ROMIO Internals

A key component of ROMIO that enables such a portable MPI-IO implementation is an internal abstract I/O device layer called ADIO [5]. Most users of ROMIO will not need to deal with the ADIO layer at all. However, ADIO is useful to those who want to port ROMIO to some other file system. The ROMIO source code and the ADIO paper [5] will help you get started.

MPI-IO implementation issues are discussed in [6]. All ROMIO-related papers are available online at http://www.mcs.anl.gov/romio.
