Distributed rendering with GPU

[christophd.]

Hi vlado,
is it possible to use a second machine as renderslave for gpu-rendering??
I tried that but I think the slave just uses his cpu instead of gpu.
Do I need an extra license?
regards,

Nop u dont need extra license. Just install lastes drivers, set up Select OpenCL devices for V-Ray RT GPU to use ur graphic card and use Vray RT distributed bucked rendering + GPU kerner.


The only reason that I know of when ur slave will use CPU is when GPU will ''fail'' (not enought memory or driver maybe ? ) and sillently will use cpu.

Good luck.

Hi Dadal,
thanks for your help....i have latest drivers installed, opencl is selected...my active shade window says that opencl is in use but it is about 10 times slower than my workstation (same cpu, same gpu)....

okay, so thats over DBR or just on node?

Lets get it straight... Workstation works fine, and the node slow and / or not in dbr right ?

latest drivers but NOT beta one right?

...workstation works fine...no beta drivers...render slave (identical configuration as workstation) is very slow...

Try running the render server manually rather than as service, and see if it helps.

Also try doing a simple render on slave too. Maybe it need to do one standard render 1st time to get it working. The last build need some long time to build opencl 1st time us start it.
