Hello BenIt will be back, at least for the majority of platforms (those without heterogeneous memory).

Hi,
Quick question: what's the equivalent of "--map-by numa" for the new
PRRTE-based runtime for v5.0? I can see "package" and "l3cache" in the
help, which are close, but don't quite match "numa" for our system.
In more detail...
We have dual-socket CLX- and SKL-based nodes with sub-NUMA clustering
enabled. This shows up in the OS as two packages, each with 1 L3 cache
domain and 2 NUMA domains. Even worse, each compute node effectively
has its own unique mapping of the cores of each socket between the NUMA
domains.
A common way of running for our users is with 1 MPI process per NUMA
domain and then some form of threading within the cores associated with
that domain. This effectively gives each MPI process its own memory
controller and DIMMs.
Using "--map-by numa" worked really well for this, since it took care
of the unique core numbering of each node. The only way I can think of
to set up something equivalent without that would be manually
enumerating the nodes in each job and building a rank file.
I've include an example topology below.
Or do you think this is better as a GitHub issue?
Thanks,
Ben
