About RIKEN AICSRIKEN is Japan’s largest comprehensive research institution, and is renowned for its
high-quality research in diverse range of scientific disciplines. The RIKEN Advanced
Institute for Computational Science (AICS), one of RIKEN’s centers, was founded in2010 with the objective of pioneering the new science of computer simulation-based
forecasting. To this end, AICS does the following;
Management of the operations of the K computer and maintenance of auser-friendly environment.
Promotion of collaborative projects with a focus on the disciplines ofcomputational science and computer science.

AICS Research Division
The AICS Research Division consists of 16 research teams and 3 research units. Its main tasks are;Promotion of K computer-based simulations in science and technology by developing more effective simulation
methods.
Development of methods for achieving more efficient operation of the K computer.
The Research Division brings together researchers specializing in computational and computer science to integrate and further
develop the two fields into what may eventually become a whole new field of interdisciplinary computational science, and tocontribute to the development of even more powerful supercomputers in the future.
