Frequently Asked Questions

Running Jobs

How busy is the pool?

Check to see if there are free resources to run the job:

condor_status -compact

Why isn’t my job starting?

HTCondor can explain why a job isn’t starting (for example, no machine has enough free memory to run the job):

condor_q -better-analyze <JobID>

Can I see standard output/error from my running job?

To peek at the stdout or stderr of a job:

condor_tail [-stderr] [-f] <JobID>

Can I get on my job’s compute node to poke around my job?

To create an SSH session to a running job:

condor_ssh_to_job <JobID>

The session shares the resources of the job. From here you can run top or a debugger.
