Abstract The Young/Daly formula provides an approximation of the optimal checkpointing
period for a parallel application executing on a supercomputing platform. It was originally …

Resilience is one of the key challenges in maintaining high efficiency of future extreme scale
supercomputers. Researchers and system practitioners rely on field-data studies to …

HPC workload analysis and resource consumption characteristics are the key to driving
better operation practices, system procurement decisions, and designing effective resource …

Predicting which node will fail and how soon remains a challenge for HPC resilience, yet
may pave the way to exploiting proactive remedies before jobs fail. Not only for increasing …

The Cray XK7 Titan was the top supercomputer system in the world for a long time and
remained critically important throughout its nearly seven year life. It was an interesting …

As we approach exascale computing, large-scale HPC systems are becoming increasingly
power-constrained, requiring them to run HPC workloads in an energy-efficient manner. The …

With the scaling up of high-performance computing systems in recent years, their reliability
has been descending continuously. Therefore, system resilience has been regarded as one …

Checkpoint and restart mechanisms have been widely used in large scientific simulation
applications to make forward progress in case of failures. However, none of the prior works …

This paper revisits the failure 1 temporal independence hypothesis which is omnipresent in
the analysis of resilience methods for HPC. We explain why a previous approach is …

The dramatic increase in the scale of current and planned high-end HPC systems is leading
new challenges, such as the growing costs of data movement and IO, and the reduced mean …
