Strong Scaling of HPX and MPI AMR

We compared an application which is using a 3-D adaptive mesh refinement (AMR) algorithm to solve the semi-linear wave equation with exponent p = 7 with second order finite differencing in space and Runge-Kutta third order integration in time. We implemented this application using conventional techniques based on MPI and using HPX. The figures below show a comparison of the strong scaling behavior of both applications. Continue reading
