Query: Towards Modeling Energy Consumption of Xeon Phi   In the push for exascale computing, energy efficiency is of utmost concern.
System architectures often adopt accelerators to hasten application execution
at the cost of power. The Intel Xeon Phi co-processor is unique accelerator
that offers application designers high degrees of parallelism, energy-efficient
cores, and various execution modes. To explore the vast number of available
configurations, a model must be developed to predict execution time, power, and
energy for the CPU and Xeon Phi. An experimentation method has been developed
which measures power for the CPU and Xeon Phi separately, as well as total
system power. Execution time and performance are also captured for two
experiments conducted in this work. The experiments, frequency scaling and
strong scaling, will help validate the adopted model and assist in the
development of a model which defines the host and Xeon Phi. The proxy
applications investigated, representative of large-scale real-world
applications, are Co-Design Molecular Dynamics (CoMD) and Livermore
Unstructured Lagrangian Explicit Shock Hydrodynamics (LULESH). The frequency
experiment discussed in this work is used to determine the time on-chip and
off-chip to measure the compute- or latencyboundedness of the application.
Energy savings were not obtained in symmetric mode for either application.
