I have been trying some simple code to write a file using Parallel I/O on
Open MPI. Here I specify the MPI_Info value as 0 and the execution
terminates with this messge for any number of processes:
*** An error occurred in MPI_File_open
*** on communicator MPI_COMM_WORLD
*** MPI_ERR_INFO: invalid info object
*** MPI_ERRORS_ARE_FATAL (your MPI job will now abort)
The src file is attached here .And im using openmpi-1.3.3a1r21566 build.
