Many modern applications have a significant operating system (OS) component. The OS execution affects various architectural states, including the dynamic branch predictions, which are widely used in today's high-performance microprocessor designs to improve performance. This impact tends to become more significant as the designs become more deeply pipelined and more speculative. In this paper, we...
Paging policies implemented by today's operating systems cause scientific applications to exhibit poor performance, when the application's working set does not fit in main memory. This has been typically attributed to the sub-optimal performance of LRU-like virtual-memory replacement algorithms. On one end of the spectrum, researchers in the past have proposed fully automated compiler-based techniques...
