The purpose of this page is to guide users to the specifics of using HTCondor at NJIT. For an overview of HTCondor and detailed usage instructions, see the user manual.
To include the HTCondor commands in the user's path, at the prompt enter --
module load condor
All of the 66 oslN.njit.edu machines are HTCondor compute nodes. These machines have 8 cores and 16GM RAM. The machines are divided into 5 slots.
Slots[1-4]: 1 Core, 2GB RAM
Slot5: 4 Cores, 8 GB RAM
If a job needs to run on slot 5, a request for RAM > 4GB would need to be included in the submit script. For example -
request_memory = 5000
All jobs are to be submiited from afsaccess1.njit.edu.
HTCondor and AFS
The user manual has a section called "AFS and HTCondor for Users" with specific instructions on using HTCcondor and AFS.
To allow read and write access to the HTCondor processes, the AFS group 'condor_pool' needs the correct permissions. Users should create a separate directory for use with HTCondor. For example --
fs sa condor condor_pool write
Alternatively, files can be copied to /scratch on afsaccess1.njit.edu and jobs submitted from there.
