Creating batches

Once the list of datasets is collated a number of batches must be created:

$ python roocs_utils/inventory/cli.py create-batches -p c3s-cmip6

The option -p is required to specify the project.

Creating inventory records

Once the batches are created, the inventory maker can be run - either locally or on lotus. The settings for how many datasets to be included in a batch and the maximum duration of each job on lotus can also be changed in roocs_utils/etc/roocs.ini.

Each batch can be run idependently, e.g. running batch 1 locally:

$ python roocs_utils/inventory/cli.py run -p c3s-cmip6 -b 1 -r local

or running all batches on lotus:

$ python roocs_utils/inventory/cli.py run -p c3s-cmip6 -r lotus

This creates a pickle file containing an ordered dictionary of the inventory for each dataset. It also creates a pickle file for any errors.

Viewing records and errors

To view the records:

$ python roocs_utils/inventory/cli.py list -p c3s-cmip6

and to see any errors:

$ python roocs_utils/inventory/cli.py show-errors -p c3s-cmip6

To just get a count of how many datasets have been scanned:

$ python roocs_utils/inventory/cli.py list -p c3s-cmip6 -c

Writing the inventory

The final command is to write the inventory to a yaml file. There are 2 options for this.

$ python roocs_utils/inventory/cli.py write -p c3s-cmip6 -v files

writes the inventory file c3s-cmip6-inventory-files.yml and includes the file names for each dataset:
