Hello,
I had initially thought the same thing about the streams, but I have 2 sockets
with 64 cores each. Additionally, I have not yet turned multithreading off, so
lscpu reports a total of 256 logical cores and 128 physical cores. As such, I
don’t see how it could be running out of streams u
Hi All,
Just my two cents, I think error code 63 is saying it is running out
of streams to use. I think you have only 64 cores, so at 100, you are
overloading most of them. It feels like you are running out of
resources trying to swap in and out ranks on physical cores.

To remove potential interactions, I have found that the issue persists without
ucx and hcoll support.
Run command: mpirun -np 128 bin/xhpcg
Output:

Hello Collen,
Could you provide more information about the error. Is there any output
from either Open MPI or, maybe, UCX, that could provide more information
about the problem you are hitting?

Hello,
I am having difficulty with OpenMPI versions 4.0.2 and 3.1.5. Both of these
versions cause the same error (error code 63) when utilizing more than 100
cores on a single node. The processors I am utilizing are AMD Epyc "Rome"
7742s. The OS is CentOS 8.1. I have tried compiling with bo
