We derive a multilevel algorithm to solve variable coefficient elliptic boundary value problems on adaptively refined structured meshes, and we design a cache optimized version of this algorithm.The operations are optimized to exploit the cache memory subsystem. We present numerical results demonstrating the efficiency of the cache optimization. Copyright © 2004 John Wiley & Sons, Ltd.
