We have accomplished the GPU-acceleration of some key computations required by the CarMa code, used for the analysis of Resistive Wall Modes (RWM) in presence of three dimensional volumetric conductors. Significant accelerations (speed-up factors greater than 10) have been achieved on the computation of specific matrices of the overall model. This computational tool is used to study the effect of thick blanket modules on the n=0 RWM (axisymmetric vertical stability) for a scenario-4 ITER configuration.

Abstract
We have accomplished the GPU-acceleration of some key computations required by the CarMa code, used for the analysis of Resistive Wall Modes (RWM) in presence of three dimensional volumetric conductors. Significant accelerations (speed-up factors greater than 10) have been achieved on the computation of specific matrices of the overall model. This computational tool is used to study the effect of thick blanket modules on the n=0 RWM (axisymmetric vertical stability) for a scenario-4 ITER configuration.File in questo prodotto:
