Yuka Narushima, a second-year graduate student in the Department of Science and Engineering, 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), in conjunction with the Information Processing Society of Japan (IPSJ), at the "Information Science and Technology Forum." The forum is held to gather and disseminate the latest information on information science and technology and to facilitate exchange among researchers. During each general presentation session, the chair selects one outstanding presentation to receive this award.
In the high-performance computing session of the "Software" category, Mr. Narushima proposed a method for high-speed computation of computer-generated holograms (CGH) using a heterogeneous multi-GPU cluster system composed of different GPUs (*1), with the aim of effectively utilizing existing computing resources.By distributing the computational load of CGH calculations to match the performance of the GPUs, he succeeded in generating 30 frames per second of CGH derived from a three-dimensional object composed of approximately 800,000 points, thereby successfully projecting the three-dimensional object as an image in mid-air. His outstanding computational performance was highly praised, leading to this award.
Presentation Title: Real-Time Electronic Holography Using a Heterogeneous Multi-GPU Cluster System
Presenters: Yuka Narushima, Hisanaga Mitani, Shomu Wada, Naoki Takada (Kochi University)
*1 GPU: A processing unit that performs the calculations required to render 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 reflected from a three-dimensional object and the original incident light. By shining light onto this interference pattern, it is possible to faithfully reproduce the three-dimensional object as an image.
