Models and algorithms for reliability-oriented task-allocation in redundant distributed-computer systems

Reliability-oriented task-allocation for heterogeneous distributed-computer systems with hardware redundancy is discussed. Redundancy of both processors and communication links is considered. A quantitative allocation model is derived and used to present and discuss models and algorithms for systems...

Beschreibung
Zusammenfassung:	Reliability-oriented task-allocation for heterogeneous distributed-computer systems with hardware redundancy is discussed. Redundancy of both processors and communication links is considered. A quantitative allocation model is derived and used to present and discuss models and algorithms for systems with level-two or level-three redundancy. The results contribute to the body of knowledge on task allocation and provide an alternative to performance-oriented methods.< >
