Hi Dries,

Ok I understood your original question differently, but anyway, yes I 
can create a library on top of MPI to do what you mentioned. I don't see 
why, for this case, it is better.. A lot of the information that is 
needed to determine whether an operation depends on the progress of 
another is present in the MPI library. Doing the same thing again at a 
higher layer (i.e. decoding datatypes, hand out generalized requests, 
etc..) isn't very encouraging.

I agree with you there..
