Towards Self­Tuning Software

Modern processors contain a wealth of sophisticated performance counters that can be used to understand how the machine is performing in real time. In collaboration with Intel, we are building systems that use performance counter information to optimize code on the machine as it runs, without any programmer intervention. We envision a platform that allows programs to adapt to their hardware environment for optimal performance. We are actively investigating systems that can automatically repair false sharing, and that can reduce off­chip cache misses.
