Trying to find out if it 's possible to set both below in qmgr for default batch queue…i.e, if user does not specify node/ppn settings in pbs script to be run… set queue batch resources\_default.nodes = 5 set queue batch resources\_default.ncpus = 10 it looks like if I set above, and run qstat -n shows it assigned 5 nodes under NDS but assigned 5 CPU under TSK. so it assigned 5cpus total…I would have thought it would say 50 under TSK …5nodesx10cpu. basically I want to test with setting maximum number of cpus per node…5 nodes x 10 cpus… below is my (default unchanged) qmgr server output: # Create queues and set their attributes. # # # Create and define queue batch # create queue batch set queue batch queue\_type = Execution set queue batch Priority = 50 set queue batch resources\_max.cput = 999:00:00 set queue batch resources\_max.walltime = 999:00:00 set queue batch resources\_default.walltime = 168:00:00 set queue batch resources\_default.nodes = 1 set queue batch acl\_group\_enable = False set queue batch disallowed\_types = interactive set queue batch keep\_completed = 3600 set queue batch enabled = True set queue batch started = True # # Create and define queue interactive # create queue interactive set queue interactive queue\_type = Execution set queue interactive resources\_max.cput = 24:00:00 set queue interactive resources\_max.walltime = 24:00:00 set queue interactive resources\_default.nodes = 1 set queue interactive acl\_group\_enable = False set queue interactive disallowed\_types = batch set queue interactive keep\_completed = 3600 set queue interactive enabled = True set queue interactive started = True # # Set server attributes. # set server scheduling = True set server acl\_host\_enable = False set server acl\_hosts = amedpbswrair000.amed.ds.army.mil set server managers = root@amedpbswrair000.amed.ds.army.mil set server operators = root@amedpbswrair000.amed.ds.army.mil set server default\_queue = batch set server log\_events = 511 set server mail\_from = adm set server query\_other\_jobs = True set server scheduler\_iteration = 600 set server node\_check\_rate = 150 set server tcp\_timeout = 300 set server node\_pack = False set server job\_stat\_rate = 300 set server poll\_jobs = True set server down\_on\_error = True set server mom\_job\_sync = True set server mail\_domain = none set server kill\_delay = 10 set server keep\_completed = 300 set server next\_job\_number = 15528 set server job\_log\_keep\_days = 30 set server moab\_array\_compatible = True set server nppcu = 1 set server timeout\_for\_job\_delete = 120 set server timeout\_for\_job\_requeue = 120 set server note\_append\_on\_error = True ---

Hello zanyviper. Based on your output of qmgr, I am concluding that you are using TORQUE/Moab. This website is for discussions about PBS Professional. Are you attempting to migrate from TORQUE/Moab to PBS Professional, and you are asking how to achieve a similar configuration? ---

Hi Scott apologies, I am not familiar with PBS Professional, but yes we are using Torque/PBS. If this is the wrong forum for my question I apologize. Regards, ---

So a little history for your knowledge. > PBS was originally developed for NASA under a contract project. Altair Engineering acquired the rights to all the PBS technology and intellectual property from Veridian in 2003. Altair Engineering currently owns and maintains the intellectual property associated with PBS, and also employs the original development team from NASA. > > The following versions of PBS are currently available: > > OpenPBS — original open source version released by MRJ in 1998 (not actively developed) > TORQUE — a fork of OpenPBS that is maintained by Adaptive Computing Enterprises, Inc. (formerly Cluster Resources, Inc.) > PBS Professional (PBS Pro) — the version of PBS offered by Altair Engineering that is dual licensed under an open source and a commercial license. PBS Professional has a more modern language specification for job submission, which is called select/place. If using PBS Professional, I would suggest using queuejob hook to evaluate the user’s job submission and modify the select/place requirements to meet your combination check. ---

Scott thank you, I’ll experiment further with what’s available.Thanks for the history also…
