As multi-core processors are deployed in mainstream computing, the need for software tools to help parallelize programs is increasing dramatically. Data-dependence profiling is an important program analysis technique to exploit parallelism in serial programs. More specifically, manual, semi-automatic, or automatic parallelization can use the outcomes of data-dependence profiling to guide where and how to parallelize in a program. However, state-of-the-art data-dependence profiling techniques consume extremely huge resources as they suffer from two major issues when profiling large and long-running applications: runtime overhead and memory overhead. Existing data-dependence profilers are either unable to profile large-scale applications with a typical resource budget or only report very limited information.
