OSTI ID:5595190
Variants of the numerical Schwarz algorithms for solving elliptic partial differential equations on multiprocessing systems are described and analyzed. The methods are described in terms of domain decomposition techniques and mathematically cast into an inter/outer matrix iteration form. It is shown that under certain matrix nonnegativity conditions that the convergence rate of the global iteration is invariant to the amount of overlap of the subdomains when one inner iteration is taken.
