Abstract

Performance analysis and tuning of parallel/distributed applications are very difficult tasks for non-expert programmers. It is necessary to provide tools that automatically carry out these tasks. Many applications have a different behavior according to the input data set or even change their behavior dynamically during the execution. Therefore, it is necessary that the performance tuning can be done on the fly by modifying the application according to the particular conditions of the execution. A dynamic automatic performance tuning environment supported by dynamic instrumentation techniques is presented. The environment is completed by a pattern based application design tool that allows the user to concentrate on the design phase and facilitates on the fly overcoming of performance bottlenecks.
