Hi,
There are 128 cuda cores in Nano, Can I disable some cuda cores for power-saving? For example, I want only 96
or 64 cuda cores working.

Hi,

No. They are in the same GPU and cannot be partially turned off.

However, we do provide several system mode to help user trade off between power and performance.
