Siwenna: wmt-testing

Instructions for installing and configuring a WMT executor on siwenna.

--Mpiper (talk) 12:33, 22 February 2018 (MST)

Install Python

Install a Python distribution to be used locally by the executor. We like to use Miniconda.

mkdir -p /home/csdms/wmt/_testing && cd /home/csdms/wmt/_testing
curl https://repo.continuum.io/miniconda/Miniconda2-latest-Linux-x86_64.sh -o miniconda.sh
bash ./miniconda.sh -f -b -p $(pwd)/conda
export PATH=$(pwd)/conda/bin:$PATH
root=$(pwd)

If working with an existing Python install, be sure to update everything before continuing:

conda update --all

Install the CSDMS software stack

Using the csdms-stack conda channel (the Bakery) install the CSDMS software stack, including several pre-built components, with the `csdms-stack` metapackage.

conda install csdms-stack -c csdms-stack -c defaults -c conda-forge

This metapackage currently includes

• pymt
• cca-tools
• csdms-child
• csdms-sedflux-3d
• csdms-hydrotrend
• csdms-permamodel-ku
• csdms-permamodel-frostnumber
• csdms-permamodel-kugeo
• csdms-permamodel-frostnumbergeo
• csdms-brake
• csdms-pydeltarcm

Next, install `wmt-exe` from source.

mkdir -p $root/opt && cd $root/opt
git clone https://github.com/csdms/wmt-exe
cd wmt-exe
python setup.py develop

Optionally install the `babelizer`, in case a component needs to be built from source.

conda install -c csdms-stack babelizer

Optionally install IPython for testing.

conda install ipython

When running IPython remotely on siwenna, it's helpful to set

export MPLBACKEND=Agg

Install and test CSDMS components

Each section below describes how to install and test a particular CSDMS component.

Note that the ILAMB component from the Bakery won't work because it's built against `pymt=0.2`; in particular, my BMI for ILAMB is incompatible with the `model_metadata` package in newer versions of PyMT.

HydroTrend

Hydrotrend is included in the `csdms-stack` metapackage. Test it by starting a Python session in $root/test and executing the setup and IRF methods.

from pymt.components import Hydrotrend

comp = Hydrotrend()
comp.get_component_name()
# args = comp.setup('.')
# comp.initialize(*args)
comp.setup('.')
comp.initialize(None)
comp.get_start_time()
comp.get_end_time()
comp.get_current_time()
comp.update()
comp.finalize()

Permamodel

Permamodel is included in the `csdms-stack` metapackage. Test a component by starting a Python session in $root/test and executing the setup and IRF methods.

from pymt.components import FrostNumberModel

comp = FrostNumberModel()
comp.get_component_name()
# args = comp.setup('.')
# comp.initialize(*args)
comp.setup('.')
comp.initialize('frostnumber_model.cfg')
comp.get_start_time()
comp.get_end_time()
comp.get_current_time()
comp.update()
comp.finalize()
