Hi All:
I have a small cluster running a remote sensing code. 
I'm using MPICH on top of Mac OS X.
Right now, my parallel performance isn't so great,
because my communication time is far outweighing my
computations.
Does anybody have experience/suggestions/lessons
learned about using the various MPI-IO routines???
I'm particularly interesting in learning more about
successful use of the non-blocking read and write
calls.
Any pointers to sample codes would be greatly
appreciated!
THANXS!
