Speedy: An Integrated Performance Extrapolation Tool for pC++ Programs

. Performance Extrapolation is the process of evaluating the performance of a parallel program in a target execution environment using performance information obtained for the same program in a different execution environment. Performance extrapolation techniques are suited for rapid performance tuning of parallel programs, particularly when the target environment is unavailable. This paper describes one such technique that was developed for data-parallel C++ programs written in the pC++ language. In pC++, the programmer can distribute a collection of objects to various processors and can have methods invoked on those objects execute in parallel. Using performance extrapolation in the development of pC++ applications allows tuning decisions to be made in advance of detailed execution performance measurements. The current pC++ language system includes t, an integrated environment for analyzing and tuning the performance of pC++ programs. This paper presents speedy, a new addition to ..
