October 2025 (2025-10) performance summary for epam/cloud-pipeline: Delivered a new SLURM MaxArraySize Configuration feature to improve cluster job management and scalability; enabled via environment variable CP_CAP_SLURM_MAX_ARRAY_SIZE, with logic to append MaxArraySize to slurm.conf when set, enabling control over the maximum number of jobs in a Slurm job array. This change enhances resource planning and scheduling predictability across clusters. Major bugs fixed: none reported this month. Overall impact: improved cluster flexibility, reduced manual config, and clearer governance of job arrays. Technologies demonstrated: Slurm configuration, environment-variable-based feature flags, config automation, and traceability via commits. Reference commit: a70f78452e007409c79e5a52996e55204c636102 (includes #4111). Repo: epam/cloud-pipeline.

In August 2025, delivered the Cross-Region Worker Run Rescheduling feature for epam/cloud-pipeline, enabling restarts of worker runs in a different region. The feature is controlled by CP_CAP_RESCHEDULE_WORKER_RUN or system preference launch.run.reschedule.worker.enabled, and includes the shouldRescheduleWorker function to encapsulate rescheduling logic. This work is anchored by commit 84202c88f0b6b8c945d482da1ed15165f79e0d94 with the message 'Update Run Shift Policy: Allow restarting a worker run (#4054)'. No major bugs fixed this month. Overall impact: increased resilience and operational flexibility for cross-region workloads, reducing manual intervention and downtime risk. Technologies/skills demonstrated: backend feature development, flag-driven configuration, policy-driven changes, and refactoring introducing modular rescheduling logic.
