Abstract
Recently, there are many research with regard to model-based development(MBD) approach and degialization of space systems. JAXA Reserch Unit III is developing system simulator necessary for space system design in early phase, and it can be used to improve efficiency of development time. In this project, we will develop a method to run various MATLAB-based simulation in the satellite concept study phase ,especially large simulations such as parameter studies and Monte Carlo simulations, on JSS3.

Reasons and benefits of using JAXA Supercomputer System
All JAXA employee can use JSS quickly and easily without any complicated procedures.
The system can be connected within the JAXA intranet, so there is little risk of information leakage.
Quick access to extensive support on how to use the system.
Linux contaier technology can be applied.
Achievements of the Year
Results 1
Using MATLAB Parallel Computing Toolbox, a parallel computing method on multicore CPUs with Windows10 Virtual Machine on JSS3 TOKI-RURI is developed. As a trial, a Monte Carlo simulation analysis model of a spacecraft was run in parallel, and it was confirmed that the Simulink model could be calculated about 22 times faster than the conventional method.
Results 2
Using MATLAB Compiler and Simulink Compiler, a method to implement the calculation of various MATLAB simulation models as a standalone application that runs in a Docker container is developed. In addition, the Docker container can be converted into a Singularity container running on JSS3, and confirmed that MATLAB model calculations could be realized in 50 parallel by batch jobs on JSS3 TOKI-RURI.
