Summary
👤
Senior🎓
Top SchoolBill Glick is a Senior System Engineer based in Champaign, IL, with two decades of hands-on experience operating large-scale HPC and research clusters and nine years in his current focused role at NCSA. He specializes in Slurm orchestration, bare-metal provisioning with xCAT/Warewulf, and automation-at-scale using Ansible paired with CI/CD pipelines to deliver repeatable, auditable infrastructure and sub-30-minute reprovision times for 500+ nodes. Bill led a major migration from Puppet/Foreman to Ansible + Semaphore with gated validations, built a Slurm maintenance framework for rolling drains and decommissions, and implemented SSH/PAM/sudo hardening that balanced security with low user friction. Known for translating complex operational needs into lifecycle standards and runbooks, he drives predictable cluster refresh cycles and zero-surprise outages through cross-team coordination and training. Beyond day-to-day ops, he contributes to institutional enablement via an internal Ansible User Group and operational knowledge bases, and has supported national-scale science projects under hardware and data pressure.
