Well, this list isn't likely to help you (although it might -- a number
of us including myself play with GAs).  Google Is Your Friend (GIYF).
"genetic algorithm island model" yields dozens of obviously relevant
hits, including ones on parallel program design.  See e.g.

   http://citeseer.ist.psu.edu/corcoran94parallel.html

but this is just one of a LOT of hits.
