摘要

One of the most challenging issues in the case of many and multi-core architectures is how to exploit their potential computing power in legacy systems without a deep knowledge of their architecture. The analysis of static dependence and dynamic data dependences of a program run, can help to identify independent paths that could have been computed by individual parallel threads. The statistics of reusing the data and its size is also crucial in adapting the application in GPU many-core hardware architecture because of specific memory hierarchies. The proposed profiling system accomplishes static data analysis and computes dynamic dependencies for Java programs as well as recommends parts of source code with the highest potential for parallelization in GPU. Such an analysis can also provide starting point for automatic parallelization.
