\section{Installation Instructions}
Since ROMIO is included in MPICH, LAM, HP MPI, SGI MPI, and NEC MPI, you don't
need to install it separately if you are using any of these MPI
implementations. If you are using some other MPI, you

\item All nonblocking I/O functions use a ROMIO-defined {\tt MPIO\_Request}
object instead of the usual {\tt MPI\_Request} object. Accordingly, two
functions, {\tt MPIO\_Test} and {\tt MPIO\_Wait}, are provided to test
and wait on these {\tt MPIO\_Request} objects. They have the same
