64
# export PATH=/share/apps/intel/Compiler/11.0/081/bin/intel64:$PATH

### mkl library path (icc, 11.0.081)
#export LD_LIBRARY_PATH=/share/apps/intel/Compiler/11.0/081/mkl/lib/em64t
