Reasons for using JSS2

Inspection of the result of parallelisation of simulation tools, estimation of thier execution times, and the execution of the simulation tools

Achievements of the Year

It was found that the amount of memory required per process and the time required for process completion exceeded the limit of JSS 2 in the current calculation code. Therefore, we are studying ways to utilize computational resources of JSS2 by changing simulation method.
