High Performance Computing

Raijin supercomputer

Imagine a large computer system that fails. One of the power supply units shuts down or a memory slip causes data to become corrupted. The computer might continue to operate, but it produces the wrong answer to an important question—this could be catastrophic in the case of tsunami prediction. Welcome to the realm of high-performance computing.

One of the main objectives of our research is to support large-scale scientific simulations, including highly accurate weather forecasting, flood modelling and nuclear fusion simulation. We write codes so that processors run efficiently both in terms of speed and energy consumption. We develop algorithms and run-time systems so these simulations are reliable even under system failures. We are also investigating innovative design processors for supercomputers.

Our work is motivated primarily by specific problems, and we work independently and collaboratively with other academic, industry and government organisations from Australia, the United States, China and Germany to solve them.
