As a result of the proliferation of low cost off-the-shelf microprocessors and the advances in networking technology, parallel/distributed computing has become increasingly popular. Parallel system are broadly divided into two categories depending on the type of interconnection topology. These are called multiprocessor systems and multicomputer systems. At the system level, a multiprocessor or multicomputer consists of two subsystems. One subsystem is the computation facility which is provided by processors and memories. The second subsystem is the communication network used to support interprocessor communication. These two components are equally important in a parallel processing environment. Any failure of a component in these subsystems result in performance degradation of the system. This dissertation deals with the dependability evaluation of multiprocessor and multicomputer architectures and their behavior with graceful degradation. Three dependability measures, known as reliability, performance availability (PA), and maintainability, are used to evaluate and characterize various parallel architectures. These measures are based on the system requirements for the parallel execution of a task (job) which consists of a number of subtasks.
