Hello All,
I have a RoCE interoperability event starting next week and I was wondering
if anyone had any ideas to help me with a new vendor I am trying to help get
ready.
I am using:
* Open MPI 2.1
* Intel MPI Benchmarks 2018
* OFED 3.18 (requirement from vendor)
*
what data is
relevant.
Thank you,
Brendan Myers

Hi Brendan
I doubt this kind of config has gotten any testing with OMPI. Could you rerun
with
--mca btl_base_verbose 100
added to the command line and post the output to the list?

Hello,
I am attempting to get Open MPI to run over 2 nodes using a switch and a
single breakout cable with this design:
(100GbE)QSFP <> 2x (50GbE)QSFP
Hardware Layout:
Breakout cable module A connects to switch (100GbE)
Breakout cable module B1 connects to node 1 RoCE NIC (50GbE)
Hello,
I can confirm that using these flags:
--mca btl_openib_receive_queues P,65536,120,64,32 --mca btl_openib_cpc_include

I am able to run Open MPI version 2.0.1 over a RoCE fabric. Hope this helps

Hello,
I am trying to figure out how I can verify that the OpenMPI traffic is
actually being transmitted over my RoCE fabric connecting my cluster. My
MPI job runs quickly and error free but I cannot seem to verify that
significant amounts of data is being transferred to the other endpoint in my
