Guest Speaker: Dr. Keichi Takahashi visited the ACIS lab in Larsen Hall during the week of November 11th, 2019 to discuss collaborative research with ACIS faulty and student. Dr. Takahashi was also the guest speaker on Data movement middleware towards exascale high-performance computing.
Abstract: In this talk, he presented how storage I/O is becoming a critical bottleneck in current and future high-performance computing systems, along with different approaches to mitigate the I/O bottleneck problem. In particular, he focused on in-situ analysis and visualization, which are techniques to bypass storage I/O and directly couple simulation and post-processing applications together. He presented how in-situ visualization is helping JAXA (Japanese space agency) scientists to simulate and analyze the aeroacoustic load during rocket launch.
About: Dr. Takahashi is an assistant professor at Nara Institute of Science and Technology (NAIST), where he is a member of the Software Design and Analysis Laboratory. He also serves as a guest faculty at Cybermedia Center, Osaka University.
Dr. Takahashi received his Ph.D. in Information Science in 2019 at Osaka University, where he worked under the supervision of Prof. Shinji Shimojo and Assoc. Prof. Susumu Date. Before starting his Ph.D. program, he received his Master’s degree in Information Science and Bachelor’s degree in Electronic and Information Engineering at Osaka University.
His research mainly focuses on middleware for high-performance computing. In particular, he studies how to create software for efficiently moving data inside a compute node, between compute nodes and from/to persistent storage on a large-scale high-performance computing system.
In addition to his academic work, he has been working as a professional software engineer. He has designed and developed a wide variety of software, including image analysis, signal processing, factory automation, desktop, and web applications.
