abstract = {Optimization of energy consumption is a key issue for
future HPC. Evaluation of energy consumption requires a
fine-grained power measurement. Additional useful
information is obtained when performing these measurements
at component level. In this paper we describe a setup which
allows to perform fine-grained power measurements up to a 1
ms resolution at component level on IBM POWER (IBM and POWER

machines. We further developed a plug-in for VampirTrace
that allows us to correlate these power measurements with
application performance characteristics, e.g. obtained by
hardware performance counters. This environment enables us
to generate both power and performance profiles. Such
profiles provide valuable input to develop future strategies
for improving workload-driven energy usage per performance.
We show in comparison with power profiles of coarser
granularity that these fine-grained measurements are
necessary to capture the dynamics of power switching.},
