The performance of high performance computing applications depends highly on how they are implemented. However, their runtime behavior is tightly coupled with the resources they are allocated such as in which cores the application threads run or in which memory devices their memory space is placed. Thus, depending on their characteristics, applications may exhibit more affinity to specific types of processors or perform better in a given architecture. In this paper, mptrace, a novel PIN-based tool aiming at profiling the applications physical memory usage is presented.
