A New framework for integrated simulation model using MPMD approach

Takayama, Arimichi*; Shimizu, Katsuhiro; Tomita, Yukihiro*; Takizuka, Tomonori

We introduce a new effective framework to combine computer codes into integrated simulation model. The framework employs MPMD (Multiple Program Multiple Data) approach and each computer code is written with MPI (Message Passing Interface) library. Adopting MPMD approach makes each computer code independent, which leads to the capability for maintenance and improvement of the integrated simulation model. The validity and usability of this approach is shown through a simple example model, which simulates the integrated divertor code, SONIC.
