A flexible intermediate library named Stampi realizes seamless MPI operations on a heterogeneous computing environment. With the help of a flexible communication mechanism of this library, users can execute MPI functions without awareness of underlying communication mechanism. Although Stampi supports MPI-I/O among different platforms, UNIX I/O functions are used when a vendor-supplied MPI-I/O library is not available. To realize distributed I/O operations, a Parallel Virtual File System (PVFS) has been implemented in the MPI-I/O mechanism. Primitive MPI-I/O functions of Stampi have been evaluated and sufficient performance has been achieved.
