Patrick, is your application multi-threaded? PSM2 was not originally designed
for multiple threads per process.
I do know that the OSU alltoallV test does pass when I try it.

There should have been an error message right above that - all this is saying
is that the same error message was output by 7 more processes besides the one
that was output. It then indicates that process 3 (which has pid 0?) was killed.
Looking at the help message tag, it looks like no NICs were
I think you mean add "--mca mtl ofi" to the mpirun cmd line

Hello:
I am testing a rather large code on several computers. It works fine on all
except for a Linux Pop!_OS machine. I tried both OpenMPI 2.1.1 and 4.0.5. I
fear there is an issue because of the Pop!_OS but before I contact System76 I
would like to explore things further.
I get the follow
What happens if you specify -mtl ofi ?

Hi Howard and Michael,
thanks for your feedback. I did not want to write a toot long mail with
non pertinent information so I just show how the two different builds
give different result. I'm using a small test case based on my large
code, the same used to show the memory leak with mpi_Alltoallv c
Hi Patrick,
Also it might not hurt to disable the Open IB BTL by setting
export OMPI_MCA_btl=^openib
in your shell prior to invoking mpirun

Patrick,
You really have to provide us some detailed information if you want assistance.
At a minimum we need to know if you're using the PSM2 MTL or the OFI MTL and
what the actual error is.
Please provide the actual command line you are having problems with, along with
any errors. In additio
Hi,
I'm trying to deploy OpenMPI 4.0.5 on the university's supercomputer:
* Debian GNU/Linux 9 (stretch)
* Intel Corporation Omni-Path HFI Silicon 100 Series [discrete] (rev 11)
and for several days I have a bug (wrong results using MPI_AllToAllW) on
this server when using OmniPath.
Running
