Update 4 of the Intel Parallel Studio XE Cluster Edition for Linux 2019 has been installed in /vol/opt/intelcompilers and is available on a.o. clusternodes en loginservers. The older (2019 and 2014) versions can also be found there. To set the environment variables correctly, BASH-users must first run:

source /vol/opt/intelcompilers/intel-2019u4/composerxe/bin/compilervars.sh intel64

After that, icc -V gives the new version number as output. For more info see the page on Intel compilers
