Runtime Support for Maximizing Performance on Multicore Systems: Maximizing Performance on Multicores Kishore Kumar Pusukuri

Since multicore systems offer greater performance via parallelism, future computing is progressing towards use of machines with large number of cores. However, due to the complex interaction among characteristics of multithreaded applications, operating system policies, and architectural characteristics of multicore systems, delivering high performance on multicore systems is a challenging task. This work addresses the above challenge by developing runtime techniques to achieve high performance when running a single multithreaded application as well as high system utilization and fairness when running multiple multithreaded applications. The runtime techniques are based on a simple monitoring system that captures important application characteristics and relevant architectural factors with negligible overhead.
