Research Topic: Making InvisibleVisible: Visualization ofBubblesAppropriate visualization of calculation results is important, as it helps to achieve an intuitive understanding of physical phenomena and may even trigger the discovery of new phenomena. In large scale computing, however, the amount of data is enormous, making the data difficult to handle.Data formats that enable the data to be compressed without losing any vital information can be devised to make the data lighter and facilitate analysis and visualization. |

Research Topic: The Search for New Structures and Functions of Nanosize Molecules: Efficient Development of Massively Parallel Computing ProgramsA massively parallel quantum chemistry calculation program was developed and demonstration calculations were executed using a 100,000 CPU core of the K Computer. The achievement of high parallel performance and execution performance has made it possible to perform nanosize molecule calculations as routine work. In order to improve the efficiency of development in Field 2, preparations are underway to compile a library of calculations that can be shared and make it publicly available as an open source resource. |

Research Topic: Molecular Dynamics Calculations for the Methane Hydrate Decomposition ProcessAs dissociation of methane hydrate proceeds in liquid water, methane molecules are released into the surrounding area and bubbles are formed. Analysis conducted using the K Computer revealed that these methane bubbles accelerate the hydrate decomposition. This mechanism may be useful to utilize gas hydrates as an energy storage material. |
