Recently I moved my codes to the UF HiPerGator machines (also referred to as the HPC machines) which are running RHEL 7. Info about HiPerGator can be found on:

One issue that I ran into was that the grid tools used by CMS, e.g. voms-proxy-*, uberftp, gfal-copy, globus-url-copy, etc, are not automatically set up. To get them working, I got the following instructions from Bockjoo Kim:

source /cvmfs/oasis.opensciencegrid.org/osg-software/osg-wn-client/current/el7-x86_64/setup.sh
export X509_CERT_DIR=/cvmfs/cms.cern.ch/grid/etc/grid-security/certificates
