[CentOS] OpenMPI I/O not working
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 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] OpenMPI I/O not working
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

Hello again, I dug a bit deeper and found that the default IO component (romio) is not built due to an autoconf issue I don't understand. It looks like some macros in ompi/mca/io/romio/romio/configure are not expanded/substituted.
