Abstract
The partition method of Wang, for the solution of tridiagonal linear systems, is analysed with regard to data transport between the processors of a parallel (local memory) computer. We propose a modification which reduces the amount of data transport considerably, without affecting the computational complexity and which has about the same degree of parallelism as the original version. We will also discuss the effects of this modification to a generalized version for banded systems. The parallel solution of a bidiagonal system is considered.
