The condor_remote_cluster command has to be run under the regular user account under which you will be submitting your workflow jobs. You donât run it as the root user.

You can use condor_remote_cluster to access two different clusters simultaneously for your workflows. One thing to keep in mind is that each submit file must name the cluster that that job should be run on, like so:

grid_resoruce = batch slurm cluster1.foo.edu

If youâre using DAGMan, you can use the VARS command to set the cluster to use for a whole set of nodes in the DAG.

Dear HTCondor development Team,

I can access two campus clusters, which one is LSF based, the other is Slurm based. Since i am not a administrator of these cluster and i still want to use them to execute one workflow simultaneously, I think i can use condor_remote_cluster to achieve my goal. First question: Can I utilize the two cluster by HTCondor to execute a workflow simultaneously?

Until now, I have done some effort to achieve my goal. I installed HTCondor(MiniCondor) on my PC workstation in the same local area network of campus clusters. I tried to use condor_remote_cluster command to add the LSF cluster and Slurm cluster. I added them successfully and they are shown in the remote cluster list. However, when I try to test using "condor_remote_cluster -t" command. The task can't be dispatched to the remote cluster. There will be an idle task in the condor_q.

Could you provide some suggestions to help me set up my environment? Is it possible for me to achieve my goals without root access of cluster? Looking forward to your reply.

****Log from my PC workstation****

root@ubuntu:~/bosco-test/boscotest.p3SGb# condor_remote_cluster -t cse-liyf@xxxxxxxxxxxx

Testing ssh to cse-liyf@xxxxxxxxxxxxxxxxxxxxx!

Testing remote submission...Passed!

Submission and log files for this job are in /root/bosco-test/boscotest.2DBlK

Waiting for jobmanager to accept job...Passed

Checking for submission to remote lsf cluster (could take ~30 seconds)...grep: /root/bosco-test/boscotest.2DBlK/logfile: No such file or directory

grep: /root/bosco-test/boscotest.2DBlK/logfile: No such file or directory

grep: /root/bosco-test/boscotest.2DBlK/logfile: No such file or directory

grep: /root/bosco-test/boscotest.2DBlK/logfile: No such file or directory

grep: /root/bosco-test/boscotest.2DBlK/logfile: No such file or directory

Then failed.
