With the number of cores increasing on the various OS platforms, in order to maximize efficiency when there are multiple jobs running on the same physical machine, I believe it would be in Intels best interest to support the rankfile syntax used by OpenMPI. This allows upstream schedulers to minimize numa-node fragmentation as jobs are onboarded and offboarded with differing timings. It would also allow upstream schedulers to allow serial workload to intermingle with parallel workload when the parallel workload can coexist with the serial workload.
The current binding options appear to be good, but there appears to be no capability for the upstream scheduler to define specific cores for execution on a per host basis.
Thanks,
