Philharmonic is a geo-distributed cloud simulator written in Python. It compares the energy and cost efficiency of different dynamic VM scheduling algorithms in a realistic environment with real-time electricity prices and temperature-dependent cooling. It offers a simple OpenStack controller that actually pauses and/or suspends instances based on the electricity prices, although this experimental part is not the focus of development any more.
If you have a recent Python 2 (not all of the code would work on Python 3), pip and virtualenv set up, install the necessary dependencies within a cloned repository.
pip install -e .
Or if you don't have the repository cloned and just want to try it out you can directly install from the git repository.
pip install -e git+ssh://[email protected]:philharmonic/philharmonic.git#egg=philharmonic
Both of these commands will automatically pull in all the dependencies, but if you want to use your system's package manager to speed up the installation a bit, read below.
Ubuntu dependencies
sudo apt-get install python-numpy python-pandas python-matplotlib \
python-scipy python-pysnmp4 python-soappy python-twisted \
python-twisted-web
or
pip install -r requirements.txt
Note: creating a virtualenv with --system-site-packages and still
installing the scientific packages via apt-get is much faster as no
compiling is necessary.
Before using the package, it is necessary to build the Cython sources.
python setup.py build_ext --inplace
Philharmonic is used in the terminal through a command line interface (CLI).
First it is necessary to generate the input datasets (optionally setting
the --conf flag - see below).
python simulate.py inputgen [--conf=philharmonic.settings.ga]
Then the simulation can be started. To use the default settings:
python simulate.py run
The main settings to all the subcommands are defined through a config file
passed to the CLI. The config file is specified in Python and can inherit
and override properties from other config files. To pass different settings
use the --conf flag, e.g.:
python simulate.py run --conf=philharmonic.settings.ga
This configuration sets various simulator and scheduler settings, as well as the locations of various input comma separated value (CSV) files and output directories.
