Highlights include delivering Slurm deployment stability via MaxNodeCount cap, centralizing HTC scheduler parameters in blueprint config, upgrading slurm-gcp to 6.9.1, and ensuring MIGs are deleted before compute-node removal. Added DWS Flex integration tests with arbitrary blueprint loading and moved h4d-vm tests to us-central1 for faster, more reliable execution. Extended GPU testing to include B200 GPUs and adoption of the future reservation workflow for better resource planning in ML workloads. These workstreams improved deployment reliability, reduced test execution time, and expanded hardware coverage while tightening dependency management.

Oct 1, 20242024-10 Monthly Summary for GoogleCloudPlatform/cluster-toolkit. Focused on feature delivery around Slurm reservations on GCP. Key feature delivered: Future reservations support for Slurm on GCP nodeset. This enables a new input variable for future reservation details and refines the instance-property logic to correctly associate and manage nodes with future reservations, including a guard to prevent resumption when the reservation is not active. This work lays the groundwork for planned capacity and cost management in cluster provisioning. Major bugs fixed: None explicitly reported this month; the effort was feature-driven with emphasis on robustness of reservation handling. Overall impact and accomplishments: Improved capacity planning accuracy and cost visibility for GCP-based Slurm clusters; enhanced reliability of reservation-based scaling and reduced risk of unintended node resumptions. Technologies/skills demonstrated: Slurm integration on GCP, input-driven configuration patterns, reservation-state handling, and clear change traceability via commit b18d453c50be4ef5b7a163e9c3d0ba3241813bf7.
