在本文中，我们研究了细长位形的轴对称垂直不稳定性，包括体积三维导电结构周围的等离子体的影响。为了处理由真实感几何描述产生的巨大计算模型，追求基于GPU（图形处理单元）的加速。该方法被应用到一些ITER配置，其中的开环增长率，输入输出传递函数和增益和相位裕度的计算。
In this paper, we study the axisymmetric vertical instability of elongated configurations, including the effect of volumetric three-dimensional conducting structures surrounding the plasma. In order to deal with the huge computational models arising from the realistic geometrical description, a GPU-based (graphics processing units) acceleration is pursued. The method is applied to some ITER configurations, for which the open-loop growth rates, the input-output transfer functions and the gain and phase margins are computed.
