Hello netters!

I'm searching for any information on how to get a hopfield net parallelized
on a transputer-system. (32 T805's in a Multicluster 2 in this case.)

I know they can be parallelized "quite easily" using special hardware, but
with the four links of transputers the inter-node-communication appears to 
be a bottleneck for every "straightforward" implementation. But maybe we
missed some particular straightforward way? (The bottleneck does not seem to
become much wider if we use virtual links.)

I'd appreciate any pointers to literature, ftp-sites, articles, papers,
implementations, and so on that could help me with this task. Direct
recommendations on how to do it are very welcome too, of course.

I'm not really engaged in coding the network but I'm helping parallelizing
it. (So I'm no expert in neural nets/hopfield nets, but have experts at
hand, so feel free to mail answers difficult to understand.)

I'm definitely not able to switch hardware. (If other hardware would be
used the whole issue would not bother me.) That's why I'm posting to
comp.sys.transputer. (Additionally to posting to comp.ai.neural-nets.)

If possible, please reply per e-mail, I'll post a summary where I will also
include any reference I might find "outside usenet".

For those who might wonder - I've been among them little time ago:
A hopfield net is a special neural net often used for optimization.
