A GPU-accelerated mixed-precision WENO method for extremal black hole and gravitational wave physics computations
Scott E. Field, Sigal Gottlieb, Zachary J. Grant +2
We develop and use a novel mixed-precision weighted essentially non-oscillatory (WENO) method for solving the Teukolsky equation, which arises when modeling perturbations of Kerr b…
Strong Stability Preserving Integrating Factor Two-step Runge--Kutta Methods
Leah Isherwood, Zachary J. Grant, Sigal Gottlieb
Problems that feature significantly different time scales, where the stiff time-step restriction comes from a linear component, implicit-explicit (IMEX) methods alleviate this rest…
Downwinding for Preserving Strong Stability in Explicit Integrating Factor Runge--Kutta Methods
Leah Isherwood, Zachary J. Grant, Sigal Gottlieb
Strong stability preserving (SSP) Runge-Kutta methods are desirable when evolving in time problems that have discontinuities or sharp gradients and require nonlinear non-inner-prod…
Strong Stability Preserving Integrating Factor Runge-Kutta Methods
Sigal Gottlieb, Zachary J. Grant, Leah Isherwood
Strong stability preserving (SSP) Runge-Kutta methods are often desired when evolving in time problems that have two components that have very different time scales. Where the SSP…
