Graduate SchoolScience and Technology ProgramYuka Narushima, a sophomore, received the FIT Encouragement Award at the 22nd Information Science and Technology Forum (FIT2023).
This award is presented by the Information and Systems Society and the Human Communication Group of the Institute of Electronics, Information and Communication Engineers (IEICE), together with the Information Processing Society of Japan (IPSJ), at the “Information Science and Technology Forum”—an event organized to gather and disseminate the latest information on information science and technology and to facilitate exchange among researchers. During each general presentation session at the forum, the session chair selects one outstanding presentation to receive the award.
During the high-performance computing session in “Field B: Software,” Mr. Narushima proposed a method for high-speed computation of computer-generated holograms (CGH) (Note 3) using a heterogeneous multi-GPU cluster system (Note 2) composed of different GPUs (Note 1), with the aim of effectively utilizing existing computing resources.By distributing the CGH computational load according to the performance of each GPU, he succeeded in calculating 30 frames per second of CGH generated from a three-dimensional object consisting of approximately 800,000 points, thereby successfully rendering the three-dimensional object as an image in mid-air. His work was highly praised for its outstanding computational performance, which led to this award.
Presentation Title: Real-Time Electronic Holography Using a Heterogeneous Multi-GPU Cluster System
Presenters: Yuka Narushima, Hisashi Mitani, Shomu Wada, Naoki Takada (Kochi University)
*1 GPU: A processing unit that performs the calculations necessary for rendering images, including 3D graphics.
*2 Heterogeneous multi-GPU cluster system: A system consisting of multiple computers, each equipped with GPUs of varying computational performance, connected via a network.
*3 Computer-Generated Hologram (CGH): A two-dimensional interference pattern created by a computer that simulates the interference phenomenon resulting from the interaction between light incident on a three-dimensional object and the light reflected from it. By shining light onto this interference pattern, it is possible to faithfully reproduce the three-dimensional object as an image.
