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

Hi Sofya,

The line returns in the config file you pasted from the execute machine got erased a some point in the email chain, so it's a little hard to parse. It looks like you have figured out that you have to set DedicatedScheduler on your execute machines, which is correct.  (Just to note, on your master machine running the collector, negotiator, and schedd, you do not need to set DedicatedScheduler.) I assume that "<FQDN of Master>" in your config is actually replaced in your config by the correct hostname?

When you say that you can multiprocessor jobs now, does that mean you can run vanilla universe jobs with request_cpus = 2?

After you submit a parallel universe job, while it's idle, if you look at the SchedLog in your condor log directory (`condor_config_val log`), are there any lines mentioning something like "10/02/18 13:23:20 (pid:39306) Found 1 potential dedicated resources in 0 seconds"

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.

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

 

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.
