Description
Summary: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.
