Hi Vish,
Yes, mpi_file_sync will cause the server to fsync its data files. Just
to clarify, the PVFS clients never cache any data, so mpi_file_sync
doesn't have any effect on the client side. It just tells the servers
to flush their data.

Hi,
If we make a parallel application write to pvfs2 filesystem and perform a
mpi_file_sync in the client side, does it make sure that it does a sync in the
server side too? Or is there a special configuration to make it sync in the
server side?
Please let me know,
Thanks
Vish
