Distributed hierarchical control for parallel processing

A description is given of a novel design, using a hierarchy of controllers, that effectively controls a multiuser, multiprogrammed parallel system. Such a structure allows dynamic repartitioning according to changing job requirements. The design goals are examined, and the principles of distributed hierarchical control are presented. Control over processors is discussed. Mapping and load balancing with distributed hierarchical control are considered. Support for gang scheduling as well as availability and fault tolerance is addressed. The use of distributed hierarchical control in memory management and I/O is discussed.<
