Summary or Abstract : Microprocessor design is currently in the midst of a sea change, which will have a significant impact on all computer applications including database management systems, the focus of this thesis. For the past several decades, microprocessor performance has been driven primarily by higher clock rates and the subsequent faster execution of a single stream of instructions (a single thread). Faster chip speeds require more power and produce more heat. A single thread also has difficulty providing enough work to keep a chip busy because applications often have to wait for high-latency operations such as loading data from memory, an operation that becomes more expensive in terms of processor cycles the faster a chip is. For these reasons, processor architects have recently begun to improve processor performance by increasing the degree of on-chip thread-level parallelism rather than the chip speed. The processor designs featuring on-chip parallelism are termed chip multiprocessors and include multi-core and simultaneous multithreading processors, both of which are examined in this thesis..
