Overview

This pages describes the settings, analysis and experiments presented in the USENIX paper.

The source code is checked in the USENIX ATC '16 branch.

Prerequisites

To launch the analysis or the experiments, you must install:

  • sbt, to compile and create self-running apps.
  • openjdk-7-jdk and openjdk-7-jre, to get java.
  • libpfm-4.6, to get an extended access to hardware counters.
  • bluez and libbluetooth-dev, to use the external PowerSPY power meter.
  • parsec-2.1, NPB-3.3.1, SpecJBB, as workloads used in our paper.

Source code

Several sbt projects, based on PowerAPI, have been developed upon needs.

Each project has its own configuration, and has to be adapted when needed.

HPC events analysis

The source code used during the Learning Phase (cf. Section 3.1) is checked inside the hpc-analysis-default project for Intel or AMD architectures, or the hpc-analysis-arm project for ARM architecture instead.

Process-level Power Monitoring

The source code used for this experiment (cf. Section 5.3) is checked inside the exp-process-level-xeon project.

Adaptive CPU Power Models

The source code used for this experiment (cf. Section 5.4) is checked inside the exp-domain-pmodel-tegra-1c and exp-domain-pmodel-tegra-4c projects.

System Impact on CPU Power Models

The source code used for this experiment (cf. Section 5.5) is checked inside the exp-system-impact-xeon project.

How to build?

All projects are listed in the powerapi-usenix-atc16 project.

  • hpc-analysis-default
  • hpc-analysis-arm
  • exp-domain-pmodel-tegra-1c
  • exp-domain-pmodel-tegra-4c
  • exp-process-level-xeon
  • exp-system-impact-xeon
