OpenSHMEM provides a one-sided communication interface that allows for asynchronous, one-sided communication operations on data stored in a partitioned global address space. While communication in this model is efficient, synchronizations must currently be achieved through collective barriers or one-sided updates of sentinel locations in the global address space. These synchronization mechanisms can over-synchronize, or require additional communication operations, respectively, leading to high overheads. We propose a SHMEM extension that utilizes capabilities present in most high performance interconnects (e.g. communication events) to bundle synchronization information together with communication operations. Using this approach, we improve ping-pong latency for small messages by a factor of two, and demonstrate significant improvement to synchronization-heavy communication patterns, including all-to-all and pipelined parallel stencil communication. |
