Abstract of SMARTEST Project

The SMARDDA (pronounced ‘smarter') software consists of a set of Object-oriented Fortran modules developed at Culham primarily for physics models involving particle and surface interactions. Most notable of these is calculation of power deposition on tokamak plasma facing components (PFCs) to verify and help develop PFC surface designs. The importance of the code is underlined by the funding by ITER of the SMITER PFC analysis tool, for which SMARDDA forms the computational kernel. The SMARDDA modules have only been selectively optimised for JET PFC calculation, and both memory allocation and speed limitations have emerged in application to JET DT campaign, ITER and reactor PFC design that need addressing. Overcoming these limitations will also enable use of the modules in conjunction with Monte Carlo techniques, in intershot analysis and ultimately in real-time control. The former will permit treatment of more complex physical effects involving large number's of particle collisions, and the use of ensembles to quantify uncertainties in power deposition due to misalignments or errors in equilibrium magnetic field. The SMARDDA modules will be refactored and in some cases redesigned with new numerical techniques to exploit the Intel Xeon Phi architecture. This will not only enhance current PFC modelling capabilities (SMITER application) but will extend the range of physics applications of the code.
