Aspects of the present invention include a method, system and computer program product that implements a memory management scheme for each processor in a multiprocessor system. The method includes pre-allocating, for each processor in a multiprocessor system, a set of memory buffers; and implementing a metadata bitmap for each pre-allocated set of memory buffers, wherein the metadata bitmap for each pre-allocated set of memory buffers comprises a plurality of bits, and wherein each of the plurality of bits is indicative of a usage state of a corresponding one of the memory buffers within each pre-allocated set of memory buffers.
