Multiprocessor performability analysis

Performability models of multiprocessor systems and their evaluation are presented. Two cases in which hierarchical modeling is applied are examined. Modified stochastic Petri net (MSPN)-based fault models of processor arrays, and a fault handling model to account for near coincident, permanent, transient, and intermittent faults are discussed. Performability results based on capacity-based reward assignments are reported. A simple MSPN-based model for multiprocessor systems, is introduced, and a closed queuing network to derive performance rewards is discussed. Several multiprocessor configurations are compared.<
