Development reliability node fault-tolerant computing systems by parallel technics

Abstract

Reliability and availability have become increasingly important in today’s computer- dependent world. In many applications where computers are used, outages or malfunction can be expensive, or even disastrous. Which includes high availability, improved throughput and response time. Due to the complexity of such systems, it is impossible to improve computer performance using a single processor, the system must be able to operate correctly despite the presence of certain faults. Fault-tolerance the important technique used to the ability of a system to continue performing its intended function, in spite of faults maintains dependability in these systems. In a broad sense, fault tolerance is associated with reliability.
