Patent attributes
An apparatus to facilitate thread scheduling is disclosed. In one embodiment the apparatus includes a processor comprising a plurality of multiprocessors comprising single-instruction multiple thread (SIMT) execution circuitry to simultaneously execute multiple threads, a shared local memory to be shared by the multiple threads, and scheduling hardware logic to schedule the multiple threads in a thread group for execution across the plurality of multiprocessors in accordance with barrier data. The instructions of the multiple threads are to produce shared data to be stored in the shared local memory when executed by the plurality of multiprocessors, wherein additional instructions of at least a first thread of the multiple threads are to use the shared data, and wherein, in accordance with the barrier data, the first thread is to wait for other threads of the multiple threads to finish producing the shared data before executing the additional instructions.
