in the "old" 1.4.x and 1.5.x, I achieved this by using rankfiles (see
FAQ), and it worked very well. With these versions, --byslot etc. didn't
work for me, I always needed the rankfiles. I haven't tried the
overhauled "convenience wrappers" in 1.6 that you are using for this
feature yet, but I see no reason why the "old" way should not work,
although it requires some shell magic if rankfiles are to be generated
automatically from e.g. PBS or SLURM node lists.

I gather there are two sockets on this node? So the second cmd line
is equivalent
to leaving "num-sockets" off of the cmd line?
I haven't tried what you are doing, so it is quite possible this is
a bug.

Built the latest snapshot. Still getting an error when trying to run
on only one socket (see below): Is there a workaround?

---- An invalid physical processor ID was returned when attempting to
bind an MPI process to a unique processor.
This usually means that you requested binding to more processors than
exist (e.g., trying to bind N MPI processes to M processors, where N >
M). Double check that you have enough unique processors for all the
MPI processes that you are launching on this host.
You job will now abort.

Hi,
For benchmarking, we would like to use openmpi with
--num-sockets 1
This fails in 1.6, but Bug Report #3119 indicates it is changed in
1.6.1.
Is 1.6.1 or 1.6.2 available in tar.gz form?
Thanks!
