''Containment domains'' are a programming construct with weak transactional semantics specifically designed to enable applications
to express resiliency concerns. The goal of containment domains is to enable resilient-by-default applications that can
be progressively and systematically optimized and tuned to improve their performance and
efficiency. The key to containment domains is abandoning the prevailing
one-size-fits all approach to resiliency and embrace the diversity of application needs
and resiliency mechanisms. The new capabilities include
tuning and specializing error detection, state preservation and restoration, and
recovery schemes. Containment domains are nested to take advantage of the machine
hierarchy and to enable effective low-complexity uncoordinated localized recovery. They
also provide the means of expressing algorithm-specific detection and recovery. These
characteristics are critical to achieve the power- and resource-efficiency needed for
extreme-scale computing while guaranteeing correct results.  The programming model is
accompanied by an execution model that provides interfaces to runtime services. The
containment domains runtime consolidates various resiliency techniques and optimizations
and provides the interfaces for co-tuning application and system level resiliency. The
combination of programming and execution model is used to implement a default resiliency
scheme which is then amenable to progressive and aggressive optimization.
