[libfabric-users] IB: Resource temporarily unavailable

[Ilango, Arun]

Verbs RDM support is still experimental. rdm pinpong test returns -FI_ENODATA because verbs-RDM doesn't support FI_MSG capability. Also, other RDM tests are not guaranteed to run on verbs for now. Complete support for RDM in verbs is a work in progress.
Thanks,
Arun.

Hi Arun,

Thank you. I confirm that it works now!

Another issue however appears while using the RDM ping pong with IB.
Even though it works with sockets, I get a -FI_ENODATA when I try to run it with verbs. An idea why?

>> Thanks - since Arun mentioned that he can reproduce this, we can probably debug it from there.  The ucmatose errors that you hit are just a mismatch in the data transfer parameters.  Otherwise, I think the lower layer is working okay.
