Seeking Researchers

Laboratory

High Performance Big Data Research Team
RIKEN Center for Computational Science
(Team Leader: Kento Sato)

Research Field

R-CCS (Director: Dr. Satoshi Matsuoka) is the organization which has two major functions, one for research and development of computational science and the other for operation of the K supercomputer. R-CCS cooperates with many research organizations of a wide-range of research fields, forms an international center for research and development, and plays the leading role of computational science in Japan. In R-CCS, computer science and computational science closely cooperate, and conducts research and development of common foundational nature for a wide range of fields in computational science, and also conducts research and development for high performance computing technologies.

The post-K computer development plan under the FLAGSHIP 2020 Project, initiated by the Ministry of Education, Culture, Sports, Science and Technology in 2014, has set the target of developing (1) the next generation flagship supercomputer of Japan (the successor of the K computer) along with (2) a wide range of applications that will address top priority social and scientific issues.

The High Performance Big Data Research Team leads research and software development for accelerating “machine learning, deep learning and large-scale big data processing (AI techniques)” on the K and the post-K supercomputers (HPC for AI). We also study for accelerating HPC applications and HPC systems by using these AI techniques. To tackle these research challenges, our team also study:

  • 1.Fast and scalable parallel I/O by taking advantage of next-generation memory (e.g., Non-volatile memory) in big data processing and machine learning;
  • 2.Scalable checkpointing for fault tolerance by taking advantage of next-generation memory (e.g., Non-volatile memory);
  • 3.Scalable algorithms for deeply-hieratical memory and storage architecture;
  • 4.Fast data transfer technique for multi-petabyte of big data on high-speed network;
  • 5.Integration of software stacks of bigdata, machine learning and HPC, and their optimization;
  • 6.Visualization and UI techniques of big data;
  • 7.Other research and software development related to big data, machine learning and I/O.

  • 5.Scalable techniques and algorithms for big data processing and machine learning
  • 6.Visualization of big data
  • 7.Publishing papers to top international conferences, releasing and promoting developed software

Qualifications

The position requires a Ph.D. (including those who will take a degree before arriving at the post. If it has been 5 years or less since your acquisition of Ph.D. degree, you will be employed as a Postdoctoral Researcher). The candidate also should have good experience of not only computer programming using C/C++ but also knowledge and experience on distributed systems and parallel programming (e.g., MPI, OpenMP or other parallel programming languages). It is preferable to have excellent experience and achievement on the offered topics above. Communication in English (or Japanese) is required.
