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.

SCore system has been developed to provide flat computing infrastructure for parallel computing without awareness of each compute host in a PC cluster system. An SCore cluster system can be handled as a single computer. MPICH-SCore, which is an MPI library in SCore, is not available across multiple SCore cluster systems as well as multiple platforms. We have implemented an MPI communication library, Stampi in SCore cluster system to enable MPI communication between SCore cluster systems and measured communication performance of the library using SCore cluster systems.
