Looks like the attachment got stripped. Here's the code: $ cat test.c #include <mpi.h> #include <stdio.h>
int main(int argc, char** argv) { MPI_File handle; MPI_Info mpi_info = MPI_INFO_NULL; char fname[] = "/tmp/test.csv"; int amode = MPI_MODE_CREATE|MPI_MODE_WRONLY|MPI_MODE_UNIQUE_OPEN; int ierr;
MPI_Init(&argc, &argv);
ierr = MPI_File_open(MPI_COMM_WORLD, fname, amode, mpi_info, &handle); if (ierr != MPI_SUCCESS) { char err[MPI_MAX_ERROR_STRING]; int errlen; MPI_Error_string(ierr, err, &errlen); printf("%s\n", err); } else { MPI_File_close(&handle); } MPI_Finalize(); return 0; } /* END */
Thanks, Cihan

Hi list,
It appears there is a problem with the OpenMPI I/O library on CentOS 6.2 & 6.3 (package openmpi-1.5.4-1.el6.x86_64).
When I compile the attached program it ends up in the error path since MPI_File_open returns 16. The corresponding (unhelpful) message is: MPI_ERR_OTHER: known error not in list
I couldn't find any pointers on the net and the same program works with OpenMPI 1.4.5 on a debian system.
Any help would be greatly appreciated.
Cheers, Cihan
