Jan 1, 2026January 2026 (2026-01) monthly summary for cedana/cedana. Focused on expanding test automation, improving CI reliability, and stabilizing resource management. Delivered a Kubernetes testing framework with GPU/CPU workloads (including a manual k8s testing script, flexible tag filtering, and an option to disable io_uring for compatibility). Added AI-generated failure summaries with Slack reporting for faster triage. Extended SLURM plugin registry and integrated Karpenter into CI for improved spot-instance resilience during Kubernetes testing. Introduced a BATS test suite for large CPU workloads to validate CI coverage. Major bug fix: Nebius nightlies GPU memory sizing and daemon memory stability, with a rollback of shared memory changes to maintain stability. Business value: more reliable testing, faster debugging, scalable resource management, and stronger reporting for data-intensive workloads.
