#2. Intel Paralell studio, parallel_studio_xe_2017_update2.tgz (huge, ~ 4 GB)
cd $testdir

# Preferably install intel parallel studio in cluster mode (assuming the are already many nodes up and running in the cluster). To this end, first create a machine.LINUX file in /share/apps/configrepo to list down all ssh-reachable nodes, i.e., 192.168.1.10, 192.168.1.21, 192.168.1.22, .... This can be done using the folling command:

echo 192.168.1.10 > temp.dat; $(coc-sshreachable | cat /share/tmp/ssh-reachable2.dat > temp2.dat); cat temp.dat temp2.dat > machine.LINUX; cat machine.LINUX; rm -rf temp.dat temp2.dat;
mv machine.LINUX /share/apps/configrepo
# Note that the first entry in machine.LINUX must be the frontend, 192.168.1.10.

chmod +x inst_intel_parallelstudioXE17_opt.txt
./inst_intel_parallelstudioXE17_opt.txt

# Choose to install in the default directorly /opt/intel. Use 'cluster intallation' (instead of the default single-machine) option  to group-install intel parallel studio in all sshreachable nodes, as already listed in /share/apps/configrepo/machine.LINUX. Tick the 'check shared directory option' while doing the installation. 

# After the completion of the installation of intel parallel studio in all nodes, it is possible that the necessary symbolic link required by later applications is not done /opt/intel. For the sake of robustness, perform the symbolic linking in all nodes via the folliwing command line, i.e.,

cd /opt/intel
coc-sshreachable
host2=$(cat /share/tmp/ssh-reachable2.dat)
for i in $host2
do
        lastdir=compilers_and_libraries_2017
#$(cd /opt/intel; ls -d */ | grep compilers_and_libraries | awk 'END {print}')
        yn=$(ssh -X -Y -oStrictHostKeyChecking=no $i "if [ -d  /opt/intel/compilers_and_libraries ]; then echo 1; else echo 0; fi")
        echo $i $yn

        if [ "$yn" -eq 1 ];then
                echo /opt/intel/compilers_and_libraries exists in $i. Not to do symbolic link
        fi

        if [ "$yn" -eq 0 ];then
                echo /opt/intel/compilers_and_libraries does not exist in $i. Do symbolic link
                ssh -X -Y -oStrictHostKeyChecking=no $i "cd /opt/intel; ln -s $lastdir compilers_and_libraries"
