  • Red Hat ☛ Boost GPU efficiency in Kubernetes with NVIDIA Multi-Instance GPU

    Multi-Instance GPU (MIG) is a technology provided by NVIDIA to expand the performance and value of some of its GPU products. It can partition a GPU into multiple instances, with each instance fully isolated and having its own high-bandwidth memory, cache, and compute cores. This gives administrators the ability to support every workload, small or large, ensuring quality of service (QoS) while extending accelerated computing resources to all users."

    Kubernetes is an open source system for automating the deployment, scaling, and management of containerized applications. Kubernetes provides access to specialized hardware such as GPUs through its device plug-in framework. The NVIDIA GPU Operator uses the Kubernetes operator framework to automate the management of NVIDIA software components for GPU provisioning, including MIG.
