I understand that, and I checked the code to make sure the programmer didn't do anything stupid like that. The entire code is only a few hundred lines in two different files. In the entire program, there is only 1 include statement: include 'mpif.h' and MPI_STATUS_SIZE appears only once: integer ierr,istatus(MPI_STATUS_SIZE) I have limited knowledge of Fortran programming, but based on this, I don't see how MPI_STATUS_SIZE could be getting overwritten. -- Prentice
