摘要
描述了HL-2A等离子体实时平衡重建的GPU并行化算法,主要包括G-S方程的并行化处理、三对角方程求解、网格边界磁通计算以及一系列矩阵相乘的并行加速。并行后,在129×129的网格下完成一次迭代计算需要约575μs。
The GPU parallel algorithms of the HL-2A plasma real-time equilibrium reconstruction including parallel processing of G-S equati6n, an algorithm solving the tri-diagonal linear system efficiently in parallel, the computation of the flux on grid boundary points and some parallel speed-up for middle-scale matrix multiplication on GPU, were intoduced. After the parallelization, an equilibrium reconstruction iteration needs around 575kts with a 129-129 grid.
