Silly me, after a couple of brain cycles I figured out how to use ints. I'll put some information up on the wiki about it. How about a conference call on Wednesday or Thursday morning say 11:00 EST? Although if another time works out better, I'll pretty free all week. Craig On Feb 15, 2008, at 1:56 PM, Craig E. Rasmussen wrote:

It would be easier to use ints (as we did in the paper). I just wasn't sure how to implement everything as ints using OpenMPI. Perhaps you could remind me how to do it. Ints would be preferable as I've already run into trouble with the current implementation attempt (see attached files) as the pointers are not compile time constants (and it seems that MPI_Recv is messing around with my datatype pointer).

Cheers, Craig
