Panel Ocp Hw Operation At Scale Reliability To Address Silent Data Corruptions

Silent Data Corruptions At Scale

Silent Data Corruptions At Scale These are just a few examples of how dcdiag searches for silent data errors, but there are other mechanisms that can be used. additional tests check core to core and socket to socket communications, caches, and other non compute functions of the processor. " as infrastructure rapidly shifts towards ai, the need for coordinated efforts to combat silent data corruptions at scale only grows. we need to treat hardware resilience as a first order concern and ocp has been instrumental in bringing together a collaborative ecosystem.

Mitigating Silent Data Corruptions In HPC Applications Across Multiple Program Inputs? | Argonne ... We provide a high level overview of the mitigations to reduce the risk of silent data corruptions within a large production fleet. in our large scale infrastructure, we have run a vast library of silent error test scenarios across hundreds of thousands of machines in our fleet. Hyperscalers are reporting frequent silent data corruptions (sdcs)—a.k.a. silent errors or corrupt execution errors (cees)—in their cloud fleets caused by silicon manufacturing defects. notably, sdcs at scale exhibit error occurrence rates on the order of one fault within a thousand devices. Based on this experience, we determine that reducing silent data corruption requires not only hardware resiliency and production detection mechanisms, but also robust fault tolerant software architectures. Through this workstream, we’ll develop consistent metrics about silent data errors and corruptions for the broader industry to track. we’ll also contribute test execution frameworks and.

We are sharing how we detect and remediate silent data corruption on a scale of hundreds of thousands of machines with a real world example. Undetected defects “silent data corruption due to silicon latent defects and aging. (1,000 dppm!)” “frequent unexplained hw failures with “no issue found” at high rates” “rare, short term computational errors on systems that passed all manufacturing tests successfully”. In this paper, we describe testing strategies to detect silent data corruptions within a large scale infrastructure. given the challenging nature of the problem, we experimented with diferent methods for detection and mitigation. We provide a high level overview of the mitigations to reduce the risk of silent data corruptions within a large production fleet. in our large scale infrastructure, we have run a vast library of silent error test scenarios across hundreds of thousands of machines in our fleet.
