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 …

Smaller transistor sizes and reduction in voltage levels in modern microprocessors induce
higher soft error rates. This trend makes reliability a primary design constraint for computer …

Reliability is a serious concern for future extreme-scale high-performance computing (HPC)
systems. While the HPC community has developed various resilience solutions, the solution …

Rapid progress in the CMOS technology for the past 25 years has increased the
vulnerability of processors towards faults. Subsequently, focus of computer architects shifted …

Redundant multithreading (RMT) is an effective reliability solution that provides thread-level
replication; however, it imposes additional overheads in terms of performance loss or energy …

In the presence of accelerated fault rates, which are projected to be the norm on future
exascale systems, it will become increasingly difficult for high-performance computing (HPC) …

In this document, we develop a structured approach to the management of HPC resilience
based on the concept of resilience-based design patterns. A design pattern is a general …

As processors continue to boost the system performance with higher circuit density,
shrinking process technology and near-threshold voltage (NTV) operations, they are …

Due to the system scaling, transient errors caused by external noise, eg, heat fluxes and
particle strikes, have become a growing concern for the current and upcoming exa-scale …

Recent reliability issues with one of the fastest supercomputers in the world, Titan at Oak
Ridge National Laboratory (ORNL), demonstrated the need for resilience in large-scale …
