This paper presents an o-line diagnosis strategy for parallel message-passing systems. This strategy, called hostdiagnosis, allows a host system to perform centralized diagnosis of the system state, given results of distributed tests performed among the system processors. It is useful for a manufacturing or a maintenance test. Three algorithms that use the host-diagnosis strategy are proposed. Their performance are evaluated using a queuing network model and compared to those of a classic distributed self-diagnosis algorithm. Obtained results show important diagnosis latency savings in case of host-diagnosis algorithms in comparison with the self-diagnosis algorithm.

With the widening gap between processor speeds and disk access speeds, the IΓO bottleneck has become critical. Parallel disk systems have been introduced to alleviate this bottleneck. In this paper we present deterministic and randomized selection algorithms for parallel disk systems. The algorithms
Non-stationary parallel multisplitting iterative methods are introduced for the solution of almost linear systems. A non-stationary parallel algorithm based on the AOR-type methods and its extension to asynchronous models are considered. Convergence properties of the synchronous and asynchronous ver
