Gpu sharing

Currently, the standard Kubernetes version does not support to share GPUs across pods. However, by extending the kubernetes scheduler module we confirmed that it is possible to actually virtualise the GPU Memory and therefore unlock flexibility in sharing and utilising the available GPU power.

In this blog post, we aim to guide you through the set-up steps to share Nvidia GPUs on top of Kubernetes, a container-orchestration platform. For example, in the context of Machine Learning, during training you might utilise the full GPU capacity with one training job, but during inference you will most likely want to spread multiple instances across the available GPU s.

Sharing a GPU within a virtual machine or on bare metal is also feasible but not sufficient if we want to unlock the GPU capacity in a container-orchestration framework. We assume that you start from a kubernetes cluster with control plane access.

In a follow-up post we will provide sample code to deploy a self-managed kubernetes cluster on Google Cloud. You might wonder why GPU sharing is important, because we can spin up a wide range of GPUs on-demand on multiple cloud providers nowadays. The problem is more visible and profound in an on-premise setting. If we deploy Kubernetes on top of these machines, we have basically virtualised the compute and memory capacity of these machines into a cluster. But as you can see from the docs as mentioned in the introduction :.

The consequence is that a single container claims the entire GPU. This is especially worrisome when your workload only utilises a small fraction of your GPU power. The Graphics Processing Unit can theoretically be separated in the hardware layer. In this case the separation is done at the physical level and the workload is isolated to the available separated hardware chunk. Not many GPUs support this advanced hardware layer separation.

It is probably a costly feature that will only ship with very large GPUs. Another way of separating and sharing the GPU, is on the software layer. In this case the separation is done at the software level and the workload can reach the entire GPU capacity. The software layer should handle the isolation of workloads, meaning that you should limit the machine power somewhere in your code.I've gotten a thrust into the gpu in a server world about a month ago and i'm finding it hard to believe that MS best answer to vmware and citrix is DDA.

What is in the works? I can see how dda is a step forward from remote fx allowing the os to have direct access to the hardware, However there should still be a way to have a layer between that allows the hardware to be utilized on what ever vm needs it. Is there an update to hyper-v on the way? Attachments: Up to 10 attachments including images can be used with a maximum of 3. I want to say that your current discovery is correct, Microsoft on how to do this is just using DDA.

We need to be aware of is the fact that not every Hyper-V virtual machine can take advantage of GPU acceleration. Obviously, guest operating system support is required, but there is more to it than that. When you create a virtual machine in Hyper-V, you are asked whether you would like to create a Generation 1 virtual machine or a Generation 2 virtual machine. The option exists only for Generation 1 virtual machines.

Many large users including cloud giants such as Google, take the open source KVM and roll their own version. There is a large open source KVM user base who are quite happy to self-support, including a large academic research community. Open-sourced drivers enable both vendors and others to innovate and develop specialist enhancements. KVM is also a very popular choice in the cloud OpenStack ecosystem. Shared GPU reduces the cost of providing graphics and suits the economies of scale and cost demanded in Cloud well.

I imagine for the commercial and cloud based KVM hypervisors, ready access to drivers can only help accelerate and smooth their development on top of KVM. Currently there are only guest drivers for Windows OSs. However being open source, this opens up the possibility for a whole host of third-parties to develop variants for other platforms. There is also an AMD community forum where you can ask more questions if this is a technology of interest to you and read the various stacks and applications other users are interested in.
