SECURITY · HOMELAB · HPCThree tracks, one queue: security challenge design, the homelab this site runs on, and a small HPC lab. LIVE means up and verified; PLANNED means next, and it goes LIVE when I do.
r740xd-prod
HOMELABDell PowerEdge R740xd, the main server running every production service, this site included: Proxmox VE, OPNsense firewall, 6-VLAN segmented network, multi-tier ZFS, Traefik v3 + Keycloak SSO, Netbird mesh VPN, Proxmox Backup Server, Prometheus / Grafana / Loki.
r240-bench
HOMELABDell PowerEdge R240, a dedicated test bench for regular VM and network experiments, kept apart from production.
slurm-basics
HPCSlurm mini-cluster built: controller, login node and four compute VMs across two partitions, on Proxmox. Scheduling only, no GPU.
VM-based and scheduling-focused, not a GPU compute cluster. Target playground: LANL's public Darwin cluster (CCS-7).
lustre-storage
HPCUnderstand and test parallel storage (Lustre).
VM-based and scheduling-focused, not a GPU compute cluster. Target playground: LANL's public Darwin cluster (CCS-7).
mpi-hello
HPCFirst MPI programs on the home cluster.
