[mpich-discuss] MPI_Barrier(MPI_COMM_WORLD) failed

[Xiao Bo Lu]

Hi,

Yes. It is a Fortran 90 code. I did re-compile all the source code and 
libraries with the new MPICH2. The cofiguration option I made is as:

./configure -prefix=/hpc/xlu012 CC=gcc F90=gfortran

and when I compiled all the files with the mpif90. I also did a few 
simple mpi tests with the mpiexec and it seems to work fine. I'm 
starting to wonder if there is anything to do with the memory allocation 
or some other communication variables that blocks some of the messages 
from a large array(??).

Regards
Xiao
