In a multiprocessor system with threads running in parallel, workload balancing is facilitated by recognizing a plurality of levels of sub-tasks of a memory synchronization instruction and selectively choosing for at least one thread to do less than all of levels of these sub-tasks in response to the memory synchronization instruction. Which thread waits to synchronize can be impacted by this choice. The programmer can cause a thread expected to be a bottleneck to wait less than other threads. Where one thread is a producer and another thread is a consumer, types of memory synchronization can be adapted to these roles. |
