Installing a WMT executor
A WMT executor, part of the CSDMS Web Modeling Tool, runs standalone or coupled model components on a computational resource.
Requirements:
- An internet-accessible MacOSX or Linux computational resource
git
Installation directory
Start by selecting an install directory for the WMT executor on the computational resource.
The installation directory needs to be accessible to all users.
For example, on the CSDMS HPCC, beach, WMT executors are installed in /home/csdms/wmt.
Change to the install directory you've selected and define a shell variable for future use.
cd /home/csdms/wmt mkdir _testing && cd _testing install=$(pwd)
Install the CSDMS toolchain
Install a local Python distribution for use by the executor. CSDMS IF recommends miniconda, a minimal distribution based on the Anaconda Python distribution.
curl http://repo.continuum.io/miniconda/Miniconda-latest-Linux-x86_64.sh -o miniconda.sh bash ./miniconda.sh -f -b -p $install/conda export PATH=$install/conda/bin:$PATH
Replace "Linux" with "MacOSX" in the curl statement above
if installing on a Mac.
Use the Anaconda package manager, conda,
to install a set of packages used by the executor.
conda install ipython numpy scipy netcdf4
(Although ipython isn't required, it's handy for debugging.)
Using conda
and the CSDMS Anaconda channel,
install cca-bocca, which should fetch and install
several dependencies for the CSDMS toolchain,
including cca-spec-babel, ccaffeine, and cca-bocca.
conda install -c csdms cca-bocca
Clone and install pymt,
using the changes from the mcflugen/fix-for-new-bmi branch.
(The latest changes aren't yet in the CSDMS 'dev' channel.)
mkdir opt && cd opt git clone https://github.com/csdms/pymt cd pymt git branch mcflugen/fix-for-new-bmi git checkout mcflugen/fix-for-new-bmi git pull origin mcflugen/fix-for-new-bmi python setup.py develop
To aid debugging, we recommend installing with "develop" for this and all Python packages built from source.
