Convergence of parallel multisplitting USAOR methods for block H-matrices linear systems

摘要

In this paper, We present parallel multisplitting blockwise relaxation methods for solving the large sparse blocked linear systems, which come from the discretizations of many discrential equations, and study the convergence of our methods associated with USAOR multisplitting when the coefficient matrices of the blocked linear systems are block H-matrices. A lot of numerical experiments show that our methods are applicable and efficient.
