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…

Fine spectral analysis of preconditioned matrices and matrix-sequences arising from stage-parallel implicit Runge-Kutta methods of arbitrarily high order
Ivo Dravins, Stefano Serra-Capizzano, Maya Neytcheva
The use of high order fully implicit Runge-Kutta methods is of significant importance in the context of the numerical solution of transient partial differential equations, in parti…
