Configuring Bodo Enterprise Edition¶
Bodo Enterprise Edition allows unrestricted use of Bodo on any number of cores. Ensure you have finished Installation before configuring Bodo Enterprise Edition.
Bodo Enterprise Edition requires a license key to run. The key can be provided in two ways:
Through the environment variable
A file called
bodo.licin 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 4 cores.
If you try to run Bodo on more than 4 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
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
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 Installation, we recommend the following steps to automate setting the
BODO_LICENSE environment variable (closely follows these steps):
Ensure that you’re in the correct conda environment.
Navigate to the
$CONDA_PREFIXdirectory and create some additional conda environment activation and deactivation steps:
cd $CONDA_PREFIX mkdir -p ./etc/conda/activate.d mkdir -p ./etc/conda/deactivate.d touch ./etc/conda/activate.d/env_vars.sh touch ./etc/conda/deactivate.d/env_vars.sh
#!/bin/sh export BODO_LICENSE="<COPY_PASTE_THE_LICENSE_HERE>"
#!/bin/sh unset BODO_LICENSE
conda deactivate) and reactivate the
Bodoconda environment (
conda activate Bodo) to ensure that the environment variable
BODO_LICENSEis 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 example.py
For cloud instances, one physical core usually corresponds to two vCPUs. For example, an instance with 32 vCPUs has 16 physical cores.
