Reliability, availability, and serviceability (RAS) events are recorded from almost all components in a high-performance computing (HPC) system and therefore provide useful insights into the…
Reliability, availability and serviceability (RAS) logs of HPC resources, when closely investigated in spatial and temporal dimensions, can provide invaluable information regarding system status,…
High performance computing (HPC) applications are affected by multiple types of errors occurring in HPC systems which hinder with their ability to make forward progress and their correctness. The…
Today's High Performance Computing (HPC) systems are able to deliver performance in order of Petaflops due to fast computing devices, interconnect, and back-end storage systems. HPC systems contain…
In this work, we discover that workload characteristics, certain GPGPU cards, temperature and power consumption could have predictive or associative capabilities with GPGPU errors, but it is non-…
Analyses of large-scale HPC systems has demonstrated the need to implement process failure resilience in long-running applications, which are susceptible to multiple failures during their execution.…
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 understand…
