What is MIG?

MIG (Multi-Instance GPU) is a feature available on certain NVIDIA GPUs (like those based on the Ampere and later architectures). It allows a single physical GPU to be partitioned into multiple, isolated GPU instances. Each instance has its own dedicated memory, compute resources, and I/O paths. This is commonly used in environments requiring strong isolation, Quality of Service (QoS), and predictable performance, such as virtualized environments, containerized applications, and high-performance computing workloads.
