Silent data corruption SDC poses a great challenge for high-performance computing HPC applications as we move to extreme-scale systems. [] Key Method In this work, we propose partial replication to overcome this limitation. More specifically, we have observed that not all processes of an MPI application experience the same level of data variability at exactly the same time. Thus, we can smartly choose and replicate only those processes for which our lightweight data-analytic detectors would perform poorly…

Toward General Software Level Silent Data Corruption Detection for Parallel Applications
TLDR
This work proposes partial replication to overcome the limitation that not all processes of an MPI application experience the same level of data variability at exactly the same time, and proposes a new evaluation method based on the probability that a corruption will pass unnoticed by a particular detector.
Efficient detection of silent data corruption in HPC applications with synchronization-free message verification
TLDR
This paper proposes the first solution of SDC detection without requiring synchronization and additional message transmission between replicas, which combines message logging with an innovative asynchronous message comparison mechanism, which uses specialized service routines to perform progress comparison without interfering target program execution.
Evaluating the Viability of Using Compression to Mitigate Silent Corruption of Read-Mostly Application Data
TLDR
This paper proposes an application-independent mechanism to efficiently detect and correct silent data corruption (SDC) in read-mostly memory, where SDC may be most likely to occur, and uses memory protection mechanisms to maintain compressed backups of application memory.
Hardening Strategies for HPC Applications
TLDR
This work presents and discusses radiation experiments that cover a total of more than 352,000 years of natural exposure and fault-injection analysis, and proposes and analyzes the impact of selective hardening for HPC algorithms.
Experimental and analytical study of Xeon Phi reliability
TLDR
An in-depth analysis of transient faults effects on HPC applications in Intel Xeon Phi processors based on radiation experiments and high-level fault injection is presented and it is shown that portions of applications can be graded by different criticalities.
Scaling and Resilience in Numerical Algorithms for Exascale Computing
TLDR
A new adaptive scheduler is proposed that optimize the parallel efficiency by minimizing the time-subdomain length without making communication of time- subdomains too costly, and it is demonstrated that it is possible to obtain time-parallel speedup on the nonlinear shallow water equation, beyond what is possible using conventional spatial domain-decomposition techniques alone.
Radiation-Induced Error Criticality in Modern HPC Parallel Accelerators
TLDR
It is shown that arithmetic operations are less critical for the K40, while Xeon Phi is more reliable when executing particles interactions solved through Finite Difference Methods, and iterative stencil operations seem the most reliable on both architectures.
User-level failure detection and auto-recovery of parallel programs in HPC systems
TLDR
This paper proposes an innovative method for the unprivileged user to achieve failure detection of job execution and automatic resubmission of failed jobs, and implements the proposed method as a tool named automatic re-launcher (ARL) and evaluates it on the Tianhe-2 system.
Detection of Silent Data Corruptions in Smoothed Particle Hydrodynamics Simulations
TLDR
Selective particle replication (SPR) is proposed herein as the first particle-based replication method for detecting SDCs in Smoothed particle hydrodynamics (SPH) simulations, a mesh-free Lagrangian method commonly used to perform hydrodynamic simulations in astrophysics and computational fluid dynamics.
Resiliency in numerical algorithm design for extreme scale simulations
TLDR
A broad range of perspectives are gathered on the role of algorithms, applications and systems in achieving resilience for extreme scale simulations to discuss novel ways to make applications resilient against detected and undetected faults.

TLDR
This paper studies the potential for redundancy to detect and correct soft errors in MPI message-passing applications while investigating the challenges inherent to detecting soft errors within MPI applications by providing transparent MPI redundancy.
Processor-Level Selective Replication
TLDR
A processor-level technique called selective replication, by which the application can choose where in its application stream and to what degree it requires replication, is proposed, which shows that with about 59% less overhead than full duplication, selective replication detects 97% of the data errors and 87%" of the instruction errors that were covered by full duplication.
