Abstract
A flexible intermediate library named Stampi for MPI-2 support on a heterogeneous computing environment has been implemented on an SCore cluster system. With the help of a flexible communication mechanism of this library, users can execute MPI functions without awareness of underlying communication mechanism. In message transfer of Stampi, a vendor-supplied MPI library and TCP sockets are used selectively among MPI processes. Introducing its own router process mechanism hides a complex network configuration in inter-machine data transfer. In addition, the MPI-2 extensions, dynamic process creation and MPI-I/O, are also available. We have evaluated primitive functions of Stampi and sufficient performance has been achieved and effectiveness of our flexible implementation has been confirmed.
