FEniCS project at large scales
Solving Poisson on a Unit Cube is a fairly basic test, but even that gets challenging at large scale. Here are some results with 24576 cores on  ARCHER (12.5 billion dofs). Algebraic Multigrid is the way to go, and PETSc has two 64-bit interfaces, GAMG and HYPRE. GAMG converges in fewer iterations, but the setup time (not shown) is more, so in fact, there is little difference between them.
