RUNTIME FOR AUTOMATICALLY LOAD-BALANCING AND SYNCHRONIZING HETEROGENEOUS COMPUTER SYSTEMS WITH SCOPED SYNCHRONIZATION

摘要

Sharing tasks among compute units in a processor can increase the efficiency of the processor. When a compute unit does not have a task in its task memory to perform, donating tasks from other compute units can prevent the compute unit from being idle while there is task in other parts of the processor. It is desirable to share tasks among compute units that are within defined scopes of the processor. Compute units may share tasks by allowing other compute units to access their private memory, or by donating tasks to a shared memory.
