Simple Orchestration Application Framework to Control 'Burning Plasma Integrated Code'

摘要

We have developed the Simple Orchestration Application Framework (SOAF) on a grid infrastructure to control cooperative and multiple execution of simulation codes on remote computers from a client PC. SOAF enables researchers to generate a scenario of their cooperative and multiple executions by only describing a configuration file which includes the information of execution codes and file flows among them. SOAF does not need substantial modification of the simulation codes. We have applied SOAF to the "Burning Plasma Integrated Code" which consists of various plasma simulation codes. In order to predict and interpret the behavior of fusion burning plasma, it is necessary to cooperatively and concurrently execute various simulation codes to understand complex plasma phenomena with wide temporal and spatial ranges. Those codes exist on distributed heterogeneous computers located in different sites such as universities and institutes. By using SOAF, we succeeded to cooperatively and concurrently execute four plasma simulation codes without substantial modification as described in the configuration file.
