Hi,
I did some testing and felt like giving some feeback. When I started this
discussion I compiled openmpi like that:
./configure --prefix=/home/toueg/openmpi CXX=g++ CC=gcc F77=gfortran
FC=gfortran *FLAGS="-m64 -fdefault-integer-8 -fdefault-real-8
-fdefault-double-8" FCFLAGS="-m64 -fdefault-inte

Hi,
I am using DRAGON, a neutronic simulation code in FORTRAN77 that has its own
datastructures. I added a module to send these data structures thanks to
MPI_SEND / MPI_RECEIVE, and everything worked perfectly for a while.
Then I had to raise the number of data structures to be sent up to a point
