DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: Resilience becomes 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:=0A=0A(i) An overview of failure types (software/hardware, transient/fail-stop), and typical probability distributions (Exponential, Weibull, Log-Normal);=0A=0A(ii) General-purpose techniques, which include several checkpoint and rollback recovery protocols, replication, prediction and silent error detection;=0A=0A(iii) Application-specific techniques, such as ABFT for grid-based algorithms or fixed-point convergence for iterative applications, user-level checkpointing in memory; and=0A=0A(iv) Practical deployment of fault tolerant techniques with User Level Fault Mitigation (a proposed MPI standard extension). Relevant examples based on ubiquitous computational solver routines will be protected with a mix of checkpoint-restart and advanced recovery techniques in a hands-on session.=0A=0AThe tutorial is open to all SC'15 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.
