HTCondor

! Please note that those pages are not intended to be what our Official Documentation will look like, but a rather a quick response to all your enthusiasm in using the new HTCondor cluster !

Changes in the cluster:

• OS: EL7 flavor (CentOS7)
• Batch System: HTCondor v8.9.8
• Computing Element: HTCondor-ce
• Mass Storage: /pnfs is now accessible using posix nfs in read/write mode
• User Interfaces (UI): mshort (m1, m2, m3), mlong (m4, m5, m6, m7)

HTCondor features Documentation:

• First guide to job submission
• Using the python API

! Important !
/user and /pnfs are both accessible everywhere on the cluster.
So there is no need to use HTCondor transfer features when submitting jobs to transfer files to/from any of those 2 directories. Just call/copy them directly from within your jobs.

You have 2 ways to copy files:

• should_transfer_files = YES: [not recommended] that will copy everything not mentionned in your .sub files along with the .out & .err logs. So you need to remove all files you don't want copied before your job ends (like unneeded inputs, intermediary file, etc)
• should_transfer_files = NO: you need to copy files yourself within your job script. You can easilly copy files to /user & /pnfs with a simple cp, or grid tools if you prefer.

Known Issues

• kde.sh issue: does not affect your job
• $HOME: it is not defined (yet), so calling anything with it will fail
