Hi List,
I am learning MPI.
A small code snippet try to open a file by MPI_File_open gets error
16(Internal error code.) in a single server with OpenMPI 1.3.3, but
it's run correctly in another server(with OpenMPI 1.3.2).
How to fix this problem? Thanks.
This is the snippet:
int main(int argc, char *argv[]) {
MPI_File fh;
MPI_Init( &argc, &argv );
int ret = MPI_File_open(
MPI_COMM_WORLD, "temp",
MPI_MODE_RDWR | MPI_MODE_CREATE,
MPI_INFO_NULL, &fh);
if (ret != MPI_SUCCESS) {
fprintf(stderr, "open file failed, code=%d\n", ret);
} else {
MPI_File_close(&fh);
}
MPI_Finalize();
return 0;
}
