Seeking a Research Scientist or Postdoctoral Researcher (R-CCS2105)
The RIKEN Center for Computational Science (R-CCS), led by Center Director Satoshi Matsuoka, is an international hub for computational science that promotes “science of computing, by computing, and for computing.” R-CSS positions the technology in which RIKEN has strengths (R-CCS technology) and the software developed by RIKEN that contributes to science, technology, industry, and society (R-CCS software) as its “core competence in computational science driving science as a whole.” R-CCS aims to develop these technologies, disseminate them domestically and internationally, and produce results. In addition, R-CCS is utilizing its expertise to operate the supercomputer “Fugaku” which was developed as a national project in accordance with Japanese laws and regulations.
The Processor Research Team ("Processor team") conducts research to investigate and explore organization principles of new processors and/or computing systems which are appropriate in the Post-Moore era, particularly, novel non-von-Neumann processor architectures and their programming methods where algorithms are mapped onto data-flow circuits.
Job title and job descriptions
Job title, available positions
Research Scientist or Postdoctoral Researcher: a few positions
Conduct research regarding processors, computing systems, programing models, and/or system software such as a compiler based on architectures different from conventional many-core processors, especially, novel processor architectures suitable for vector data-flow processing including coarse-grain reconfigurable architectures (CGRAs).
As necessary, conduct research in tight collaboration with other members of our team, other teams in R-CCS and RIKEN, and other collaborative partners of academia and industries in Japan and overseas.
In addition to the above research and development, take charge of various tasks in Processor team and R-CCS.
Applicants must have a doctor degree (or are expected to have a doctor degree 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 expertise and knowledges in computer architectures, processor designs, or system software such as compilers. Applicants with deep background, experience, and skills of the above R&D are also considered with a great plus. Expertise with conventional von-Neumann processor architectures and their compilers, and other related research areas is also considered. Excellent communication skill in English is required. Such applicants are desired, who are proactive in exploring and expanding research themes by themselves.
