MULTIPROCESSOR MEMORY MANAGEMENT METHOD AND APPARATUS

摘要

MULTIPROCESSOR MEMORY MANAGEMENT METHOD AND APPARATUS In a multiprocessor system, memory of each adjunct processor comprises global memory and local memory. All global memory is managed by a process manager of host processor. Each processor's local memory is managed by its operating systemkernel. Local memory comprises uncommitted memory not allocated to any process and committed memory allocated to processes. The process manager assigns processes to processors and satisfies their initial memory requirements through global memory allocations. Each kernel satisfies processes' dynamic memory allocation requests from uncommitted memory, and deallocates to uncommitted memory both memory that is dynamically requested to be deallocated and memory of terminatingprocesses. Each processor's kernel and the process manager cooperate to transfermemory between global memory and uncommitted memory to keep the amount of uncommitted memory within a predetermined range.
