This page provides complete, annotated software_config.json examples for common deployment scenarios. Copy the scenario that best matches your deployment and modify as needed.

x86_64 - Slurm + Kubernetes

This example demonstrates a single-architecture full deployment of Slurm(slurm_custom) and Kubernetes(service_k8s) supporting only x86_64 nodes.

Multi-Arch - Slurm + Kubernetes

This example demonstrates a multi-architecture deployment supporting both x86_64 and aarch64 nodes.

x86_64 - Slurm

Deploys a traditional HPC cluster with Slurm scheduling, LDAP, openmpi and ucx. No Kubernetes.

    ]
}

Note

• Every functional_group_name must match an entry in the PXE mapping CSV (see Pxe Mapping File).
• Kubernetes(service_k8s) cluster only supports x86_64 architecture.
• Groups not listed in the JSON receive only base OS packages.

Info

• Software Config -- Full parameter reference.
• PXE Mapping File -- PXE mapping CSV that defines functional groups.
