  • Multiprocessor system with private memory sections
    Publication number: 20080109624
    Abstract: A system and method for providing multiprocessors with private memory are described. In one embodiment, a first chip couples to a plurality of processor chips. In one embodiment, the first chip includes memory management circuitry and system coherency circuitry. In one embodiment, the memory management circuitry assigns segments of memory to be system memory sections or private memory sections within a segment. In one embodiment, the system coherency circuitry maintains coherence of entries in the system memory.

  • Dynamic load balancing of applications
    Patent number: 5630129
    Abstract: An application-level method for dynamically maintaining global load balance on a parallel computer, particularly on massively parallel MIMD computers. Global load balancing is achieved by overlapping neighborhoods of processors, where each neighborhood performs local load balancing. The method supports a large class of finite element and finite difference based applications and provides an automatic element management system to which applications are easily integrated.
