Hi.<br><br>I attached the test result of 'src'mpi/romio/'. It seems that the failed tests are related with the shared file pointer and ordered mode. This time, I used gfortran-4.3 for the Fortran compiler(i.e. F77=/usr/bin/gfortran FC=/usr/bin/gfortran ./configure --with-file-system="pvfs2+nfs+ufs"). Other configurations are the same.<br>

There are some MPI-IO features that are not supported on PVFS:<br>
- Shared file pointers requre explicit file locks, which PVFS does not<br>
suport<br>
- Orderd mode also relies on the shared file pointer, so that's not<br>
supported either<br>
<br>
Can you try out the tests in 'src/mpi/romio' ? you can just do a<br>
"runtests -fname=/pvfs/whatever"<br>
<br>
For the async I/O test we might have to get the orangefs guys<br>
involved.<br>
