针对不完全Cholesky共轭梯度(ICCG)问题，提出了一种新的黑箱并行处理方法。新方法基于多色排序的概念和求解器中的自动重排序过程。在三维有限边缘元涡流分析的背景下，对并行性能进行了评估。该方法在CG迭代次数略有增加的情况下获得了较高的并行度，并获得了较高的并行性能。
Proposes a new black-box-type parallel processing method for the incomplete Cholesky conjugate gradient (ICCG) solver. The new method is based on a multicolor ordering concept and an automatic reordering process in the solver. Parallel performance is evaluated in the context of three-dimensional finite edge-element eddy-current analysis. The proposed method attains high parallelism with a small increase in CG iterations and achieves high parallel performance.
