M. Reczko et al., A PARALLEL NEURAL-NETWORK SIMULATOR ON THE CONNECTION MACHINE CM-5, Computer applications in the biosciences, 11(3), 1995, pp. 309-315
Where present a parallel implementation of artificial neural networks
on the connection machine CM-5 and compare it with other parallel impl
ementations on SIMD and MIMD architectures. This parallel implementati
on was developed with tire goal of efficiency training large neural ne
tworks with huge training pattern sets for applications in molecular b
iology, in particular the prediction of coding regions in DNA sequence
s. The implementation uses training pattern parallelism and makes use
of the parallel I/O facilities of the CM-5 and its efficient reduction
operations available within the control network to achieve a high sca
lability. The parallel simulator obtains a maximum speed of 149.25 MCU
PS for training feedforward networks with backpropagation on a 512 pro
cessor CM-5 system without using the CM-5 vector facility. The impleme
ntation poses no restriction on the type of network topology and works
with different batch training algorithms like BP, Quickprop and Rprop
.
