In this paper, a two-phase method is presented for the selection of machines to be kept on the shop floor and the assignment of parts to be manufactured for these machines. In the first phase, dynamic programming or a heuristic procedure identifies a set of feasible solutions to a "knapsack problem." In the second phase, implicit enumeration technique or a greedy algorithm solves an assignment problem. The proposed method is written in language C and runs on a parallel virtual machine called PVM-W95. The results obtained from the parallel implementation on several examples which are found in the literature, as well as examples generated at random, were used to establish a comparison with the sequential algorithm and to perform a speedup analysis.

“…The PVM-W95 is a message passage environment that offers the required resources for developing concurrent programs using the C (or C++) programming language, on a network of PCs running the Windows95/NT operating systems. This environment is entirely compatible to the original PVM platform for UNIX systems [8]. The choice of PVM is mainly due to its simplicity and widely utilization, being a de facto standard for distributed/parallel computing.…”

A Deus, por ter me acompanhado em todos os momentos. RESUMO A computação paralela, realizada com o uso de sistemas computacionais distribuídos e ambientes de passagem de mensagens, é uma boa alternativa para a implementação de aplicações que necessitam de desempenho elevado. Entre os ambientes existentes, o PVM (Parallel Virtual Machine) destaca-se como um sistema que permite a utilização do paradigma de máquina paralela virtual aplicado a ambientes distribuidos.O PVM-W95 (PVM para Windows95) é baseado na implementação original do PVM, constituindo um ambiente paralelo virtual que utiliza um conjunto de computadores pessoais, interligados por uma rede de comunicação, executando o sistema operacional Window395. O PVM-W95, embora apresente comportamento estável e permita que aplicações paralelas alcancem speedups favoráveis, demonstrou perdas de desempenho em avaliações preliminares, quando comparado com o PVM implementado para estações de trabalho UNIX.Este trabalho apresenta uma avaliação de desempenho minuciosa do PVM-W95, com o objetivo de identificar os motivos das perdas de desempenho verificadas inicialmente. A avaliação é realizada através da execução de benchmarks e da comparação do PVM-W95 com o PVM implementado para o sistema operacional LINUX (considerando a mesma plataforma de hardware).São apresentados os resultados obtidos com a avaliação de alguns protocolos com versões mais recentes e protocolos alternativos àqueles utilizados no PVM-W95.
