1. A method of process assignment in a multiprocessor system having non-uniform memory access storage architecture, the multiprocessor system having multiple interconnected multiprocessing nodes and a main storage distributed among the multiprocessing nodes, wherein each multiprocessing node contains one or more processors and a local main memory, the method comprising the steps of:

  • dynamically reserving a pool of memory space within the main storage during operation of said multiprocessor system;

    allocating the reserved pool of memory space to one or more multiprocessing nodes among the multiple multiprocessing nodes; and

    following allocation of said reserved pool of memory space to said one or more multiprocessing nodes, assigning a process associated with the pool of memory space to a multiprocessing node allocated that pool of memory space such that accesses to local main memory are increased and system performance is enhanced.
