These are timing and accuracy results to solve the system $$ \gathered -\nabla\cdot(a\nabla u)+b\cdot\nabla u+cu=f\quad\text{on }\Omega, \\ a\frac{\partial u}{\partial n}+\gamma u=g\quad\text{on }\partial Omega. \endgathered $$ with $b=0$ with $\Omega=[0,1]^2$ and a regular grid of size $129 \times 129$ with one set of diagonals and linear finite elements. Multigrid was used, with m1 presmoothing steps, m2 postsmoothing steps, and p coarse-correction steps in each MG-step, and r iterations of MG-step at each refinement level. Richardson, Jacobi, or Gauss-Seidel smoothing was used. At the coarsest level, only the smoothers were employed, i.e., no special solver was used at the coarsest level. The four columns of numbers are L2 error, H1 error, User ms, and GC ms. The L2 and H1 errors were estimated by injecting the approximate solution into a $257 \times 257$ grid and comparing it with the interpolant of the true solution on the fine grid. The problems are roughly in increasing order of difficulty; in the last problem, for example, the stiffness coefficient $a$ varies from 1.0 to 21.0 over the domain. User ms is the amount of user+system time to solve the linear system only; every once in a while there was a garbage collection during the solution process, whose time is measured separately. The tests were run on a box: % cat /proc/cpu model name : Intel(R) Core(TM)2 Quad CPU Q8200 @ 2.33GHz % uname -a Linux heine 3.0.0-17-generic #30-Ubuntu SMP Thu Mar 8 20:45:39 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux % gsi -v v4.6.4 20120222164157 x86_64-unknown-linux-gnu "./configure 'CC=gcc -march=native -fschedule-insns -frename-registers' '--enable-single-host' '--enable-shared' '--enable-multiple-versions'" % gcc -v Using built-in specs.
