Abstract

Kakuda Space Center is not only testing engines in ground facilities, but also simulating the engines. In order to maximize research and development products, technical engineers are working to maintain high performance visualizing terminals and software. Communication technology is also important for researchers in Kakuda Space Center that is located in long distance from Chofu JSS2. Kakuda Computer Center maintains hardware performance and technical skills to support researchers with increasing the quality levels on service requirement.

Goal

Supporting for JAXAsupercomputer Users in Kakuda Space Center

Objective

Technical supporting for researchers who carry out simulation analysis on JAXAsupercomputer in Kakuda Space Center.
