Search for: [Abstract = "In addition to these algorithmic improvements, we also try to minimise the communication overhead withinthe communication model currently used by the GridSolve middleware. We present numerical experiments on 3D bubblyflow problems using heterogeneous computing hardware that show lower computing times and better speed\-up for theChronopoulos\/Gear variant of conjugate gradients. Finally, we suggest extensions to both the iterative algorithm and themiddleware for improving granularity."]
