vDGA GRID K2 passthrough multi-gpu support
Hi, I have 3 x Dell R730s configured with 2 x NVIDIA GRID K2 boards in each servers. I have dedicated 1 GPU to a VM by activating the passthrough mode on one of my ESXi server. When launching an application Image Generator (Genesis IG), I have noticed that my GPU was actually being used at 99% which explains some not so good performance, it is close to what the GeForce 970GTX on a regular pc provides but not really there yet. In order to address the performance issue I have decided to add another GPU to this machine in passthough mode and I have now 2 GRID GPUS installed and showing up on my VM. My question is it possible to have the 2 GPUS working together in a multi-gpu support concept or SLI? Right now if I launch the same application I can only see 1 GPU working and the other one is at 0%. A single GPU would probably be enough to run the IG if I didnt have to waste 25% on the GPU for the PCoIP session alone going to my Zero client. Thanks Pascal

That is really unfortunate. Thanks for your prompt reply. Pascal

what is the performance difference of a GRID 2.0 M60 board compared to the K2s ?

Depending on the workload between 1.4x and 2x It also has double the amount of GPU RAM.
