Introduction

Recent generations of the Intel® Xeon® family processors allow configurations where:

1. Turbo Boost can be enabled on a per-core basis.
2. Some cores can be given a higher base frequency than others

Overview

The scripts provided are as follows:

power.py allows the user to adjust the frequencies and Turbo-Boost availability on a core-by-core basis. This script allows the adjustment of P-states, C-states and Turbo-Boost.

sst_bf.py allows the user to confure the system for Intel® Speed Select Technology - Base Frequency (Intel® SST-BF). This allows some cores to run at a higher base frequency than others.

pwr.py a python library which can be imported into an application, to measure/modify core frequencies of a CPU to utilize Intel® Speed Select Technology.
