2 gamers 1 cpu with docker

[Elerek]

So last year Linus did this 

Is it possible to do the same thing on a single install of windows with Docker and https://github.com/NVIDIA/nvidia-docker?

[Electronics Wizardy]

No, because Docker doesn't support a gui

 

More on this

 

This ins't gpu passthrough, this is passing through the cuda calls(not the same as a opengl/directx call).

 

Also you limited to running the same os as the host, so linux.

 

Just use a vm using something like Xen, ESXI, Kvm, or virtualbox on linux.

 

Hyper-v(virtualbox and ESXI also have a simmilar solution but its bad) has a vgpu thing so you can have mutiple users on one gpu.

 

If you want a good solution for multiple users on one gpu, you need nvidia tesla's or grid and use their vgpu on citrix xen or esxi.

AMD also has a line of server GPU's designed specifically for ESXi that uses SR-IOV to share a single GPU between multiple VMs. In some ways it's better than Nvidia's solution but of course it depends on your specific application/use case.

So what about this then? https://www.google.com/url?sa=t&source=web&rct=j&url=https://github.com/thewtex/docker-opengl-nvidia&ved=0ahUKEwjovdWgjO7OAhXB3SYKHQOQCJAQFggbMAA&usg=AFQjCNExVIZcDqHVvSOG1s7laXdN3XV29Q&sig2=rBO8gu1tqH1fTYzkKIiCnA

 

I'm not trying to have multiple people in one gpu, I'm trying to get a docker image to output video on one of two gpus and possibly get a dual headed system without needing to buy two copies of Windows.

Worth a shot, remember take note of the warning in the repo and don't expect good performance, shouldn't be a big issue unless you want to play games from within the docker container.

 

Remember what you are trying to do from a technical standpoint is share a GPU between more than one OS so the fundamental issues still apply between what you are wanting to do and having more than 1 VM using the same GPU.

 

Nvidia's core focus on your original linked git repo is to allow docker containers to use Nvidia server GPUs to do compute tasks and not to output any graphical information.

Okay, I might try it at some point. For now I'm building a vm based system like Linus did with an old server I got for cheap. So far so good there. Maybe in a year or so when docker for windows has gotten better I'll try a docker route. I'm not expecting anything amazing yet, I just really want it to be possible  In the long run if it is possible to get a gpu and usb devices passed through to a docker and properly isolate them, it could be a more viable means of a multi-headed gaming rig than vms. Not only could you possibly have better performance with less OS overhead, but you could do it on just a single windows license instead of needing 1 for every vm. At least that was my thinking.

Windows Server 2016 is releasing during Microsoft Ignite, September 25~, which has many improvements and includes Hyper-V containers. My work has been part of the early access/RDP/TAP program and I can definitely say Server 2016 has tons of really useful stuff coming, check it out when you can.

I don't think it would work at all though. This is only for cuda, no opengl/directx. This would also work with linux if im right(i don't know about docker on windows).

 

You also can't run a X screen from a docker container, so it doesn't matter how much gpu power you have.

You're wrong on both of those. That last link is explicitly for enabling opengl in the docker and there are multiple forums where people have talked about ways to get docker to successfully run programs with an x server.
