Which technology partitions a single GPU into isolated instances for parallel workloads?

MIG, or Multi-Instance GPU, is the NVIDIA technology that partitions one supported GPU into multiple isolated GPU instances. NVIDIA’s MIG User Guide states: “The Multi-Instance GPU (MIG) User Guide explains how to partition supported NVIDIA GPUs into multiple isolated instances, each with dedicated compute and memory resources.” It also explains that MIG enables efficient GPU utilization across multiple users or workloads with guaranteed performance.

NVIDIA AI Enterprise documentation also defines MIG as hardware-level GPU partitioning into isolated instances, each with dedicated resources. Therefore, the correct answer is MIG.

Why the other options are incorrect: vGPU virtualizes GPU access for virtual machines, but the specific technology for partitioning a single physical GPU into isolated GPU instances is MIG. NVLink is a high-speed GPU interconnect. NCCL is a communication library for multi-GPU and multi-node collective communication.
