[Gate-users] Gate on GPU

HI all,

I see that some of you have tried to install GAte with GPU support and I
have some questions:

First of all,  does gate support Radiotherapy simulations on the GPU?
I found this actor GateGPUPhotRadTheraActor but didn't find any examples;
could I simply replace my current actor with "/gate/actor/addActor
GateGPUPhotRadTheraActor   " ?

Secondly, is there expected to be a speed up when using GateGPU compared to
when using GateCPU ? Specifically, for a small local cluster of 40 cores
(5 nodes Xeon(R) CPUs , E5420  @ 2.50GHz, with 8 cores each) compared to
using GPU enabled gate ( GeForce GTX 1080) on one node ?

Appreciate any opinions as I embark on this journey.
