Two nodes linpack test error！

[liuzhaoqiang]

The following is my error reporting information. Please help me！！

Thanks！

I've configured ssh-free login and set up nfs file system, using Intel oneapi.

And the firewall is turned off.

CPU：2*E5 2620 v4 per node；1Gb Ethernet；OS：Ubuntu20.04.6-live-server.amd64.iso

My guess is that it's a compatibility issue, who can tell me the real reason！

Hello,

Thank you for reaching out to the Intel communities.

Could you please provide us Intel oneAPI version you are using?

I am successfully able to run the linpack test with FI_PROVIDER= mlx Can find the attached screenshot of linpack test in linpack_text1.png and linpack_test2.png

Could you please check and let us know the FI_PROVIDER you are using?

To find and check for provider can follow the link:

I'm sorry that my description may have misunderstood you. This is just my own guess, because the cpu I use is already very old, but intel OneAPI is very new, so I have this idea.

Hi,

Thanks for the clarification.

Could you please upgrade to the 2023 version of Intel oneAPI and try running the basic IMB benchmark using the below provided command , without specifying any other environment flags.

mpirun -np 4 -ppn 2 IMB-MPI1

Please let us know if you are able to run successfully.

Thanks And Regards,
