A New Parallel Method for Binary Black Hole Simulations

Figure 2

An example to show the difference between SPM and MPM. The red line is control flow and blue line is communication flow. The green blocks are the calculation steps with Runge-Kutta (RK) method and the yellow cycles are the communication operations between neighbor mesh levels.

(a) SPM executes different mesh levels one by one

(b) MPM executes different mesh levels in parallel
