Can we have concurrent offload on Xeon Phi

Question

On the Nvidia GPU, we can have multiple kernels running concurrently by using the Streams. How about the Xeon Phi? If I offload two part of computation code by different threads, will they run concurrently on the Xeon Phi?

Answer 1

Yes you can have concurrent offload executions on the Xeon Phi, up to 64 by default.

See the --max-connections parameter of the Coprocessor Offload Infrastructure (COI) daemon running on the Xeon Phi /bin/coi_daemon :

  --max-connections=<int>  The maximum number of connections we allow from host
                           processes. If this is exceeded, new connections
                           are temporarily blocked. Defaults to 64.
