Ok, looking at the code I can’t see what the issue is. I will run this on our
mlx cluster tomorrow. Should have a working patch then.

Hi, here is the gdb output for additional information:
(It might be inexact, because I built openmpi-2.0.0 without debug option)
Core was generated by `osu_bw'.

Hi, it caused segfault as below:

This patch also modifies the put path. Let me know if this works:

Looks like the put path probably needs a similar patch. Will send another patch
soon.

Hi,
I applied the patch to the file "pml_ob1_rdma.c" and ran osu_bw again.
Then, I still see the bad performance for larger size(>=2097152 ).

Hi folks
I’m looking for someone(s) interested in writing some simple language bindings
(e.g., Python, Java, Fortran) for the PMIx library (which is written in C).
There aren’t a lot of APIs, so I don’t envision this as being a monstrous
effort.
Please let me know if you have any interest - an
