Abstract
A method, system, and computer program product for reducing false sharing in a distributed computing environment, and in particular to a multi-processor data processing system. A method is proposed to define a virtual address range, within the system memory available to the processors, which will have a finer granularity than the default page size. These smaller sections, called “sub-pages,” allow more efficient memory management. For example, a 64 Kilobyte range may be defined to have a 512 byte granularity rather than 4 Kilobytes, with each 512-byte sub-page capable of being separately managed.
