Scalability of Enhanced Parallel Batch Pattern BP Training Algorithm on General-Purpose Supercomputers

The development of an enhanced parallel algorithm for batch pattern training of a multilayer perceptron with the back propagation training algorithm and the research of its efficiency on general-purpose parallel computers are presented in this paper. An algorithmic description of the parallel version of the batch pattern training method is described. Several technical solutions which lead to enhancement of the parallelization efficiency of the algorithm are discussed. The efficiency of parallelization of the developed algorithm is investigated by progressively increasing the dimension of the parallelized problem on two generalpurpose parallel computers. The results of the experimental researches show that (i) the enhanced version of the parallel algorithm is scalable and provides better parallelization efficiency than the old implementation; (ii) the parallelization efficiency of the algorithm is high enough for an efficient use of this algorithm on general-purpose parallel computers available within modern computational grids.
