GRAD-CM2: A Data-Parallel Connectionist Network Simulator

A data-parallel simulator capable of training recurrent time-delay connectionist networks is described. The simulator, GRAD-CM2, is written in the C* programming language and runs on a Connection Machine CM-2. GRAD-CM2 is an extension of the serial simulator, GRADSIM [8], and offers similar features. Timing performances of GRAD-CM2 and GRADSIM on a series of spatiotemporal discrimination tasks are presented to emphasize the efficacy of data-parallelism.
