Hi, Sorry about my previous message, it was sent before I'd finished composing it.
Whenever I use MPI_File_write_ordered(), all but one process send the following message to stderr. ADIOI_GEN_DELETE (line 22): **io No such file or directory I have read http://www.open-mpi.org/community/lists/users/2008/01/4936.php which suggests that this message appears because my program is trying to delete a file that does not exist, but my program does not explicitly delete any files. I've included a test program to demonstrate the message. Is there anything I can do to avoid or suppress this message? The message I referred to before says that I could "ignore errors from MPI_File_delete". How do I do that? Thanks, Brian int main( int argc, char *argv[]){ char buff[2] = "a"; MPI_File fh; MPI_Status status; MPI_Init( &argc, &argv ); MPI_File_open( MPI_COMM_WORLD, "foo.txt", MPI_MODE_CREATE | MPI_MODE_WRONLY, MPI_INFO_NULL, &fh ); MPI_File_write_ordered( fh, buff, 1, MPI_BYTE, &status ); MPI_File_close( &fh ); MPI_Finalize(); return 0; }//main
