Job Environment Variables:
Since the end of April 2018 we care for setting up the shell environment: - As done also on Gridengine we set up the standard user environment - At a minimum PATH and USER are always set to a minimum/standard value - If you use the ClassAd "getenv = True" switch (which is not recommended) you might also set the ClassAd "setENV = False", if you believe that the full submit host environment is usable and valid for your selected batch worker nodes The HTCondor itself sets a very limited shell environment: BATCH_SYSTEM=HTCondor KRB5CCNAME=FILE:/var/lib/condor/execute/dir_<SomeID>/<User>.cc OMP_NUM_THREADS=1 PWD=/afs/desy.de/user/.../<JobDir> SHLVL=3 TEMP=/var/lib/condor/execute/dir_<SomeID> TMP=/var/lib/condor/execute/dir_<SomeID>
