Underlying projects and dependencies

Charmed HPC is a modular composition of underlying projects and dependencies. The tables below list the projects, charms, integrations, libraries, packages, and deployment plans that drive and manage the operations of a Charmed HPC cluster.

Projects

The underlying projects that compose Charmed HPC can be divided into three categories.

Core

Core projects are projects that are maintained directly as part of Charmed HPC.

project	source code	bug report
slurm-charms	Source	Issue tracker
filesystem-charms	Source	Issue tracker
sssd-operator	Source	Issue tracker
slurmutils	Source	Issue tracker
hpc-libs	Source	Issue tracker
charmed-hpc-terraform	Source	Issue tracker

Dependencies

Dependency projects are projects that are required for Charmed HPC to operate successfully, but are not maintained directly as part of Charmed HPC.

project	source code	bug report
juju	Source	Issue tracker
mysql	Source	Issue tracker
mysql-router	Source	Issue tracker
traefik-k8s	Source	Issue tracker
glauth-k8s	Source	Issue tracker
postgresql-k8s	Source	Issue tracker

Optional dependencies

Optional dependency projects are projects that are not required for Charmed HPC to operate successfully, but can enhance the operations of a Charmed HPC cluster. Like dependency projects, optional dependency projects are not maintained directly as part of Charmed HPC.

project	source code	bug report
grafana-agent	Source	Issue tracker
grafana-k8s	Source	Issue tracker
prometheus-k8s	Source	Issue tracker
alertmanager-k8s	Source	Issue tracker
loki-k8s	Source	Issue tracker
catalogue-k8s	Source	Issue tracker

Charms

Charmed HPC is composed of both Machine and Kubernetes charms.

Several of the charms include configuration options that are useful for customizing Charmed HPC deployments. These charms can also include actions that are useful for running common lifecycle operations on a deployed Charmed HPC cluster.

Note

A charm does not have any modifiable configuration options or runnable actions if a table cell below is blank.
