Hi RobL,
Hi Murali. I think for ROMIO we want the file system to get out of the way. ROMIO can exploit MPI-IO semantics to do reasonable caching on its own. Ok, we don't do this now, but it's possible. As long as it's easy for ROMIO to turn off any "help" from the underlying file system, we'll be ok.
I agree. I just don't want bugs to show in mpi-io/netcdf programs if they are run through the vfs interface of pvfs2.. that's my only concern :) Thanks, Murali
