iDynamic Optimization Infrastructure and Algorithms for IA-64,j Master of Science thesis

Dynamic Optimization refers to any program optimization performed after the initial static compile time. While typically not designed as a replacement for static optimization, dynamic optimization is a complementary optimization opportunity that leverages a vast amount of information that is not available until runtime. Dynamic optimization opens the doors for machine and user-specific optimizations without the need for original source code. This thesis includes three contributions to the field of dynamic optimization. The first main goal is the survey of several current approaches to dynamic optimization, as well as its related topics of dynamic compilation, the postponement of some or all of compilation until runtime, and dynamic translation, the translation of an executable from one instruction-set architecture (ISA) to another. The second major goal of this thesis is the proposal of a new infrastructure for dynamic optimization in EPIC architectures. Several salient features of the EPIC ISA prove it to be not only a good candidate for dynamic optimization, but such optimizations are essential for scalability that is up to par with superscalar processors.
