summary
Claim: a Kubernetes pod with nodeSelector: "EuroHPC" and SLURM/MPI settings in pod annotations runs as a job on EuroHPC supercomputers. Implementation uses interLink built on Virtual Kubelet, where a simple OpenAPI REST plugin translates pod specs into SLURM jobs, authenticates via OpenID Connect, and exposes overlay networking so pod IPs, logs, and services behave like in-cluster. Demo shows a Ray cluster for distributed ML training and GenAI workloads running on Leonardo and Vega; code is a thin, pluggable layer now in the Cloud Native sandbox.
