Logs are semi-structured text generated by logging statements in software source code. In
recent decades, software logs have become imperative in the reliability assurance …

The next generation of supercomputers will break the exascale barrier. Soon we will have
systems capable of at least one quintillion (billion billion) floating-point operations per …

We conducted a cloud outage study (COS) of 32 popular Internet services. We analyzed
1247 headline news and public post-mortem reports that detail 597 unplanned outages that …

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 …

Hardware failures have a big impact on the dependability of large-scale data centers. We
present studies on over 290,000 hardware failure reports collected over the past four years …

Increase in graphics hardware performance and improvements in programmability has
enabled GPUs to evolve from a graphics-specific accelerator to a general-purpose …

We present a comprehensive study of 136 system failures attributed to network-partitioning
faults from 25 widely used distributed systems. We found that the majority of the failures led …

In this paper, we analyze a workload trace from the Google cloud cluster and characterize
the observed failures. The goal of our work is to improve the understanding of failures in …

In today's commercial data centers, the computation density grows continuously as the
number of hardware components and workloads in units of virtual machines increase. The …

Continuing increase in the computational power of supercomputers has enabled large-scale
scientific applications in the areas of astrophysics, fusion, climate and combustion to run …
