Abstract:
Soft error rates are increasing as modern architec- tures require increasingly small features at low voltages. Due to the large number of components used in HPC architectures, these are particularly vulnerable to soft errors. Hence, when designing applications that run for long time periods on large machines, algorithmic resilience must be taken into account. In this paper we analyse the inherent resiliency of a-posteriori limiting procedures in the context of the explicit ADER DG hyperb...     »
