G. Destri et P. Marenzoni, CELLULAR NEURAL NETWORKS AS A GENERAL MASSIVELY-PARALLEL COMPUTATIONAL PARADIGM, International journal of circuit theory and applications, 24(3), 1996, pp. 397-407
In this paper is presented the use of the discrete-time cellular neura
l network (DTCNN) paradigm to develop algorithms devised for general-p
urpose massively parallel processing (MPP) systems. This paradigm is d
efined in discrete N-dimensional spaces (lattices) and is characterize
d by the locality of the direct information transmission between the s
pace points (cells) and by continuous values of data and parameters; t
he DTCNN paradigm is thus able to express most of the;typical MPP appl
ications. A general version of a DTCNN has been implemented and optimi
zed for three MPP architectures, namely the Connection Machines CM-2 a
nd CM-5 and the Gray T3D. The comparison between the three machine per
formances with those achieved by a standard SPARC-20 workstation shows
that, particularly with large lattices, the speed-up allowed in the c
omputational times is significant and the range of solvable problem si
zes is widely extended.
