H( i :OE i ) H( i : p ij ) H( i j :p ij ) consequentemente: E = i H( j :p ij ) Sistemas de inferencia baseados em modelos conexionistas surgem como uma alternativa ao processamento paralelo de inferencia que at e ent ao tem sido pesquisado para modelos de arquitetura convencionais [20, 21, 4, 5, 6, 17, 16, 11]. A rede de neuronios implementando um sistema de inferencia representa um conjunto de regras que devem ser satisfeitas a partir de uma entrada do tipo consulta a um banco de dados, por exemplo. Novos valores (sinais) para os n os da rede s ao calculados atrav es de uma equac ao matem atica que ....

....been developed for bus based shared memory architectures. Their complexity and the large amount of data they process raise the question of whether PLP systems can still obtain good performance on scalable architectures, such as hardware distributed shared memory (DSM) systems. Our previous work [16, 15, 17] has shown that PLP systems as originally implemented do not perform well on scalable DSM multiprocessors; PLP systems only perform well for these machines when heavily modified to improve locality of reference. We focused on Andorra I [18] a PLP system capable of exploiting implicit parallelism ....

....system, since most of its data structures are similar to the ones of several other PLP systems. Andorra I has obtained good performance on the Sequent Symmetry, but our experience with it running on modern multiprocessors demonstrates indeed that scalability suffers greatly on these architectures [7]. This paper addresses the question of whether the poor scalability of Andorra I is inherent to the complex structure of PLP systems or can be improved through careful analysis and tuning. In order to answer this question, we analyse the cache behaviour of all Andorra I data areas when applied to ....
