You cannot tell from just the channels information which processes should go
together. It is a matter of how much processing time they need, and to what
extent the processes are interdependent for their data.

As for configuring the program for 2 transputers, I think you will need to
study the manuals very carefully. I know they are not much fun and not really
very well written, but spending some time on studying them does make some
basic things clearer. A faster method would be for your company to hire me
to give you a training, but that would probably be outside your budget.

OK, I hope this was useful for you, anyway.

Good luck !
