Profile
Biography
Rio Yokota is a Professor at the Supercomputing Research Center, Institute of Integrated Research, Institute of Science Tokyo. He also leads the AI for Science Foundation Model Research Team at RIKEN Center for Computational Science. His research interests lie at the intersection of high performance computing, machine learning, and linear algebra. He has been optimizing algorithms on GPUs since 2007, and was part of a team that received the Gordon Bell prize in 2009 using the first GPU supercomputer. More recently, he has been leading distributed training efforts on Japanese supercomputers such as ABCI, TSUBAME, and Fugaku. He is the co-developer of the Japanese LLM Swallow, and LLM-jp. He is also involved in the organization of multinational collaborations such as ADAC and TPC.
