If it truly is due to mapping/binding and optimization params, then I would expect it to be highly application-specific. The sporadic nature of the reports would seem to also support that possibility. I’d be very surprised to find run time scaling better with srun unless you are using some layo

Repeated here from the OMPI list: We have had reports of applications running faster when executing under OMPI’s mpiexec versus when started by srun. Reasons aren’t entirely clear, but are likely related to differences in mapping/binding options (OMPI provides a very large range compared to sru

Slurm users, I've already posted this question to the OpenMPI and Beowulf lists, but I also wanted to post this question here to get more Slurm-specific opinions, in case some of you don't subscribe to those lists and have meaning input to provide. For those of you that subscribe to one or mor
