Easy use of high performance computers for fusion simulations

Fusion Modelling and Simulation are very challenging and the high performance computing issues are addressed here. Based on the framework developed by the European Integrated Tokamak Modelling project and on the EUFORIA infrastructure, a tool solving nicely these difficulties has been developed for the end users and applied to several fusion simulation cases. The first part recalls the issues with GRID and high performance computing, while the second part presents the solutions and the tool for developing easily a GRID/HPC actor. The last part reports the use of this tool in MHD equilibrium and plasma edge simulations.

► We developed a software tool that converts a physics code to a Kepler actor.
► The actor runs the codes on a remote supercomputer or a grid.
► The complexity is hidden from the user.
► We present the first workflows that use actors generated by the proposed tool.
