Inputs of aspect oriented programming for the profiling of C++ parallel applications on manycore platforms

High Performance Computing systems expect applications to leverage the most of their processing power. This need is even more present for applications such as Monte Carlo simulations that require noteworthy CPU time and memory footprint. Optimizing applications is one approach to reduce the consumption of these resources. Before optimizing, it is mandatory to profile the application in order to pinpoint bottlenecks and hot spots. In this paper, we propose an approach to applications profiling based on Aspect Oriented Programming (AOP). We introduce a profiling approach for C++ codes with the pthread library based on free open source software with low overhead, multicore awareness, multi-threading handling, ease of use and quality outputs compared to established profilers. We will present how our prototype, based on an AOP approach proved to be useful and efficient on a test application.
