Computing : get an interactive session on a batchnode

Created by Christoph Beyer, last modified on Aug 21, 2018 11:19

If you want to work in an interactive session rather than submitting a batch job you can use 'condor_submit -i' to get a login on one of the workernodes:

[chbeyer@htc-it01]~/htcondor/testjobs% condor_submit -i
Submitting job(s).
1 job(s) submitted to cluster 2241218.
Waiting for job to start...
Welcome to slot1@bird393.desy.de!
You will be logged out after 7200 seconds of inactivity.
[chbeyer@bird393]~/htcondor/testjobs%


If you use the '-i' option without an individual submit file you get a default session with 3 hours of runtime, 1 core etc.

If you need different settings like CentOS7, longer runtime 2 cores etc. you can define those in a minimal submit file:

[chbeyer@bird064]~/htcondor/testjobs% cat interactive.submit
# Unix submit description file
# sleep.sub -- simple sleep job
+RequestRuntime = 3600 * 3
request_cpus = 2
Requirements = OpSysAndVer == "CentOS7"
queue 1

Using 'condor_submit i interactive.submit' would in this case open an interactive session valid for 9 hours with two cpu-cores on a workernode running CentOS7 ....
