Ankara : The Department of Computer Engineering and the Graduate School of Engineering and Science of Bilkent University, 2013.Thesis (Master's) -- Bilkent University, 2013.Includes bibliographical references leaves 76-81.The full potential of chip multiprocessors remains unexploited due to architecture
oblivious thread schedulers used in operating systems, and thread-oblivious
memory access schedulers used in off-chip main memory controllers. For the
thread scheduling, we introduce an adaptive cache-hierarchy-aware scheduler that
tries to schedule threads in a way that inter-thread contention is minimized. A
novel multi-metric scoring scheme is used that specifies the L1 cache access characteristics
of a thread. The scheduling decisions are made based on multi-metric
scores of threads. For the memory access scheduling, we introduce an adaptive
compute-phase prediction and thread prioritization scheme that efficiently categorize
threads based on execution characteristics and provides fine-grained prioritization
that allows to differentiate threads and prioritize their memory access
requests accordingly.Aktürk, İsmailM.S
