Project Status: Active
The goal of this project is to develop a high-fidelity whole device model (WDM) of magnetically confined fusion plasmas, which is urgently needed to understand and predict the performance of ITER and future next-step facilities, validated on present tokamak experiments. Guided by the understanding obtained from several fusion experiments as well as theory and simulation activities in the USA and abroad, ITER is expected to attain ten-fold energy gain and will realize burning plasmas that can be well beyond the operational regimes accessible in present and past fusion experiments. The science of fusion plasmas is inherently multi-scale in space and time, spanning several orders of magnitude in a geometrically complex configuration, and is an ideal testbed for extreme-scale computing.
This is a large, interdisciplinary, multi-institution collaboration led by Amitava Bhattacharjee from Princeton Plasma Physics Laboratory. Oak Ridge's contributions are the code coupling framework, EFFIS 2.0, that enables the runtime environment for the simulation environment, numerous services for online, in situ reduction, analysis, or visualization of the data that are integrated into EFFIS 2.0, and expertise in performance measurement and tuning of the codes.
