Query: Rolex: Resilience-Oriented Language Extensions for Extreme-Scale Systems   Future exascale high-performance computing (HPC) systems will be constructed
from VLSI devices that will be less reliable than those used today, and faults
will become the norm, not the exception. This will pose significant problems
for system designers and programmers, who for half-a-century have enjoyed an
execution model that assumed correct behavior by the underlying computing
system. The mean time to failure (MTTF) of the system scales inversely to the
number of components in the system and therefore faults and resultant system
level failures will increase, as systems scale in terms of the number of
processor cores and memory modules used. However every error detected need not
cause catastrophic failure. Many HPC applications are inherently fault
resilient. Yet it is the application programmers who have this knowledge but
lack mechanisms to convey it to the system.
  In this paper, we present new Resilience Oriented Language Extensions (Rolex)
which facilitate the incorporation of fault resilience as an intrinsic property
of the application code. We describe the syntax and semantics of the language
extensions as well as the implementation of the supporting compiler
infrastructure and runtime system. Our experiments show that an approach that
leverages the programmer's insight to reason about the context and significance
of faults to the application outcome significantly improves the probability
that an application runs to a successful conclusion.
