Reasons and benefits of using JAXA Supercomputer System

It is available immediately after application

Achievements of the Year

Plasma numerical analysis and flow analysis of neutral particles in electric propulsion were performed. The number of parallel processing was performed by a method using MPI with 20 processes per node. This year, the main focus was on code tuning.
