The integration of several codes to simulate physical processes or components of a nuclear energy facility facilitates large-scale, detailed simulation. However, integrated simulations require several weeks or months of CPU time. We developed a fault-tolerant method for cooperative execution of codes, which avoids unscheduled outage of computers or networks. The method deals with abnormal job terminations on supercomputers and file transfer errors. If a computer causes an unexpected outage, the method attempts to submit the simulation task to an alternative computer. The method also detects transfer errors by comparing the size of files before and after transfer. The relationship between jobs and file transfers is connected by the fault-tolerant method, which allows us to decide the execution order of codes by definition of file flow. This enables the operation on integrated simulations where codes are executed sequentially or concurrently.

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.
