High resolution performance results

24 processors, SHC

  • For the following tests we used the computational domain: x = [-0.01,0.1], y = [0, 0.025]
  • Clawpack: base level 220x50 cells with levels refined 2,2,4,4 times respectively, max cfl = 0.9
  • WENO-TCD: base level 220x50 cells with levels refined 2,2,2,4 times respectively, max cfl = 0.85

64 processors, SHC

  • For the following tests we used the computational domain: x = [-0.01,0.1], y = [0, 0.025]
  • 5 levels: base level 110x25 cells with 4 more levels refined 2,2,4,4 times respectively
  • The "normalized cost/timestep" is adjusted for the differing base grid resolutions
