Cyberscience Center was founded as a national supercomputer center hosted by Tohoku University in 1969. Since then, the Center has been installing high-end computing systems and providing them to researchers and students nationwide in Japan. In addition to the role of a national inter-university joint usage/research center for high performance computing, the Center is responsible for cyber-infrastructure of the University.

This year we have installed a new system, AOBA.

AOBA System Information

The world's first system of the second-generation SX-Aurora TSUBASA


AOBA consists of AOBA-A and AOBA-B.

Research Projects

We focus on the design and development of high-performance supercomputing systems and their applications. Since it is necessary to well understand and exploit the parallelism of the underlying hardware for high performance, we are developing programming models and supportive tools to facilitate the parallel programming and code optimization. In addition, as supercomputer systems are becoming larger and more complicated, its power consumption and dependability become critical design constraints of supercomputers. Therefore, we are designing/architecting the next generation supercomputers with high power efficiency and dependability.

Application Development
Working together with application developers to achieve high performance.
Machine Learning for HPC
Performance-aware programming assisted by machine learning.
HPC Programming Framework
Application development is a teamwork of different kinds of programmers.
QA for Combinatorial Problems
Making a good use of emerging devices for HPC.
Heterogeneous Computing
Programming with assigning right tasks to right processors.
Task Mapping and Scheduling
Intelligent resource management for highly efficient computing.
Tsunami Inundation Simulation
Predicting damage from a tsunami immediately after the earthquake.
Memory Architecture Design
Integrating large and fast memories into a single system.
Code Optimization and Tuning
