Partitioning GPU into MIG (Multi-Instance GPU)

1. Drain the node.

2. Run the command to convert ALL GPUs to MIGs:

sudo nvidia-smi -mig 1

3. Install nvidia-mig-parted on the node.

4. Install nvidia-mig-manager on the node. You can find the installation details here.

5. Create a config.yaml file for the node and place it in /etc/nvidia-mig-manager/config.yaml. Example:

version: v1
mig-configs:
  current:
  - devices: all
    mig-enabled: true
    mig-devices:
      1g.10gb: 7
  all-disabled:
  - devices: all
    mig-enabled: true
    mig-devices:
      1g.10gb: 7

You can also SSH into an existing MIG node and run sudo nvidia-mig-parted export.

6. Test persistence with reboots to ensure MIG settings are retained.

7. Don’t forget to uncordon the node.
