Collecting and representing parallel programs with high performance instrumentation

Computer architecture has looming challenges with finding program parallelism, process technology limits, and limited power budget. To navigate these challenges, a deeper understanding of parallel programs is required. I will discuss the task graph representation and how it enables programmers and compiler optimizations to understand and exploit dynamic aspects of the program. I will present Contech, which is a high performance framework for generating dynamic task graphs from arbitrary parallel programs. The Contech framework supports a variety of languages and parallelization libraries, and has been tested on both x86 and ARM. I will demonstrate how this framework encompasses a diversity of program analyses, particularly by modeling a dynamically reconfigurable, heterogeneous multi-core processor.Ph.D
