本文提出的组合紧致差分（CCD）格式具有计算量小、精度高的特点，适合于大规模高精度计算。本文在Mattor等人提出的三对角矩阵问题的基础上，发展了块三对角阵CCD格式的并行化，适用于区域分解技术。对该算法的并行效率进行了测试。结果表明，CCD方案的并行化是非常有效的。
The combined compact difference (CCD) scheme proposed by the authors has high accuracy with comparatively low computational cost and it is promising for large scale computation with high accuracy. The parallelization of CCD schemes with a block tridiagonal matrix is developed, which is based on that of the tridiagonal matrix problem proposed by Mattor et al., and is suitable for the domain decomposition technique. The parallel efficiency of this algorithm is measured. The results show that the parallelization of CCD schemes is highly effective.
