Description
In this talk, I will present the latest developments of ongoing efforts at LSU to speed up simulations in the Einstein Toolkit under CarpetX. In particular, I will present our new results using Multi-Step Runge-Kutta time integrators which can speed up BBH evolutions by 30% with simple algorithmic changes. In order to do that, I will carefully review the stability theory of ODE solvers, which should be particularly relevant to new students of Numerical Relativity. I will also present exciting new developments in CapyrX, CarpetX multipatch infrastructure.
