摘要
We consider the parallelization of numerical methods for the solution of block-tridiagonal linear systems. A general partitioning approach is discussed that allows to distribute the system in different ways on p processors using a divide and conquer approach based on low rank modifications. An analysis of the numerical properties and the preservation of structure during the method is given and some known special cases of this method are discussed.
