Installation on linux local machine

  • Install virtual environment with Python 2.7
$> pip install virtualenv
$> python -m virtualenv venv2.7
$> . venv2.7/bin/activate
  • Install DarkSkySync
$> git clone git@cosmo-gitlab.phys.ethz.ch:cosmo/darkskysync.git
$> cd darkskysync
$> pip install -r requirements.txt
$> pip install -e .
$> make test
  • install pyCosmo
$> git clone git@cosmo-gitlab.phys.ethz.ch:cosmo/PyCosmo.git
$> cd PyCosmo
$> pip install -r requirements.txt
$> pip install -e .
$> make test
  • install Cpod
$> git clone git@cosmo-gitlab.phys.ethz.ch:cosmo/cpod.git

$> make test

External dependencies

  • HDF5

Download HDF5 the latest version for MUSIC and the version 1.4.4 for Gadget2.

$> gzip --decompress hdf5-1.x.x.tar.gz
$> tar -xvf hdf5-1.x.x.tar
$> cd hdf5-1.x.x
$> mkdir build
$> cd build

Find out the path to mpicc and use it for configuration

$> which mpicc
/usr/bin/mpicc
$> CC=/usr/bin/mpicc ../configure --enable-parallel --prefix=/usr/local/hdf5/1.x.x
$> make
$> make check

Make check may fail at testing cache-api. Continue to install, depending on the installation directory, you might need to be root or use sudo.

$> make install
  • FFTW

Download fftw3 for MUSIC and fftw2 for Gadget2.

$> tar -xzvf fftw-x.x.x.tar.gz
$> cd fftw-x.x.x
$> mkdir build
$> cd build

If you want to install double and single precision.

$> ../configure --enable-type-prefix --enable-threads --enable-mpi --prefix=/usr/local/fftw/x.x.x
$> make
$> make install
$> make clean
$> ../configure --enable-float --enable-type-prefix --enable-threads --enable-mpi --prefix=/usr/local/fftw/x.x.x
$> make
$> make install
  • GSL
$> sudo apt-get libgsl2

or

$> module load gsl
  • MPI library
$> module load open_mpi
  • Music

Download Music ZIP file and refer installation in user guide from https://www-n.oca.eu/ohahn/MUSIC/. Requirements: hdf5-1.10.1, fftw-3.3.7, mpi, gsl

$> cd <installdir>/ohahn-music-12e7b54e7512
