Jan. 29: Towards Next Generation Chinese Supercomputer
Speaker: Dr. Yutong Lu (GZSC)
In the post-petascale and exascale era, the innovative integrated technologies are needed from new architecture to associated software stacks. We must deal with the performance, scalability, power consumption and reliability issues. The system hardware and software stack co-design needs to explore the capability of cpu, accelerator, interconnection, I/O storage system, and till whole system. This talk will also cover the efforts and experiences from China, especially NUDT to design and implement the Tianhe serial systems and applications. The domain-specific application platforms have been building to help broader users moving forward efficiently to next generation large-scale computing.
Yutong Lu, holds Professor position both in Sun Yat-sen University(SYSU) and National University of Defense Technology (NUDT), she is Director of National supercomputing center in Guangzhou. She is a member of Chinese national key R&D project HPC special expert committee. She got her B.S, M.S, and PhD degrees from the NUDT. Her extensive research and development experience has spanned several generations of domestic supercomputers in China, she is deputy chief designer of Tianhe-2 system. Her continuing research interests include parallel operating system (OS), high speed communications, global file systems, and advanced programming environments converging HPC and bigdata.
Jan. 30: Issue and Solutions for Extreme Scale Computing
Speaker: Prof. Jack Dongarra (University of Tennessee)
Jan. 31: An Overview of Post-K Development
Speaker: Dr. Yutaka Ishikawa (RIKEN AICS)
The next flagship supercomputer in Japan, replacement of the K supercomputer and thus we call it post-K computer, is being designed to be operated in early 2020s. Its node architecture and interconnect are an ARM HPC extension and a 6-D mesh/torus network, respectively. A three level hierarchical storage system will be installed with compute nodes. The system software developed in the post K supercomputer includes a novel operating system for general-purpose manycore architectures, low-level communication and MPI libraries, and file I/O middleware. After introducing an overview of the post K architecture, the current status of the system software development and activities of international collaborations will be presented.
Project Leader of Exascale Computing and Leader of System Software Development, RIKEN AICS
Visiting Researcher, University of Tokyo
Yutaka Ishikawa is in charge of developing the Post-K computer. Ishikawa received the BS, MS, and PhD degrees in electrical engineering from Keio University. From 1987 to 2001, he was a member of AIST (former Electrotechnical Laboratory), METI. From 1993 to 2001, he was the chief of Parallel and Distributed System Software Laboratory at Real World Computing Partnership. He led development of cluster system software called SCore, which was used in several large PC cluster systems around 2004. From 2002 to 2014, he was a professor at the University Tokyo. He led the project to design a commodity-based supercomputer called T2K open supercomputer. As a result, three universities, Tsukuba, Tokyo, and Kyoto, obtained each supercomputer based on the specification.
