OpenHPC on Ansible
summary
OpenHPC moves its orchestration from shell scripts to Ansible, splitting work into reusable roles, making installs idempotent, and integrating with a provisioner and Jenkins to run multi-dimensional test matrices (different OS, kernels, interconnects, node types). Work is already tested on x86_64 and aarch64, replaces fragile document-generated scripts, and claims to have reduced install time to three hours from a week. Next steps: upstream roles, expand OS and network support, and automate post-install tests.
