OpenHPC: Setup Intel Cluster Checker in OpenHPC

• Packages used to be installable from the repo but Intel removed it - gah! Instructions below are for manual setup

Download/Install latest clck

• Check the intel registration centre for the latest version: https://registrationcenter.intel.com/

 wget http://registrationcenter-download.intel.com/akdlm/irc_nas/tec/9701/l_clck_p_2017.0.014.tgz 
 cd l_clck_p_2017.0.014
 ./install.sh
  
# step 1 serial number: enter CSKW-56T6M5ZD (valid to feb 2017)
# select components and installation params, default is fine. 

# lets add rpms for the compute image
 pwd
 /root/scratch/l_clck_p_2017.0.014
 rpm --root $CHROOT -ivh rpm/*rpm 

# hack - need to make the dirs similar on compute / head. Must be something dont by the install script rather than just the RPMs
 chroot $CHROOT
 cd /opt/intel/clck
 mv 2017.0.014/* 2017.0/
 rmdir 2017.0.014/
 ln -s 2017.0/ 2017.0.014

# and finally recreate the VNFS 
 wwvnfs -y --chroot $CHROOT

Run the cluster checker tool

• Setup the environment

# source the vars
 [boston@head1 clck_sanger]$ grep clck ~/.bashrc 
 source /opt/intel/clck_latest/bin/clckvars.sh 

# create the nodefile 
 for i in {01..20}; do echo node${i} >> nodefile ; done

• Run for the first time

clck-collect -a -f nodefile # this take a god damn eternity!
clck-analyze -f nodefile

Run quick perf test

# check memory bandwidth  (-I is include_only) 
clck -f ./nodefile -I stream -v 5
