Luís Fernando Friedrich, Rafael Luiz Cancian, Rômulo Silva de Oliveira, Thadeu B. Corso · 2001
The increasing complexity of several industrial applications claims for execution environments supporting parallel and real-time computing. Multicomputer systems have a great potential for high performance and reliability because of their expressive number of processors and communication channels. This paper presents an evaluation of real-time computing on a parallel environment that is based on the association of a multicomputer model and a demand driven communication mechanism. The proposed environment allows a reduction of the communication problems presented by conventional multicomputer environments and, also provides a high flexibility in dealing with the problem of mapping the inter-process communication of a parallel program into the interconnection network of a multicomputer architecture. The main goal of the proposed work is to evaluate the performance of the proposed environment for predictable parallel/distributed real-time computing.
