Extracting Rich Performance Analysis from Simple Time Measurements

摘要

Embodiments of the invention rely on simple time measurements to extract rich performance analysis from a graphics program. The invention times the program as it repeatedly executes on a selected platform, while a series of variations are applied to the program with each execution. As a result, without requiring any specific profiling tools for the platform, a developer can analyze and understand the performance characteristics of the program based upon these elapsed time measurements. The program can then be optimized to incorporate variations that improve execution time.
