Key Features

In the Software Design & Analysis Laboratory, we conduct research on the methods and technologies which support the design / development of software and cloud computing systems. Our main focus is on the analysis and improvement of the software development process. Software technology is increasingly present in our daily lives, including various software embedded machinery and electronic devices for homes or mobile telephones and social infrastructures represented by cloud computing systems.

Research Equipment

We maintain a private cloud system for software analysis and cloud computing research integrated with a virtualization platform. This system comprises 47TiB of ultra high-speed and reliable network storage and a cluster of blade servers equipped with a total of 128 CPU cores and 576GiB of RAM. We have access to multiple leadership-class supercomputers, including USA's Summit and Japan's ABCI and Flow, for HPC research.
