There's nothing that says that your daemons have to be MPI processes. They
could be proper system-level daemons that live "forever", for example. You
might not be able to speak to them via MPI easily (e.g., you may need to use
TCP sockets or some other network transport), but this is fairly co

One flaw in the idea: the daemons are not MPI processes, and therefore
One flaw in the idea: the daemons are not MPI processes, and therefore have no
way to run an MPI I/O operation.

Hi,
I have an idea about using database to support a kind of semi-automatic
optimized parallel I/O operations and want to know if it is realizable or not.
Hope you guys can give me more advices and point out the shortage of the idea.
Thank you all.
As the performance of the parallel I/O depend
