Abstract : This thesis work is done in the general context of the ERC funded Defying Amdahl's Law (DAL) project which aims at exploring the micro-architectural techniques that will enable high performance on future many-core processors. The project envisions that despite future huge investments in the development of parallel applications and porting it to the parallel architectures, most applications will still exhibit a significant amount of sequential code sections and, hence, we should still focus on improving the performance of the serial sections of the application. In this thesis, the research work primarily focuses on studying the difference between parallel and serial sections of the existing multi-threaded (MT) programs and exploring the design space with respect to the processor core requirement for the serial and parallel sections in future many-core with area-performance tradeoff as a primary goal.
