Hi Matthew,
I just had the same problem with my application when using more than 4 cores -
however, the program didn't hang, it crashed, and I got an error message of
'address not mapped'. As you say, it happened different places in the code,
sometimes in the beginning, sometimes in the middle,
p the MPI handle as an
MPI_Comm all over your application.

Hi Jeff,
Thanks for your reply.
There are no core files associated with the cr
y where in MPI_Isend it failed -- like I said,
it's a short function that mainly checks parameters). You might want
to have your application double check all the parameters that are
passed to MPI_Isend, too.
