An Overview of Fault-Tolerant Techniques for HPC
SESSION: An Overview of Fault-Tolerant Techniques for HPC
EVENT TYPE: Tutorials
TIME: 1:30PM - 5:00PM
Presenter(s):Thomas Herault, Yves Robert
ROOM:301
ABSTRACT:
Resilience is a critical issue for large-scale platforms. This tutorial provides a comprehensive survey on fault-tolerant techniques for high-performance computing. It is organized along four main topics: (i) An overview of failure types (software/hardware, transient/fail-stop), and typical probability distributions
(Exponential, Weibull, Log-Normal); (ii) Application-specific techniques, such as
ABFT for grid-based algorithms or fixed-point convergence for iterative applications; (iii) General-purpose techniques, which include several checkpoint and rollback recovery protocols, possibly combined with replication; and (iv) Relevant execution scenarios will be evaluated and compared through quantitative models (from Young's approximation to Daly's formulas and recent work).
The tutorial is open to all SC13 attendees who are interested in the current status and expected promise of fault-tolerant approaches for scientific applications. There are no audience prerequisites; background will be provided for all protocols and probabilistic models. Only the last part of the tutorial devoted to assessing the future of the methods will involve more advanced analysis tools.
