Abstract: Method, apparatus, and computer program product embodiments of the invention maximize the use of functional processing units in a multicore processor integrated circuit architecture. Example embodiments of the invention determine that instructions to be executed in a functional processor of a local processor core of a multicore processor, are capable of execution in a functional processor of a neighbor processor core of the multicore processor. A compute request is sent to the neighbor processor core to initiate execution of the instructions in the functional processor. A compute response is received from the neighbor processor core, if the functional processor has been able to execute the instructions.
