Driver and workers

Is the driver becomes worker after the execution of the script ?
For example, if i have one machine with 4 GPUs, and i choose 4 workers (1 per GPU). Driver will use some CPU or it becomes a worker and use 1 GPU ?

the driver does not take up resources even while the job is running, so typically the driver shouldn’t be doing anything too intense.

Hi @Alex
Thank you for your answer !
