A multiprocessor computer system having a plurality of processing elements comprises one or more core-level hierarchical shared semaphore registers, wherein each core-level hierarchical shared semaphore register is coupled to a different processor core. Each hierarchical shared semaphore register is writable to each of a plurality of streams executing on the coupled processor core. One or more chip-level hierarchical shared semaphore registers are also coupled to plurality of processor cores, each chip-level hierarchical shared semaphore register writable to each of the plurality of processor cores. |
