MPI traffic with service Level
Hi all,
I'm interested in the MPI traffic that take into the consideration of the SL(service level)-Path mapping (as decided by SA/SM). For e.g LASH routing algorithm that uses SL/VL as the deadlock avoidance for routing. Is there any way that I can make MPI traffic that uses the SL that as indicated by the SA/SM? Any help/hints would be appreciated. Thanks again.
Thanks,

If MPI is set to use the rdma_cm, it will obtain SL information from the SA. I believe most MPIs support this option through some means. Beyond that, there may be other ways to do this based on the MPI that you're using.

Thanks, Sean! It's working for me now.
