Intel-MPI 2021: Which TCP ports range is used by default?

[Olivier-Fr]

Hello,

I was not able to find this information into the user documentation...

Could you please share the default TCP ports range used by Intel-MPI 2021?

Many thanks in advance.

Hi,

Thank you for your patience.

There are no default port ranges, you can use "any" port, which is available. But you can specify which ports to use by the I_MPI_PORT_RANGE variable.

Thanks & Regards

Hello Shivani,

Indeed, I apologize for my late feedback on this topic;

After internal coordination with Security guys, we have been able to monitor the ports usage and define the appropriate firewall rules, in conjuction with I_MPI_PORT_RANGE, and to have a "clean" configuration for Intel-MPI usage.

Thanks for your help!

Hi,

Glad to know that your issue is resolved. If you need any additional information, please post a new question as this thread will no longer be monitored by Intel.

Thanks & Regards
