ibrun command line inputs / python-managed sequential parallel jobs Heather Louise Kline https://conferences.xsede.org/c/message_boards/find_message?p_l_id=&messageId=1118669 2016-01-11T23:04:42Z 2016-01-11T23:04:42Z

Update:<br />&#039;ibrun -o 0 -n %i %s&#039;<br />solves this problem. <br /> where %i and %s are the number of processors and the command string provided later. The -o option specifies the offset for the processors, and in this context the offset is always 0. <br /><br />I will be updating our open-source code (SU2) so that this is used automatically on TACC machines in case someone else needs to use our code on XSEDE.

I have a python script (which works well on other systems) that launches a number of parallel jobs sequentially - any recommendations on launching slurm jobs from within python scripts? Especially regarding doing it in the right way for the stampede system?<br /><br />It is an optimization process, where the optimizer is serial and the function calls are parallel, so it&#039;s not feasible to launch each parallel simulation manually. <br /><br />I have tried &#039;ibrun -n %i %s&#039; where the inputs are provided later in the script; however this produced an error about not providing a -o command. <br /><br />Has anyone tried something similar to this, and/or can recommend the correct syntax?<br />This process previously worked with &#039;srun -n %i %s&#039; on a different system, so I think it is just the ibrun inputs I need help with.
