| Research Abstract |
A middleware system called a Mediator ver.2(Med2) has been developed which provides high-level transparency in transferring and transforming data between heterogeneous application components. The Med2 focuses on a data-handling specification that correlates different discrete points in FDM, FEM, and particle simulations. It supports a variety of techniques for semantically transforming the physical values associated with the correlated points.
To facilitate easier usage and minimize customization of original programs, the Med2 provides two types of API, which (1) construct association between Med2 processes and application processes in SPMD and Master-Worker, (2) register different kinds of discrete points, search the correlated discrete points and determine processes with which communication is required. The prototype system has been applied to particle-mesh coupled simulation and OpenFMO program.
