Every process of the MPI application is client as well as server for I/O operations. This allows for a maximum of locality in file access, while the accesses to remote portions of the distributed file are performed via distributed shared memory techniques. A server is only required to manage the initial distribution of the file fragments between the participating nodes and to provide services like external access and redundancy.
