Hello Mateo,
What version of openmpi are you running?
Also, the OFED-4.17-1 release notes do not claim support for CentOS 7.7. It
supports CentsOS 7.6.
Apologies if you have already tried CentOS 7.6.
We have been able to run openmpi (earlier this month):
OS: CentOS 7.6
mpir
thank you.

Hello Adam,
During the InfiniBand Plugfest 34 event last October, we found that mpirun hang
on FDR systems if you run with the openib btl option.
Yossi Itigin (@Mellanox) suggested that we run using the following options:
--mca btl self,vader --mca pml ucx -x UCX_RC_PATH_MTU=4096
Hello Jorge,
What happens when you go to this link
https://www.open-mpi.org/software/ompi/v3.1/ and click on the file
openmpi-3.1.2.tar.gz in the table? I asks because I am able to download the
tarball without a problem. Maybe the problem you were seeing was temporary.
Cheers.

Hello all,
This may be a silly question but I hope that someone does know the answer.
We use Open MPI to run the Intel Benchmarks to test InfiniBand and RoCE
network fabrics. We recently installed OFED-4.17 and when we attempt to run
the tests, we see the error below.
Command:
/usr/loc
e latest stable RHEL 6.x (probably 6.7,
not sure if we will go with 6.8).
Did you have to recompile Open MPI stacks or any of the existing MPI
software?
Thank you for your input!

Hello Mehmet,
OFED is now around 3.18.2-rc2 and there is
ers.
If it is Mellanox, is it not better to use the MLNX_OFED ?
This information may help us build our cluster. Hence, asking.
Thanks,

Hello Grigory,
I am not sure what Redhat does exactly but when you install the OS, there is
always an InfiniBand Support module during the installation process. We
never check/install that module when we do OS installations because it is
usually several versions of OFED behind (almost obsolete).
Hello Mehmet,
OFED is now around 3.18.2-rc2 and there is talk of an rc3.
We have used many different versions of OFED, and we are now running OFED
3.18.1 rc2 with the latest version of Open MPI with no trouble (OS is CentOS
7.2). What version of Open MPI are you planning to use? What OS,
0 for external access and eth1 for private
network) and MPI should only use the internal network, then you can allow all
traffic on the internal port, and
mpirun --mca oob_tcp_if_include eth1 --mca btl_tcp_if_include eth1 ...
Cheers,
Gilles

Hello Guilherme,
This may be off but try running your mpirun command with the option
“–tag-output”. If you see a “broken pipe”, then your issue may be firewall
related. You could then check the thread “Re: [OMPI users] mpirun command won't
run unless the firewalld daemon is disabled” for how
while
Cheers,
Gilles

Hello Gilles/Jeff,
Thank you for clarifying this.
We have three ports but the RoCE traffic is supposed to use one of the internal
ports. However, we do allow use of one of t

Hello Jeff,
I think what you suggest is likely exactly what we want to see happen. We
run the interop tests with a
b (and the machine where mpirun is invoked, if
that is a different machine).
You could also open your firewall to trust random TCP connections just
between the servers in your cluster.

I have, in the past, have faced similar situations, thus I am curious to know
the answer as well.
Thanks
