All Platforms System Requirements

  • CMOR 3.9.0 on conda-forge has support for Python 3.9, 3.10, 3.11, and 3.12.

  • Anaconda

  • Make sure anaconda is in your PATH (assuming ananconda is installed in ${HOME}/anaconda)

    export PATH=${HOME}/anaconda/bin:${PATH} # for [ba]sh
setenv PATH ${HOME}/anaconda/bin:${PATH} # for [t]csh

Installing CMOR and PrePARE

  • Run the following commands

    # install cmor
# ------------------------------------------------
conda create -n CMOR -c conda-forge cmor
conda activate CMOR

# Clone the CMIP6 table to your working directory.
# ------------------------------------------------
mkdir CMIP6_work
cd  CMIP6_work
git clone https://github.com/PCMDI/cmip6-cmor-tables.git

# Note:
# -----------------------------------------------------------
# UDUNITS2_XML_PATH is set automatically by activating CMOR. 
# export UDUNITS2_XML_PATH=${CONDA_PREFIX}/share/udunits/udunits2.xml
#

Testing

  • Run the full test suite for C, Fortran, and Python

    Clone CMOR code and CMIP6 tables

    # Clone the CMOR repository to your working directory.
# ------------------------------------------------
git clone https://github.com/PCMDI/cmor.git
cd cmor

# Update the CMIP6 tables submodule.
# ------------------------------------------------
git submodule init
git submodule update

    Install gcc and gfortran and linking environment variable

    Linux:

    conda install -n CMOR -c conda-forge gcc_linux-64 gfortran_linux-64
export LDSHARED_FLAGS="-shared -pthread"

    Mac:

    conda install -n CMOR -c conda-forge clang_osx-64 gfortran_osx-64
export LDSHARED_FLAGS=" -bundle -undefined dynamic_lookup"

    Build and run tests

    # Set prefix for configure step.
# ------------------------------------------------
export PREFIX=$(python -c "import sys; print(sys.prefix)")

# Configure the Makefile.
# ------------------------------------------------
./configure --prefix=$PREFIX --with-python --with-uuid=$PREFIX --with-json-c=$PREFIX --with-udunits2=$PREFIX --with-netcdf=$PREFIX  --enable-verbose-test

# Run the tests with the Makefile (without rebuilding CMOR).
# ------------------------------------------------
make test -o cmor -o python

Conda environment

Obtaining Nighlty builds

  • Create a dedicated environment for nightly (in between releases code): 
    conda create -n [YOUR_ENV_NAME_HERE] -c pcmdi/label/nightly -c conda-forge cmor
source activate [YOUR_ENV_NAME_HERE]
  • Create an environment with compilers for development/testing: 
    conda create -n [YOUR_ENV_NAME_HERE] -c pcmdi/label/nightly -c conda-forge cmor gcc_linux-64 gfortran_linux-64
source activate [YOUR_ENV_NAME_HERE]
