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. Based upon 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. tritisicWebceptible to radiation-induced soft errors, which can lead to silent data corruption or system instability.
