View source for MIG: Multi-Instance GPU

== Enabling MIG == 

MIG can be enabled on all GPUs or on a per GPU basis using the nvidia-smi tool.

To enable on all GPUs
<syntaxhighlight>
root@sdgx-server:~# nvidia-smi -mig 1
</syntaxhighlight>

Alternatively, MIG can be enabled on one GPU only

<syntaxhighlight>
root@sdgx-server:~# nvidia-smi -i 4 -mig 1
</syntaxhighlight>
