Felix Zhengbuo Guan: Evaluation of a mixed-precision finite volume limiter for the ADER-DG algorithm
SCCS Colloquium |
This presentation evaluates a mixed-precision implementation of a finite volume limiter for the ADER-DG Algorithm. The implementation extends the Python API of the ExaHyPE engine, which is built on top of the Peano framework. It allows for specifying the numerical precision of the individual kernels of the ADER solver and Finite Volume Limiter, and is then used to study the resulting error margin when using mixed precision. In particular, we assess how sensitive the kernels of the finite volume limiter are to the use of double, single, and half precision. The question addressed is, in which settings mixed precision is viable, considering its potential error margin.
