Abstract:

Feedback information has proven useful in guiding optimizations in compilers and post-link optimizers. Program performance behavior can change over time and may invalidate the feedback information. Low overhead monitoring can be used to detect such changes, using performance metrics such as CPI. On a loaded SMT system, where other threads...More
