Fault-Tolerance for HPC: Theory and Practice

SESSION: Fault-Tolerance for HPC: Theory and Practice

EVENT TYPE: Tutorials

TIME: 8:30AM - 5:00PM

ROOM:388

ABSTRACT:

Resilience is a critical issue for large-scale platforms. This tutorial
provides a comprehensive survey of fault-tolerant techniques for
high-performance computing, with a fair balance between practice and theory.
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) General-purpose techniques, which include several checkpoint and
rollback recovery protocols, replication, prediction and silent error
detection;
(iii) Application-specific techniques, such as ABFT for grid-based algorithms
or fixed-point convergence for iterative applications; and
(iv) Practical deployment of fault tolerant techniques with User Level Fault
Mitigation (a proposed MPI extension to the MPI forum). Relevant examples
based on widespread computational solver routines will be protected with a mix
of checkpoint-restart and advanced recovery techniques in a hands-on session.

The tutorial is open to all SC'14 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. However, basic knowledge of MPI
will be helpful for the hands-on session.
