Abstract
In this paper we propose a method for analysing the performance of Checkpointing schemes that use spare processors in their recovery technique, in a fault-tolerant multiprocessor environment. It is assumed that the multiprocessor system consists of a pool of Checkpointing modules that share spare modules for recovery. This method of analysis is bases on studying of the probability of occurrence of different /states/ that can appear during the execution of a task. These /states/ have as the main variables the availability of the spare module and the number of Checkpointing modules that work simultaneously. In this work we show how this method can be used in several schemes, for example with Roll-Forward Checkpointing Scheme (RFCS) [1] and in Roll-Forward Checkpointing Double Spare Scheme (RFDS) [2]. The results of the analysis of these architectures are compared with the results that we obtain from theirs simulation, and we prove the reliability and universality of our method. |
