Seeking a Research Scientist or Postdoctoral Researcher (R-CCS1903)
RIKEN Center for Computational Science (R-CCS), led by Center Director Satoshi Matsuoka, is an international research center in high performance computing and computational science in Japan. Our objectives are to investigate “the Science of (high performance) computing, by computing, and for computing”, to research and develop our technologies (R-CCS technology) and software (R-CCS software), which we consider our core competence, in order to produce world-leading scientific and engineering results for use in Japan as well as globally.
Also, R-CCS started operating Japan’s national flagship supercomputer, the K computer, as a shared national facility to support a wide range of research activities in 2011. Following K’s success, development work on its successor, Supercomputer Fugaku, was launched in April 2014.
The Processor Research Team ("Processor team") conducts research to investigate and explore structural principles of new computing systems scalable even in the Post-Moore era, particularly, novel non-von-Neumann computer architectures and their programming methods where algorithms are mapped onto data-flow circuits.
Job title and job descriptions
One Research Scientist* or Postdoctoral Researcher
Conduct research regarding development of architecture evaluation environment and exploration of architecture design space as part of research contracted with New Energy and Industrial Technology Development Organization (NEDO). In the development of architecture evaluation environment, define design space of processor architectures suitable for vector data-flow processing including coarse-grain reconfigurable architecture (CGRA), and then develop emulators and/or evaluation environments required to analyze and evaluate performance characteristics of architectures with various configuration and parameters (You will take over what the former researcher developed so far). In the exploration of architecture design space, choose target applications and computational kernels, and then develop a tool set including a compiler to efficiently map them onto an architecture. With the tool set with the emulator and/or evaluation environment, explore the design space by evaluating various architecture configurations, and find appropriate architectures.
As necessary, conduct research in tight collaboration with other members of our team, other teams in R-CCS, other centers in RIKEN, and other collaborative partners in Japan and overseas.
Applicants must have a Ph.D. or expect to receive a Ph.D. before the date of appointment. In general, those who earned a doctorate within the past 5 years will be appointed as Postdoctoral Researchers, and those who earned a doctorate more than 5 years ago will be appointed as Research Scientists.
Processor team is interested in skilled and motivated applicants who have experience and knowledge in computer architectures based on data-flow computing, such like CGRAs, and their system software including compilers. Applicants with deep background of ordinary von-Neumann architectures, circuit design and implementation with FPGAs, and (event driven) processor simulation/emulation techniques are also considered with a great plus. Expertise with other related research areas is also considered. Excellent communication skill in English (or Japanese) is required.
