Introduce a new KEP proposal to allow updating container resource specifications (CPU, memory, GPU, extended resources) for suspended jobs. Key features: - Enable dynamic resource allocation for suspended jobs only - Support CPU, memory, and GPU resource mutations - Include extended resources (nvidia.com/gpu, amd.com/gpu, tpu-v4, etc.) - Allow queue controllers to optimize resource allocation based on cluster conditions - Feature gate: MutableJobPodResourcesForSuspendedJobs - Focus on batch workload optimization scenarios This proposal enables better cluster utilization and cost optimization by allowing queue controllers to adjust job resource requirements before execution based on real-time cluster capacity and resource availability. Particularly valuable for expensive GPU and specialized hardware resources.
