Hi,
I installed pvfs-2.6.2 on a 12 nodes cluster and it's working great.
Then I recompiled mpich2-1.0.5p3 with pvfs2 support following pvfs2
quick start guide ROMIO support section. MPICH2 is also working fine,
but when I tested pvfs2 accesses through MPI-IO, it keeps reporting the
following error, seems the the integration of ROMIO and pvfs2 is not
successful, but I don't know where I did wrong, can anyone help me
figure out this problem? thanks a lot.
x86-0$ mpiexec -n 1 my-mpi-io-test
0: MPI file open error.: File does not exist, error stack:
0: ADIO_RESOLVEFILETYPE_FNCALL(291): Invalid file name

my simple mpi-io testing code:
#include <stdio.h>
#include <mpi.h>
main(int argc, char **argv) {
int nprocs;
int myrank;
MPI_File mf;
int errcode;
char msg[MPI_MAX_ERROR_STRING];
int resultlen;
MPI_Init(&argc, &argv);
MPI_Comm_size(MPI_COMM_WORLD, &nprocs);
MPI_Comm_rank(MPI_COMM_WORLD, &myrank);
errcode = MPI_File_open(MPI_COMM_WORLD, "/mnt/pvfs2/tmp/test-mpi-io",
MPI_MODE_RDONLY, MPI_INFO_NULL, &mf);
if (errcode != MPI_SUCCESS) {
MPI_Error_string(errcode, msg, &resultlen);
fprintf(stderr, "%s: %s\n", "MPI file open error.", msg);
MPI_Abort(MPI_COMM_WORLD, 1);
}
MPI_File_close(&mf);
MPI_Finalize();
return 0;
}
thanks,
Yong
