A Data Structure Oriented Monitoring Environment for Fortran OpenMP Programs

This paper describes a monitoring environment that enables the analysis of memory access behavior of applications in a selective way with a potentially very high degree of detail. It is based on a novel hardware monitor design that employs an associative counter array to measure data structure related information at runtime. A simulator for this hardware monitor is implemented, providing the capability of on-thefly simulation targeting shared memory systems. Layers of software are constructed to operate and utilize the underlying hardware monitor, thus forming a complete monitoring environment. This environment is useful to help users to reason about optimizations based on data reorganization as well as on standard loop transformations.
