GPU Sharing Scheduler Extender in Kuberntes

Overview

More and more data scientists run their Nvidia GPU based inference tasks on Kubernetes. Some of these tasks can be run on the same Nvidia GPU device to increase GPU utilization. So one important challenge is how to share GPUs between the pods. The community is also very insterested in this topic.

Now there is a GPU sharing solution on native Kubernetes you can take. it is based on scheduler extenders and device plugin mechanism, so you can reuse this solution easiliy in your own Kubernetes.

Prerequisites

• Kubernetes 1.11+
• golang 1.10+
• NVIDIA drivers ~= 361.93
• Nvidia-docker version > 2.0 (see how to install and it's prerequisites)
• Docker configured with nvidia as the default runtime.

Developing

Scheduler Extender

# git clone https://github.com/AliyunContainerService/gpushare-scheduler-extender.git && cd gpushare-scheduler-extender
# docker build -t cheyang/gpushare-scheduler-extender .

Device Plugin

# git clone https://github.com/AliyunContainerService/gpushare-device-plugin.git && cd gpushare-device-plugin
# docker build -t cheyang/gpushare-device-plugin .

Kubectl Extension

• golang > 1.10

# mkdir -p $GOPATH/src/github.com/AliyunContainerService
# cd $GOPATH/src/github.com/AliyunContainerService
# git clone https://github.com/AliyunContainerService/gpushare-scheduler-extender.git
# cd gpushare-scheduler-extender
# go build -o $GOPATH/bin/kubectl-inspect-gpushare-v2 cmd/inspect/*.go

Demo

- Demo 1: Deploy multiple GPU Shared Pods, and they are scheduled to the same GPU device in binpack way

- Demo 2: Avoid GPU Memory requests can fit the node level, but not for the GPU device level
