[Cin] HW in render farm

Hi all I am using several headless machines (cin -d 1200) as a render farm. Question : If the master node is using an accelaration (HW) do the slave nodes automatically use the said acceleration ? if no but is a matter of local configuration for a slave where can I set it up ? Now, to make it more complex : if the master is running on vdpau (or CUDA) can a slave run on vaapi ? Thanks in advance Ed
