Before revision:  We present the four tools that comprise LIKWID and show the influence of thread pinning on performance using the well-known OpenMP STREAM triad benchmark . On the example of a stencil code specifically optimized to utilize cache topology we demonstrate the usage of likwid-pin and likwid-perfCtr .
After revision:  We present the four tools that comprise LIKWID and show the influence of thread pinning on performance using the well-known OpenMP STREAM triad benchmark , and use the affinity and hardware counter tools to study the performance of a stencil code specifically optimized to utilize cache topology we demonstrate the usage of likwid-pin and likwid-perfCtr .
