The MDAS consists of computers and its peripherals. The computers are classified with interactive data analysis servers, batch processing data analysis servers, terminal workstations, and remote login terminal computers. In the MDAS, the interactive data analysis servers are the main computer. Users access the interactive data analysis servers with SSH connection and analyze data on these servers. If necessary, users submit jobs to the batch processing data analysis servers from the interactive data analysis servers. The terminal workstations are located in the open-use room of the Subaru building and the room 101 of the ALMA building and the remote login terminal computers are located in the open-use room of the South building in the Mitaka campus. These computers are used for connecting to the interactive data analysis servers or light processing.
The MDAS is intended to be used for analytic research of astronomy data. Performing numerical computation and simulation using this system is not permitted. Those who want to do those researches need to use the computing system which Center for Computational Astrophysics (http://www.cfca.nao.ac.jp) employs.
