Performance evaluation of mixed-precision Runge-Kutta methods for the solution of partial differential equations
Ivo Dravins, Marcel Koch, Victoria Griehl +1
This work focuses on the numerical study of a recently published class of Runge-Kutta methods designed for mixed-precision arithmetic. We employ the methods in solving partial diff…
