GPU Sharing, Now Native: Cast AI Adds DRA Support
Blog post from Cast AI
Kubernetes GPU clusters often face inefficiencies with a few GPUs working at full capacity while others remain idle, leading to a mismatch between expenditure and value derived from GPU resources. This challenge is exacerbated by the complex and manual configurations required for GPU sharing and management, especially as AI workloads grow. Dynamic Resource Allocation (DRA) changes this landscape by shifting GPU management from static configurations to intent-based allocations, allowing workloads to specify resource needs through resource claims, thus decoupling workload requirements from infrastructure specifics. Cast AI enhances this process by automating the provisioning and scaling of GPU resources to match demand, optimizing costs through intelligent instance selection and spot capacity utilization, and ensuring seamless operation without manual intervention. This approach not only improves efficiency by aligning infrastructure with workload intent but also reduces GPU idle time, ultimately allowing teams to focus more on developing models and applications rather than managing infrastructure. DRA support is currently available for GKE and EKS on Kubernetes 1.34 and above, with AKS support anticipated soon.
