Sep 1, 2025September 2025 monthly summary for Azure/azhpc-images. Focused on delivering improvements that increase platform readiness, security, and maintainability while stabilizing deployments on Alma9.x. Key features delivered: - Alma9.6 testing introduced with fixes for Alma9 compatibility to enable reliable Alma9.6 support. - Codebase formatting standardization implemented to unify style and tooling across the repository. - Upgraded components to the latest versions to reduce technical debt and align with security/feature roadmaps. Major bugs fixed: - AOCL compatibility and u24 version updates to ensure AOCL works with current toolchains. - Lustre integration fixes across waagent, toolkit, and related components; Lustre is temporarily omitted to stabilize delivery. - AZNFS issues resolved, improving NFS-based workloads. - AIOHTTP vulnerabilities patched (USN-7642-1). - GDRCOPY version alignment to prevent runtime mismatches. - Packaging/distribution fixes and cleanup, including removal of deprecated aiphttp components. - Cloud-init/waagent/config adjustments and CUDA path/sKU customizations to improve deployment reliability. Overall impact and accomplishments: - Improved Alma9.6 deployment readiness and compatibility, enabling faster rollouts. - Strengthened security posture with vulnerability remediation and dependency upgrades. - More reliable packaging and distribution, reducing friction in downstream deployments. - Cleaner, maintainable codebase through standardized formatting and removal of deprecated components. Technologies/skills demonstrated: - Linux distributions testing (Alma9), compatibility testing, and bug triage - Dependency management and version control discipline (upgrades, fixes, and cleanup) - Security remediation (AIOHTTP patch, USN advisory) and vulnerability management - CI/CD hygiene, cloud-init/waagent configurations, and packaging engineering
