?
Another idea that came to mind was to get an OpenMPI build that would not
have any high performance fabric support and would only work via TCP. So
any advice on how to accomplish my goal would be appreciated.
I realize that performance-wise that is going to be quite... sad. But
currently t
can I improve the performance?

Which also raises another question: if it was built with `--without-orte`
then why do I get an error about failing to get something from ORTE.
The OpenMPI version is `4.1.0rc1` built with `gcc-9.3.0`.
Thank you in advance!

You can try downloading and installing a fresher version of MXM from
mellanox web site. There was a thread on the list with the same problem,
you can search for it.

Try adding path to openmpi libraries to LD_LIBRARY_PATH:
export LD_LIBRARY_PATH=/home/ras536/lib/openmpi/lib:$LD_LIBRARY_PATH

Hello,
Are you making these rules manually or in some automated way?

I'm using the latest ofed from mellanox: 1.5.3-3.1.0 on centos 6.1 with
default kernel: 2.6.32-131.0.15.
The compilation with default mxm (1.0.601) failed so I installed the latest
version from mellanox: 1.1.1227
Best regards, Pavel Mezentsev.
You can try running using this script:
#!/bin/bash
s=$(($OMPI_COMM_WORLD_NODE_RANK))
numactl --physcpubind=$((s)) --localalloc ./YOUR_PROG
instead of 'mpirun ... ./YOUR_PROG' run 'mpirun ... ./SCRIPT
I tried this with openmpi-1.5.4 and it helped.
Best regards, Pavel Mezents
