* Agenda
* Slurm HA
* Dynamic nodes
* Open floor
* Release policy
* Two tentative release policies.
* This cycle: Charmed Slurm
* Next cycle: Charmed HPC
* What’s the difference?
* Charmed Slurm is infrastructure. You get the workload scheduler with all the fancy integrations for observability and scale up and down, but you’re responsible for providing application stack and managed identities.
* Charmed HPC is “managed applications” + Charmed Slurm. Charmed HPC is the full application suite with managed identity and workload support.
* Skeleton of published release policy notes:
* Outline
* What is contained within this page, summary of content, where to go announcements tracking.
* Foresight: Link to upgrade instructions once we actually support upgrades.
* Recent releases with support lifecycle.
* Upcoming release roadmap (no target date cause that’s pressure)
* Release and support policy
* Major release (new version of Slurm, breaking changes, new base OS)
* Minor release (new features, but no breaking changes)
* Patch release (bug and security fixes)
* Include note - “plz `juju refresh` if you want the latest security and bug fix updates. Otherwise die”
* Foresight: Feature deprecation
* What’s new in Charmed Slurm __?
* High-level overview of new features/major changes.
* Notable bug fixes.
* Link to more in-depth release notes page
* Security Policy
* Link to the general Charmed Slurm security policy.
* Skeleton of “in-depth” release notes page.
* Summary of what’s new in the release.
* Summary of requirements to deploy Charmed Slurm
* New features + improvements (if any)
* Known issues
* Patched CVEs
* Bug fixes (link to issues on GitHub)
* Upgrade instructions (if any)
* How do we automate this so we do not become professional Markdown programmers?
* Tie issues to release milestones
* Already have the issues tags + types for categorization
* Make sure CVEs are accurately tracked within the project.
* Subscribe to Slurm security mailing list if there is one.
* New features - document via specs.
* “Release policy”
* Something internal to the team, not necessarily something we need to make publicly available. Can live within a spec, but doesn’t need to go on RTD.
Skeleton
* What’s included in a stable release?
* List supported artifacts with link to source code + issue tracker
* Table outlining release structure.
* E.g. stable release of the Slurm charms are published to 25.04/stable on Charmhub
* ^ Mirror this bit in the release notes. E.g. how do you actually pull Charmed Slurm 25.04
* PPA to get supported Slurm packages.
* Any Terraform plans for reference deployment (maybe, homies could just pull from the correct channel)
* How long do we commit to supporting a release?
* 18 months
* When do we release?
* A month after the newest version of Slurm is published?
* Infrastructure for supporting releases.
* Already have the publishing + test pipeline
* Create Git branches for every major version of Slurm.
Merge PR against the relevant feature branch and bubble up from there.
Nice to have: GitHub bot that enables us to promote charms directly from call-for-testing issues.

* Dynamic compute node spec: {%preview https://hackmd.io/@ubuntu-hpc/SJU0Xk0Qeg %}
* Currently working on this specification to introduce dynamic compute nodes in Charmed HPC. This will replace the current way we enlist compute nodes in Charmed HPC, so please offer your input.
* Forseen benefits include:
> _See spec for full description of benefits_ :eyes:
* No more _service.py_ wrapper for the slurmd daemon.
* Compute node configuration - e.g. `NodeName=... Gres=...` - will no longer be tracked in integration data.
* Node state will be controlled directly using `scontrol` rather than through integration data updates. E.g. `node-configured` will call `scontrol update nodename=<node name> state=up` rather than wait for `RelationChanged` events to be handled.
* __This will greatly simplify how we manage Slurm's configuration in the charms, and it will make it easier for us to add new features to the slurmd/slurmctld charms.__
* Open floor
* Public specs for new features and major changes.

## January 29th, 2025
* Agenda
* Status updates:
* Maintenance work (CI)
* Charmcraft 3.3.2 causing integration test failures. Issue filed and raised with the team.
* Identity
* SSSD operator changes merged
* Now integrates with glauth-k8s charm supported by Canonical identity team
* Filesystem client + Lustre
* Azure does not offer packages for Noble for Lustre
* Whamcloud provides 24.04 packages but only for a specific (older) kernel version
* Could package Lustre ourselves with DKMS support but incurs maintainability costs.
* Working on resolution.
* Documentation
* Updates have been made: GPU, filesystem, etc.
* Canonical Open Documentation Academy (CODA) updates coming
* Infiniband
* PR in review. Changes being worked on.
* Discussions:
* Arif on Infiniband subnet management:
* "Is this handled by Azure?" (Yes, Azure handles it behind the scenes)
* Recommendation ~5 years ago was to run OpenSM on metal for larger clusters and not rely on the switches to do subnet management
* Running OpenSM on the controller/slurmctld node may be an option when we get there
* Introductions from Bennett Hunter, University of Chicago HPC cluster manager

## January 22th, 2025
* Agenda
* Status updates:
* Maintenance work
* Identity
* Filesystem client + Lustre
* Documentation
* Infiniband
* Discussions:
* Infiniband detection
* Dominic: Should we install rdma-core by default on slurmd? Would allow us to autodetect Infiniband without much problems.
* Jason: It would be good to first check what can we do using kernel APIs
* Dominic: I'm worried that we won't be as exhaustive as the people maintaining a specialized library to do that.
* Jason: Yeah, maybe that's true. It would be bad to have a double negative where the autodetection code didn't detect IB but the node does have it.
* DOCA OFED vs default kernel drivers
* James: What is the difference between the default drivers and DOCA OFED? Wasn't there a discussion related to that?
* Jason: Yeah, we had the same question. It seems like DOCA OFED has some additional patches and optimizations that aren't included by the default drivers. However, the default drivers are signed and easy to install, so it frees us from the troubles of having to e.g. pass additional parameters to Juju.

## January 15th, 2025

* Agenda
* Status updates:
* Filesystem work
* GPU work
* Identity
* Documentation
* Discussions:
* Should `app_name` be a required argument in our charm Terraform modules, or should we just supply the charm name as the default application name? E.g. application name for `slurmctld` charm is "slurmctld" if an app_name is not supplied to Terraform.
* Set charm name as default to have feature parity with Juju CLI.

## January 8th, 2025

* Agenda
* Happy new year! :tada:
* Status updates:
* Filesystem work
* Bug fixes for inconsistencies in Python 3.9 -> 3.12.
* Working on non-Juju-handled file system support.
* Expecting merged within the next day or so.
* Lustre up next!
* Identity
* Bug with sharing CA certificates: https://github.com/canonical/glauth-k8s-operator/issues/84
* GPUs
* PR open: https://github.com/charmed-hpc/slurm-charms/pull/57
* Before merge, looking to move some functionality into `slurmutils`, add dependencies into the charm (rather than apt installing them), and do some refactoring.
* Discussions
* Arif: from a support perspective, allowing custom drivers (not from archive) can create complications. Possible approaches: allow configuration of a known source for drivers, e.g. a known PPA or other deb repo.
