The Center for Plasma Edge Simulation (CPES) is a recently funded prototype Fusion Simulation Project, which is part of the DOE SciDAC program. Our center is developing a novel integrated predictive plasma edge simulation framework, which is applicable to existing magnetic fusion facilities (D3D, NSTX, CMOD) and next generation burning plasma experiments, e.g. ITER. The success of this project will be in developing and understanding new models for the plasma edge in a kinetic regime with complex geometry. Because of the multi-scale nature of the problem, we will study the neoclassical physics time scale kinetically, and the fast and larger scale MHD modes via a fluid code. Our approach is to couple these codes via a scientific workflow system, Kepler-HPC. Kepler-HPC will enhance Kepler with capabilities such as code coupling and data redistribution, high volume data transfers and interactive (and autonomic) monitoring, steering and debugging, which will be necessary for scientific progress in this project.
