| Outline of Final Research Achievements |
Throughout this research project, we have conducted investigations regarding the interconnection network of massively parallel systems, such as supercomputers. We have especially focused on torus-based interconnects, and considered related theoretical problems such as routing algorithms and related graph theory problems. In addition, we have considered related practical problems, for instance thinking about how to reduce power consumption of interconnection networks since power consumption of modern supercomputers is an on-going issue. Concretely, we have investigated low-power devices and the corresponding technologies, and IoT devices in general to this end.

| Academic Significance and Societal Importance of the Research Achievements |
Modern supercomputers include numerous compute nodes, called processors. In order to maximise the system performance, it is critical to efficiently connect all these nodes as it conditions efficient data transfers and usage in general of the processors.
