2008-11: Reliability, Availability, and Serviceability (RAS) for Petascale High-End Computing and Beyond

June 16th, 2015

This project aims at scalable technologies for providing high-level RAS for next-generation petascale scientific high-end computing (HEC) resources and beyond as outlined by the U.S. Department of Energy (DOE) Forum to Address Scalable Technology for Runtime and Operating Systems (FAST-OS) and the U.S. National Coordination Office for Networking and Information Technology Research and Development (NCO/NITRD) High-End Computing Revitalization Task Force (HECRTF) activities. Based on virtualized adaptation, reconfiguration, and preemptive measures, the ultimate goal is to provide for non-stop scientific computing on a 24×7 basis without interruption. The taken technical approach leverages system-level virtualization technology to enable transparent proactive and reactive fault tolerance mechanisms on extreme scale HEC systems. This effort targets: (1) reliability analysis for identifying pre-fault indicators, predicting failures, and modeling and monitoring component and system reliability, (2) proactive fault tolerance technology based on preemptive migration away from components that are about to fail, (3) reactive fault tolerance enhancements, such as checkpoint interval and placement adaption to actual and predicted system health threats, and (4) holistic fault tolerance through combination of adaptive proactive and reactive fault tolerance.
