Update to 2018 Intel MKL release, move to cvmfs version (!178) · Merge requests · atlas / atlasexternals

Stewart Martin-Haugh requested to merge smh/atlasexternals:MKL_cvmfs into master Nov 17, 2017

I noticed that we pick up our Intel tools from an older AFS directory, while the newest versions are available from CVMFS. It looks like our MKL installation dates back to 2015.

I changed the MKL installation to pick up the new version. I didn't do a full build to test, but I confirmed that the libraries work OK by running a trigger job with

export ATLASMKLLIBDIR_PRELOAD=/cvmfs/projects.cern.ch/intelsw/psxe/linux/x86_64/2018/compilers_and_libraries_2018.0.128/linux/compiler/lib/intel64_lin

My initial results seem to show a 10% improvement in HLT processing time. Potentially something similar could apply for Tier-0.

Cheers, Stewart
