ABSTRACT:
A computing system comprising a number of multiple processor unit nodes interconnectively connected by a communications system to form a cluster is initialized in a manner that creates separate, independent execution environments for each processor unit. Each multiple processor unit node is configured to operate as a symmetric multiprocessing system with a single, shared memory. During a Startup procedure, memory area segments are created for each processor unit, providing processes running on that processor unit with mutually exclusive access to the associated memory area segment. Startup determines an order of the nodes of the cluster system, and establishes a Coordinator process in the lowest numbered processor unit in the first node of the order. The Coordinator process, when created, directs the remainder of the Startup procedure, and constructs a succession list that identifies the next processor unit in the order to take over the Coordinator process should the first fail.
