Kurzbeschreibung (Abstract)
The integration of the memory controller on the processor die enables ever larger core counts in commodity hardware shared memory systems with Non-Uniform Memory Architecture properties. Shared memory parallelization with OpenMP is an elegant and widely used approach to leverage the power of such systems. The binding of the OpenMP threads to compute cores and the corresponding memory association are becoming even more critical in order to obtain optimal performance. In this work we provide a method to measure the amount of remote socket memory accesses a thread generates. We use available performance monitoring CPU counters in combination with thread binding on a quad socket Nehalem EX system. For visualization of the collected data we use Vampir.
