mpirun -n 1 IMB-MPI1 error

wanghw — Mon, 16 Oct 2023 03:33:09 GMT

Hi,

I use the rc_verbs and ud_verbs of UCX as transport layer S of OFI, and I get the following error when I run the following command.

./mpirun -n 1 IMB-MPI1

Here's what I'm talking about.

./fi_info -l

./ucx_info -d | grep Transport

export info:

UCX_TLS=rc_verbs,ud_verbs

Does anyone know how to deal with this error?

Thanks & Regards

Hi,

Thank you for posting in intel communities.

Could you please let us know the following details , so that we can reproduce the issue at our end:

1. Which command did you use to set FI_PROVIDER as "UCX" or by default FI_PROVIDER was "ucx"?

2. OS,CPU and Hardware details

Thanks And Regards,

Aishwarya

Hi,
Thanks for the reply.
1.I use command is "export FI_PROVIDER=ucx".
2.I isn't using a real hardware platform, currently simulating hardware behavior using soft.
Other information is shown in the figure below:

Hi,

From the screenshot of cat /proc/version output, we are able to see that , you are using unsupported version of Red Hat(4.5), please update to the supported version of Intel MPI.

Please find the system requirements of Intel MPI:

https://www.intel.com/content/www/us/en/developer/articles/system-requirements/mpi-library-system-requirements.html

From the screenshot of lscpu output , we are able to see that , its not intel processor and we don't provide support other than Intel products so could you please try to run with Intel Processors?

Please find the supported Intel Processors here: https://www.intel.in/content/www/in/en/support/products/873/processors.html#122139

Thanks And Regards,

Hi,

Thanks for the reply.

I'm Sorry. My environment does not allow me to replace systems and hardware.

So I solved my problem by adapting the open Fabric Inter.

However, I think that doing so will result in a reduction in the characteristics of its own optimization.

Thanks & Regards

Hi,

Glad to know that your issue got resolved.

As your initial query is resolved , if you are facing any further issues , please post a new question as this thread will no longer be monitored by Intel.

Thanks And Regards,
