Offer Description

[Background of the recruitment and description of the project]
* Background of the recruitment and description of the project
[Research field]
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 utilizes its expertise to operate the supercomputer Fugaku, developed as Japan’s national project, in accordance with relevant ordinances.

The Quantum-HPC Hybrid Platform Division (Quantum-HPC PF Div. ) was established on April 1, 2023. We aim to design and develop a Quantum-HPC Hybrid platform, which will serve as a new computational infrastructure to extend the computable domain by highly linking a Quantum Computer (QC) and a supercomputer (HPC). The missions of the Quantum-HPC PF Div. include the development of software stacks required to realize the Quantum-HPC Hybrid platform and the improvement of the platform's usage environment.

The Quantum-HPC PF Div. has three units:
1)Quantum-HPC Hybrid Software Environment Unit
2)Quantum Computing Simulation Unit
3)Quantum-HPC Hybrid Platform Operations Unit

The Quantum-HPC Hybrid Platform Operations Unit shall develop and operate the environment of the quantum HPC platform. It will also develop and upgrade the usage environment to promote common use of both for users.

RIKEN is Japan's largest and most comprehensive research organization for basic and applied science.

[Work content and job description]
In accordance with the research project of NEDO “Research and Development of Quantum-Supercomputer Hybrid Computing Platform for Exploring Computable Regions” (PI: Mitsuhisa Sato (RIKEN), Research Period: November 2023 – October 2028), we will develop and operate the environment of the“Quantum-HPC Hybrid platform”. In addition, we will develop and upgrade the usage environment to promote common usage of both for users. Specific research and development themes are expected to include the following.

・Development of a data center environment for introducing a quantum computer (QC) and researching and developing a hybrid environment with a supercomputer (HPC).
・Development and operation of a system to connect the quantum computer (QC) and the HPC system, including the supercomputer Fugaku via a high-performance network and to collaborate them at a high level.
・Development and operation of a system that enables concurrent use of the quantum computer and HPC systems connected by a wide-area network.
・Developing and operating a user management system to promote using the QC and HPC collaborative environment.
・Development and maintenance of a system and software environment that enables existing HPC users to use the quantum computer without problems.
・Design a system to make QC and related systems available to RIKEN, associated projects, and the general public.

They are also expected to contribute to the management of the department. In particular, the Senior Technical Scientist is expected to assist the Unit Leader, play a leadership role within the Unit, and make a significant contribution to the department and unit operations.
