Hi, Manish,
The LAM version I am using is LAM 6.5.6.
The ROMIO is installed with the package LAM-runtime.
My test code is very brief:
#include <stdio.h>
#include "mpi.h"
#include "mpio.h"
int main(int argc,char **argv)
{
int me,ndata;
int dt;
MPI_File fh;
MPI_Init(&argc,&argv);
MPI_Comm_rank(MPI_COMM_WORLD,&me);
MPI_File_open(MPI_COMM_WORLD,"data",MPI_MODE_RDONLY,MPI_INFO_NULL,&fh);
MPI_File_seek(fh,me*1024,MPI_SEEK_SET);
MPI_File_read(fh,&dt,1,MPI_INT,MPI_STATUS_IGNORE);
MPI_File_close(&fh);
MPI_Finalize();
}
After Lamboot and compile successfully.
mpirun -np 4 ./filename
and the output is:
File locking failed in ADIOI_Set_lock. If the file system is NFS, you need
to use NFS version 3 and mount the directory with the 'noac' option (no
attribute caching).

-----------------------------------------------------------------------------
One of the processes started by mpirun has exited with a nonzero exit
code. This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.
PID 19462 failed on node n0 with exit status 1.
-----------------------------------------------------------------------------
p.s. I have mounted the NFS3 with "noac" option.
Thanks a lot!
