Performance comparison of some patch solvers 
The benchmark is carried out for the 
Explosion in a Box testcase.
-  Unigrid resolution of 256^3 cells 
-  Calculation with CFL-No. 0.9 to time t=0.25
-  Load balancing with space filling curve
-  All test on shc.cacr
-  Grind time: wall clock time required to advance the solution per cell and time step
