SUMMARY:Kubernetes Resource Scaling via Batch Node Conversion on the Anvil
  Supercomputer
DESCRIPTION:Erik Gough and LJ Lumas (Purdue University)\n\nThis lightning 
 talk will explore our approach to reallocating compute nodes in an HPC sys
 tem managed by Slurm, converting them from "batch" nodes to "cloud" nodes 
 within a Kubernetes resource. We developed and implemented these methods o
 n the Anvil ACCESS resource to support large-scale educational and trainin
 g workshops. By temporarily shifting batch nodes to cloud nodes, we overca
 me capacity limitations on Anvil's Kubernetes infrastructure, enabling one
  workshop to scale up to 75 computing sessions, a 3.5x increase over what 
 was possible with their allocation. We will give an overview of Anvil's xC
 AT + masterless puppet configuration management stack and introduce a scri
 pt that facilitates the conversion of HPC batch nodes to Anvil Kubernetes 
 nodes and back, providing flexible resource management through command-lin
 e options. While each institution's software stack is unique, our experien
 ce and guidelines offer a foundation that others can adapt to achieve simi
 lar success in their own environments.\n\nTag: HPC Infrastructure, State o
 f the Practice, System Administration\n\nRegistration Category: Workshop R

 search (NCAR)), John Blaas (Lambda), and Elizabett Hillery (Purdue Univers
 ity)\n\n
