Sure it would help. I'll test it whenever you're ready.
thanks!

Here’s what I can do

So a key point here is that PU in lstopo output
so I can compare them

Hmmm….and those are, of course, intended to be physical core numbers. I wonder
how they are numbering them? The OS index won’t be unique, which is what is
causing us trouble,

Ugh….we used to have a switch for that purpose, but it became hard to manage
the code. I could reimplement at some point, but it won’t be in the immediate
future.
I gather the issue is that the system tools repor
is can we get mpirun to honor the physical numbering?

So the question is can we get mpirun to honor the physical numbering?

Hmmm…well, it
Hmmm…well, it seems to be working fine in 1.8.4rc1 (I only have 12 cores on my
humble machine). However, I can’t test any interactions with LSF, though that
shouldn’t be an issue:
$ mpirun -host bend001 -rf ./rankfile --report-bindings --display-devel-map
hostname
Data for JOB [60677,1] offset
I am using openmpi v 1.8.3 and LSF 9.1.3.
LSF creates a rankfile that looks like:
RANK_FILE:
==
rank 0=mach1 slot=0
rank 1=mach1 slot=4
rank 2=mach1 slot=8
rank 3=mach1 slot=12
rank 4=mach1 slot=16
rank 5=mach1 slot=20
rank 6=mac
16 matches
