	~~Below are~~ the questions ~~addressed in the Resilience Research Panel. Please add your comments (with you name) after each question.~~		The main question is where does resilience fit into the X-stack runtime abstract architecture, with guiding questions being:

	1) What features of other levels of the stack (algorithm, programming model, compiler, runtime, and hardware) should resilience depend on?		1) What features of other levels of the stack (algorithm, programming model, compiler, runtime, and hardware) should resilience depend on?
