ref-celery

This package provides celery task generation from Provider and Metric definitions.

CLI tool

The cmip_ref_celery package provides a CLI tool to start a worker instance from a REF metrics provider. This worker instance will listen for tasks related to a provider and execute them. The compute engine worker will then collect the results of these tasks and store them in the database. This allows for the REF to be run in a distributed manner, with multiple workers running on different machines with a centrally managed database.

Usage

For example, to start a worker instance for the cmip_ref_metrics_example package:

ref-celery start-worker --package cmip_ref_metrics_example

This requires the cmip_ref_metrics_example package to be installed in the current virtual environment.

If the cmip_ref package is also installed, the celery CLI command is available via the ref CLI tool. The equivalent command to the above is:

ref celery start-worker --package cmip_ref_metrics_example

Configuration

Each worker instance may not share the same configuration as the orchestrator. This is because the worker may be running on a different machine with different resources available or directories.

Each worker instance requires access to a shared input data directory and the output directory. If the worker is deployed as a docker container these directories can be mounted as volumes.
