Performability Modelling

Performability modelling and evaluation brings together two disciplines that have long been treated separately in different communities: computer and communication system performance evaluation and system reliability and availability evaluation.<br /> * Provides a single-source reference covering of all aspects of performability evaluation.<br /> * Introduces a new approach to assessing the performance and dependability of systems thus revealing system characteristics that cannot be uncovered separately by performance or reliability evaluation.<br /> * Explains how systems can operate partially in the presence of failures by discussing:<br /> -Capacity of failure prone clusters of transaction processing systems.<br /> -Network throughput when network nodes and links fail.<br /> -Task completion times on degradable multiprocessor systems.<br /> -A variety of modelling and evaluation techniques.<br /> * Features software tool descriptions to support performability evaluations as well as an extensive bibliography.<br /> Computer scientists and engineers will find this excellent overview compulsive reading as will postgraduates and researchers in computer science and related fields.
