N2 - A fully connected feedforward neural network is simulated on a number of parallel computers (MasPar-1, Connection Machine CM5, Intel iPSC-2 and iPSC-860) and the performance is compared to that obtained on sequential vector computers (Cray YMP, Cray C90, IBM-3090) and to a scaler workstation (IBM RISC-6000). Peak performances of up to 342 million connections per second (MCPS) could be obtained on the Cray C90 using a single processor while the optimum performance obtained on the parallel computers was 90 MCPS using 4096 processors. Efficiency such as these has enabled neural network computations to be carried out for a number of chemical physics problems. Several examples are discussed: multi-dimensional function/surface fitting, coordinate transformations, and predictions of physical properties from chemical structure.
