Performance Evaluation of Stabilized Corrections for Mixed Precision Runge--Kutta Methods

César Herrera, John Driscoll, Sigal Gottlieb +3

Mixed precision Runge--Kutta methods reduce the cost of the expensive implicit solves in diagonally implicit Runge--Kutta (DIRK) schemes by evaluating them in low precision, while…
