Handling large amounts of data and computations
Electronic infrastructure is essential for an increasing number of disciplines, and it is particularly important for research that requires demanding calculations, or generates large amounts of data. The project "Experimental Infrastructure for Exploration of Exascale Computing", or eX³, is a high performance computing project that develops competence and techniques for the coming generation supercomputers. Such exascale computers will be able to perform at a minimum of a billion billion (10^18) floating point operations per second. This new generation of high performance computing, which will be necessary to handle the exponentially increasing, complex data that is being generated in research and in applications, is a major target for international research.
Complex programming of exascale computers
There is still a stretch to go before the milestone of a billion billion operations per second is reached. This upcoming generation of computing will rely on an intricate interplay between thousands of sophisticated processing nodes, each with a large number of cores, deep memory hierarchies and equipped with accelerators, organized in complex communication topologies. The aggregated level of complexity in a system designed for billion-way concurrency represents a major challenge with many features: How to program such computers? How to port existing code, and how to reach a satisfactory level of reliability and efficiency while maintaining an acceptable energy footprint?
Keep pace with frontier research
While competing technologies in hardware, middleware, and software are being driven by major research projects in the United States, China, Japan and the EU, it is essential for Norwegian HPC research groups to keep pace with the frontier research. This means to build a strong competence on the upcoming exascale technology, thereby helping the entire Norwegian research community to be well prepared. Together with partners, Simula Research Laboratory proposes to establish eX³ with the aim of becoming exactly the previously missing national resource that can pave the way for exascale computing in Norway. The eX³project is designed to run for five years, funded by the RCN program for national research infrastructures. In addition to the host institution Simula, the project consortium also counts the national HPC management body Sigma2, HPC research groups from University of Tromsø and University of Bergen, and the multi-institutional research centers of excellence: SIRIUS, Big Insight, and Center for Cardiological Innovation), as well as the HPC technology providers Dolphin, Numascale, and Fabriscale.
