I'd be interested to know of other responses as my experience closely
mirrors yours. I used graphcode and classdesc(it is on sourceforge) to
achieve the sharing of a graph in an MPI environment. Classdesc handles
all the packing for transfer of linked lists. Graphcode looks after the
distribution of the objects.
Now for the catches.
1) it is c++ not c
2) I know the guy who wrote graphcode (he is now on long service leave)
3) I too am/was a novice programmer given code to make parallel and it has
taken me about a year to get my head around all this lot.
I hope this helps. I can give you some more information of graphcode
should you want. Just fire me an email.
