News/Toolforge Grid Engine deprecation
This page contains information about the deprecation and removal of the Toolforge Grid Engine platform.
What is changing?
The Grid Engine cluster is being decommissioned in accordance with the timeline on this page.
The Toolforge admins are asking tool maintainers to move tools off the grid and report any blocking issues. This work is being tracked on the Phabricator workboard.
- Oct-Dec 2021: Done Release the Toolforge Jobs Framework. Continue working on Toolforge buildpacks. Migrate Son of Grid Engine to Debian Buster.
- Oct-Dec 2022: Done Ask community to begin migrating tools. Collect blocking issues.
- Jan-Mar 2023: Done Add features to support identified blocking issues. Explore Kubernetes a service as potential migration path. Tool migrations continue.
- Apr-Jun 2023: Done Toolforge buildpacks beta. See T267374. Tool migrations continue.
- Jul-Sep 2023: Done Toolforge buildpacks multipack support work. See T325799. Tool migrations continue.
- Oct-Dec 2023: Doing... All Tools are now able to be migrated. Tool migrations continue.
- November 2023: Kickoff grid shutdown process. Notify individual maintainers who still have tools on the grid of shutdown timelines via email, cloud-announce mailing list, and talk pages.
- December 2023: Notify maintainers using
jsuband related tools about shutdown timeline
- 2023-12-14: Tools owned by unresponsive or unreachable maintainers will be stopped
- Jan-Mar 2024: The grid is stopped and the grid infrastructure is deleted
- 2024-02-14: Grid is stopped entirely: All tools stopped, new submissions will no longer be possible
- 2024-03-14: Grid infrastructure is deleted.
What should I do?
You have a couple of options:
- migrate your Toolforge tool to Toolforge Kubernetes.
- simply delete your tool, in case it is not used anymore.
Use case continuity
The following table tracks use case continuity.
|job scheduling||jsub or jstart|| Toolforge jobs
One off jobs or continuous jobs
5 * * * * jsub -once -N name-of-tool $HOME/user/bot.php >/dev/null 2>&1
$ toolforge-jobs run name-of-tool --command ./user/bot.php --image php8.2 --schedule "@hourly"
|web services||webservice||specify an image and 'kubernetes' as the backend||Example:
$ webservice --backend=gridengine start
$ webservice stop $ webservice --backend=kubernetes php8.2 start
|Multi-language tools||Native||Toolforge buildpacks||Some single language tools will need updated or new images (like dotnet)|
Why are we doing this?
As outlined in our series of blog posts, Toolforge is powered by two different backend engines, Kubernetes and Grid Engine. These two backends have traditionally offered different features for tool developers. But as time moves forward we’ve learnt that Kubernetes is the future.

Solutions to common problems
Rebuild virtualenv for Python users / python3: not found
Python virtual environments ("venvs") are tied to the underlying system where they are running. Because of that, you will need to delete and re-create your virtual environments using these instructions.
Tools needing multiple language runtimes
You can build an image for your tool with the dependencies required.
Using mono? See discussion on a Mono specific container phab:T311466
Requires a system library or tool to be present
If you believe this depedency makes sense to have in the base container, file a ticket. For example, mysqldump phab:T254636, resolved.
For other needs, note that buildpack project will support more nuanced and custom container setups.
See Help:Toolforge/Running Pywikibot scripts on how to easily run Pywikibot scripts using the jobs framework.
Delete a tool
Some tools were experiments that are done, others were made obsolete by other tools, some are just things that the original maintainer is tired of caring for. Maintainers can mark their tools for deletion using the "Disable tool" button on the tool's detail page on https://toolsadmin.wikimedia.org/. Disabling a tool will immediately stop any running jobs including webservices and prevent maintainers from logging in as the tool. Disabled tools are archived and deleted after 40 days. Disabled tools can be re-enabled at any time prior to being archived and deleted.
