Abstract
As the push for extreme scale performance continues to make computer architectures increasingly complex, there has been a call for better programming models, and the systems to support them. Todays microprocessors now expose more system resources than ever to software, leaving it up to the application programmer to manage them. Studies have shown that the energy efficiency of future technologies may eventually affect the ultimate performance of multicore processors, and so programmers are forced to optimize systems for both performance and energy in the midst of countless configurable parameters - an extremely difficult task. Self-aware systems can configure themselves through introspection, providing performance and energy optimization without pressing an unrealistic burden on the programmer. However, to build effective self-aware systems, we must identify useful sources of adaptivity. This thesis will show the effectiveness of a number of adaptive mechanisms for self-aware multicore systems. We show that adding these mechanisms improves efficiency, and then make a case for coordinated adaptive systems. Coordinated systems treat adaptivity as a first-class object, and can outperform all non-adaptive, statically configured, and uncoordinated adaptive systems that do not possess a general view of system-wide adaptivity.
