Re: [HTCondor-users] Dedicated Scheduler Config to enable Parallel Jobs.

This is normal for parallel universe. The reason is that the execute nodes must configured to respond to a single dedicated scheduler, so only jobs submitted to that scheduler will ever run.

You would split your execute nodes up by configuring ½ of them to use schedd A as the dedicated scheduler, and and 1/2 to use schedd B as the dedicated scheduler. Then you could submit jobs to either schedd A and schedd B, but those jobs would never be able to use more than ½ of the execute nodes.

This is the same whether your schedd and/or execute nodes are Windows or Linux.

I can run multi-processors jobs now but in order to submit a multi-cpu parallel job I have to submit it from a dedicated scheduler. In this case, the master. It means I have to login to the remote machine and submit from there.

Is this behavior expected? Can it be because I run it on Windows and it's it has some limitations?

Thank you.

Hello,

I'm trying to configure to enable Parallel Jobs on HTCondor pool running on Windows.

I'm using Condor version 8.4.1

My condor_config on master:

I did condor_reconfig -all and condor_restart

I changed condor_config on two nodes out of 9 to see if it works. It's a condor config from one of the nodes:

I did condor_reconfig -all and condor_restart

But if I submit a parallel job it stack forever in idle mode.

This is an example of the job:

universe = parallel

should_transfer_files = Yes

when_to_transfer_output = ON_EXIT

notify_user = <email address>

machine_count = 1

request_cpus = 2

notification = Always

run_as_owner = true

getenv = true

log = sleep_log.txt

output = sleep_stdout.txt

error = sleep_stderr.txt

executable = sleep.bat

queue

Please advise.

Thank you.
