Details

  • Currently queue::ext_oneapi_submit_barrier is used to enforce sequential ordering of work in out-of-order queues
  • Data dependencies within libCEED can be enforced using the events returned from enqueuing work
  • Relaxing the current sequential ordering would allow for execution overlap where possible
