This pages describes the settings, analysis and experiments presented in the JSS submission.
The source code is checked in the JSS'18 folder.
To launch the analysis or the experiments, you must install:
-
sbt, to compile and create self-running apps. -
openjdk-7-jdkandopenjdk-7-jre, to get java. - libpfm-4.6, to get an extended access to hardware counters.
-
bluezandlibbluetooth-dev, to use the external PowerSPY power meter. - parsec-2.1, NPB-3.3.1, SpecJBB, as workloads used in our article.
Several sbt projects, based on PowerAPI, have been developed upon needs.
Each project has its own configuration, and has to be adapted when needed.
The source code used during the Learning Phase is checked inside the hpc-analysis-default project for Intel or AMD architectures, or the hpc-analysis-arm project for ARM architecture instead.
The source code used for this experiment is checked inside the exp-process-level-xeon project.
The source code used for this experiment is checked inside the exp-domain-pmodel-tegra-1c and exp-domain-pmodel-tegra-4c projects.
The source code used for this experiment is checked inside the exp-system-impact-xeon project.
- Clone the repository: `git clone https://github.com/Spirals-Team/powerapi.git``
- Checkout the JSS branch:
git checkout research/jss-18 - Go to the parent sbt project:
cd powerapi-jss-18 - Launch sbt:
sbt, and choose one of the project listed below:> project ... - Create a self-running app:
universal:packageZipTarball - Get the app packaged as a tarball, extract it, configure it (
conf/) and use it (sudo ./bin/...)
All projects are listed in the powerapi-jss-18 project.
