WARNING: Open MPI failed to open the /dev/knem device #34

Closed garlick closed 1 year ago

garlick commented 2 years ago

This may not be anything we can or should do about in this plugin, but something seen on fluke testing:

WARNING: Open MPI failed to open the /dev/knem device due to a local
error. Please check with your system administrator to get the problem
fixed, or set the btl_sm_single_copy_mechanism MCA variable to none
to silence this warning and run without knem support.

The sm shared memory BTL will fall back on another single-copy
mechanism if one is available. This may result in lower performance.

Don't think this is related to flux-pmix.
