Impact of GPU Sharing#
NVIDIA vGPU software enables multiple virtual machines (VMs) to share a single physical GPU. This improves overall GPU utilization, but the way resources are shared depends on the underlying virtualization technology: either time-sliced vGPU or MIG-backed vGPU.
Time-Sliced vGPU Sharing#
With time-sliced vGPU, multiple VMs share GPU access over time. NVIDIA vGPU software uses the best effort scheduler by default, which aims to balance performance across vGPUs.
Scheduling Options for GPU Sharing#
To accommodate a variety of Quality of Service (QoS) levels for sharing a GPU, NVIDIA vGPU software provides multiple GPU scheduling options. For more information about these GPU scheduling options, refer to vGPU Schedulers.
MIG-Backed vGPU Sharing#
With MIG (Multi-Instance GPU), a single physical GPU is partitioned at the hardware level into multiple fully isolated GPU instances. This provides guaranteed performance isolation between VMs.
Performance Allocation#
Unlike time-sliced vGPU, MIG does not rely on time-sharing. Instead, each MIG-backed vGPU is assigned a dedicated slice of GPU resources with its own Streaming Multiprocessors (SMs) and memory subsystem. For example:
When four MIG instances are created, each instance delivers consistent and isolated performance to its assigned VM.
Within each MIG slice, up to 12 vGPUs can be created and time-sliced within that isolated slice. These vGPUs can be assigned to separate VMs, which continue to benefit from MIG’s hardware-level isolation boundaries.
