Configuring Bodo Enterprise Edition

Bodo Enterprise Edition allows unrestricted use of Bodo on any number of cores. Ensure you have finished Installing Bodo Community Edition before configuring Bodo Enterprise Edition.

License Key

Bodo Enterprise Edition requires a license key to run. The key can be provided in two ways:

  • Through the environment variable BODO_LICENSE

  • A file called bodo.lic in the current working directory

In both cases, the file or environment variable must contain the key exactly as provided.

If Bodo cannot find the license (environment variable does not exist or is empty, and no license file is found), you will only be able to run Bodo on up to 8 cores. If you try to run Bodo on more than 8 cores and if Bodo cannot find the license (the environment variable does not exist or is empty, and no license file is found), it will exit with the Bodo license not found error.

If the key content is invalid Bodo will exit with the Invalid license error. This typically means that the key is missing data or contains extraneous characters. Please make sure the license file has not been modified, or that the environment variable contains the key verbatim. Note that some shells might append extra characters when displaying the file contents. A valid way to export the key is this:

export BODO_LICENSE=`cat bodo.lic

Automated BODO_LICENSE environment variable Setup

You can automate setting of the BODO_LICENSE environment variable in your ~/.bashrc script (or the ~/.zshrc script for macOS) using:

echo 'export BODO_LICENSE="<COPY_PASTE_THE_LICENSE_HERE>"' >> ~/.bashrc

For more fine grained control and usage with the Bodo conda environment as created during Installing Bodo Community Edition, we recommend the following steps to automate setting the BODO_LICENSE environment variable (closely follows these steps):

  1. Ensure that you’re in the correct conda environment.

  2. Navigate to the $CONDA_PREFIX directory and create some additional conda environment activation and deactivation steps:

    mkdir -p ./etc/conda/activate.d
    mkdir -p ./etc/conda/deactivate.d
    touch ./etc/conda/activate.d/
    touch ./etc/conda/deactivate.d/
  3. Edit ./etc/conda/activate.d/ as follows:

  4. Similarly, edit ./etc/conda/deactivate.d/ as follows:

    unset BODO_LICENSE
  5. Deactivate (conda deactivate) and reactivate the Bodo conda environment (conda activate Bodo) to ensure that the environment variable BODO_LICENSE is automatically added when the environment is activated.

Using MPI in Clusters with Bodo Enterprise Edition

MPI can be configured on clusters easily. The cluster nodes need to have passwordless SSH enabled between them, and there should be a host file listing their addresses (example tutorial here).For best performance, MPI usually needs to be configured to launch one process per physical core. This avoids potential resource contention between processes (due to high efficiency of MPI). For example, a cluster of four nodes, each with 16 physical cores, would use 64 MPI processes:

$ mpiexec -n 64 python

For cloud instances, one physical core usually corresponds to two vCPUs. For example, an instance with 32 vCPUs has 16 physical cores.
