The authors conducted a JHPCN adoption project "Development of large-scale data transfer technology between bases by fusing HPC and high-speed communication technology and system verification test using actual data" at each base via SINET / JGN, which are high-speed network backbone. L2VPN for high-speed data transfer and sharing between universities (Tohoku University, Tokyo University, Nagoya University, Kyoto University, and Kyushu University) and information infrastructure centers of research sites (Chiba University, Tsukuba University, Shinshu University, and NICT) The network service "JHPCN Wide Area Distributed Cloud" was constructed. High-resolution tile images (up to 5,500 x 5,500 pixels) for Himawari Real-time Web (https://himawari.asia) are stored in time varied order in the storage in the JHPCN Wide Area Distributed Cloud that can be accessed at high speed under the L2VPN environment. In addition, ChOWDER [1], an open source software is a web-based scalable display system that the authors are researching and developing that arranges multiple display devices (full-screen Web browsers) in tiles to display ultra-high-resolution contents that cannot be achieved with a single PC. It has a track record that point clouds of meteorological satellite Himawari cloud observation data and map data of the Geospatial Information Authority of Japan are superimposed and visualized in three dimensions on the ChOWDER display consisting of fifteen 4K resolution displays (total resolution: 19,200 x 6,480 pixels) [2]. In this presentation, we will introduce the results of an experiment that tiled displays with different resolutions at multiple sites (NICT: 23,040 x 10,800 total pixels, Chiba University: 17,280 x 4,800 total pixels, and Kyushu University: 15,360 x 6,480 total pixels) connected to the above-mentioned L2VPN network are displayed simultaneously at the maximum resolution of multiple Himawari's tile images via the ChOWDER server running at Kyoto University (Fig.1).
