An MPI library for heterogeneous computing environment, Stampi, has been implemented on an SCore cluster system to enable dynamic process creation defined in MPI-2 and MPI communication among multiple clusters. Objective of this implementation is realization of heterogeneous computing environment with an SCore PC cluster and other machines. Through performance measurement, sufficient performance has been achieved and effectiveness of our flexible implementation has been confirmed.

An MPI-2 based parallel-I/O library, Stampi-I/O, has been developed using flexible communication infrastructure. In Stampi-I/O almost all MPI-I/O functions have been implemented. We can execute these functions using both local and remote I/O operations with the same application program interface (API) based on MPI-2. In I/O operations using Stampi-I/O, users need not handle any differences in the communication mechanism of computers. We have evaluated performance for primitive functions in Stampi-I/O. Through this test, sufficient performance has been achieved and effectiveness of our flexible implementation has been confirmed.
