The enormous and growing complexity of today\'s high-end systems has
increased the already significant challenges of obtaining high performance on today\'s equally complex scientific applications. Application scientists are faced with a daunting challenge in tuning their codes to exploit performance-enhancing architectural features. The Performance Engineering Research Institute (PERI) is working towards the goal of automating portions of the performance tuning process. This paper describes PERI’s overall strategy for auto-tuning tools, and recent progress in both building auto-tuning tools and demonstrating
their success on kernels, some taken from large-scale applications.
