# This script must be run as SU. It will install intel mkl and ifort (11.1.072) in the directory /share/apps of Rocks Linux cluster

### download intel licencse

#### download intel ifort 11.2.072 source 
mkdir /share/apps/configrepo
cd /share/apps/configrepo
wget http://www2.fizik.usm.my/configrepo/howto/intel/l_cprof_p_11.1.072.tgz

# 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
# Be sure to set SELINUX to permissive by editing the file /etc/sysconfig/selinux
# echo 'SELINUX=permissive' >> /etc/sysconfig/selinux
# May have to reboot if selinux is changed.


#### Manual intervention is required. Standby and manually do the following #########

tar -zxvf l_cprof_p_11.1.072.tgz
cd /share/apps/configrepo/l_cprof_p_11.1.072
cd l_cprof_p_11.1.072
