SUMMARY:Trusted Platform Provisioning for the OpenCHAMI Cluster Management
  Stack
DESCRIPTION:Lucas Ritzdorf (Los Alamos National Laboratory (LANL), Univers
 ity of Washington) and Nicholas Jones, David Allen, and Travis Cotton (Los
  Alamos National Laboratory (LANL))\n\nHigh performance computing (HPC) cl
 usters have traditionally relied on proprietary provisioning and managemen
 t infrastructure. This can be problematic, especially with regard to ongoi
 ng security and maintenance for vendored systems.\n\nAs an alternative to 
 this, the Los Alamos National Laboratory (LANL) leads development of the O
 pen Composable Heterogeneous Application Management Infrastructure (OpenCH
 AMI) stack, which provides a modular suite of size- and platform-independe
 nt cluster management tools. A major barrier to the full deployment of Ope
 nCHAMI at LANL is its lack of authentication for access to sensitive data,
  such as private SSH keys or service tokens. To resolve this, we implement
  and integrate a node authentication system, under which secret configurat
 ion data may be requested only by system processes or authorized users.\n\
 nWe present a containerized microservice-based authentication system for p
 ost-boot compute node configuration, based on the Canonical cloud-init pla
 tform. This system is optimized to minimize its impact on cluster boot spe
 ed.\n\nRegistration Category: Tech Program Reg Pass, Exhibits Reg Pass\n\n
 Session Chairs: Ayesha Afzal (Friedrich-Alexander University, Erlangen-Nur
 emberg; Erlangen National High Performance Computing Center); Sally Elling
