Detailed modeling of the performance of large applications is difficult. Applications can take a very long time to run on real hardware and it is impractical to simulate them to completion on modern, detailed performance models. Furthermore, some applications have complex execution environments that cannot easily be reproduced on a simulator, so properly setting up the applications to run on a variety of simulators can be difficult. The PinPoints methodology addresses these problems using the well-known SimPoint tool to determine representative portions of an application to simulate, and Pin to avoid tedious and error-prone application setup altogether. The resulting representative simulation regions, called PinPoints, can then be used for simulation and performance projection instead of simulating the entire application. This results in a drastic reduction in simulation time. Further, by using the Pin-based program-capture and deterministic replay framework called PinPlay we guarantee repeatability of PinPoints for single and multi-threaded programs.
- See SPEC page high-lighting PinPoints research.
- SPEC2006 PinPoints pinballs available from UGhent.
- PinPoints methodology works with Intel® Software Development Emulator (Intel SDE) now (since version 7.45). Please download the SDE/PinPlay scripts package and extract it at the root of an SDE kit (version 7.45 or higher). This has only been tested with Linux SDE kit.
PinPoints tools/scripts are distributed with the PinPlay kit (Linux only). See one of the tutorials below for more details.
