WebThe silent data corruption (SDC) problem is attracting more and more attentions because it is expected to have a great impact on exascale HPC applications. SDC faults are hazardous in that they pass unnoticed by hardware and can lead to wrong computation results. In this work, we formulate SDC detection as a runtime one-step-ahead prediction … Webgenerated message does not indicate what data are corrupted; 3) silent data corruption which means the data corruption is not detected; and 4) misreported data corruption which means one or more blocks are reported as corrupted while actually these blocks are intact and uncorrupted. Data corruption causes: For data corruption causes, we use
WebAbstract—While hyper-scale data centers are reporting a growing number of Silent Data Errors (SDEs), existing tech-niques alone are still insufficient to build an SDE-resilient system. In this work, we propose the adoption of Coded Computation to mitigate SDE computation errors efficiently.

Written by Campbell Kwan, Contributor on March 17, … WebOct 1, 2016 · Silent data corruptions (SDCs), or silent errors, are one of the major sources that corrupt the execution results of HPC applications without being detected. Here in this paper, we explore a set of novel SDC detectors – by leveraging epsilon-insensitive support vector machine regression – to detect SDCs that occur in HPC applications.
