Here is the current list of "batch memory operations" one can enqueue on a CUDA stream:

  • CU_STREAM_MEM_OP_WAIT_VALUE_32
  • CU_STREAM_MEM_OP_WRITE_VALUE_32
  • CU_STREAM_MEM_OP_WAIT_VALUE_64
  • CU_STREAM_MEM_OP_WRITE_VALUE_64
  • CU_STREAM_MEM_OP_BARRIER
  • CU_STREAM_MEM_OP_FLUSH_REMOTE_WRITES

these are described in this section of the CUDA driver API manual.

We already support all of these - except for the barrier operation. Let's add support for it.
