Green Contexts
A GPU resource partitioning mechanism introduced by NVIDIA that allows developers to define SM (Streaming Multiprocessor) usage boundaries for different logical components within a single process via API, enabling resource isolation and fine-grained scheduling control between latency-sensitive and throughput-intensive tasks.
Timeline (last 90 days)
NVIDIA Green Contexts is a resource partitioning mechanism that allows developers to programmatically control GPU compute resource allocation within a single process, establishing SM usage boundaries for different logical components.
The core idea of Green Contexts is to perform a soft partitioning of GPU compute resources, allowing developers to explicitly specify how many SM resources a given portion of the workload uses.
Green Contexts share similar goals with MIG and MPS (improving GPU utilization and isolation) but differ in positioning: MIG is a hardware physical partition with the strongest isolation but lower flexibility, MPS targets multi-process sharing, and Green Contexts provides finer-grained programmatic control within a single process.
By partitioning real-time requests and background batch tasks using Green Contexts, the response time of real-time requests can be made more stable and will not be slowed down by bursts of background task computation.
Using Green Contexts requires developers to have a clear understanding of the application's workload characteristics (which tasks are latency-sensitive, which are throughput-prioritized, and how much compute resource each requires); otherwise, resource partitioning is difficult to leverage effectively.
