## Project-HAMi: Heterogeneous AI Computing Virtualization Middleware
## Introduction
HAMi, formerly known as 'k8s-vGPU-scheduler', is a Heterogeneous device management middleware for Kubernetes. It can manage different types of heterogeneous devices (like GPU, NPU, etc.), share heterogeneous devices among pods, make better scheduling decisions based on topology of devices and scheduling policies.
It aims to remove the gap between different Heterogeneous devices, and provide a unified interface for users to manage with no changes to their applications. As of December 2024, HAMi has been widely used not only in Internet, public cloud and private cloud, but also broadly adopted in various vertical industries including finance, securities, energy, telecommunications, education, and manufacturing. More than 50 companies or institutions are not only end users but also active contributors.

HAMi is a sandbox and [landscape](https://landscape.cncf.io/?item=orchestration-management--scheduling-orchestration--hami) project of
[Cloud Native Computing Foundation](https://cncf.io/)(CNCF),
[CNAI Landscape project](https://landscape.cncf.io/?group=cnai&item=cnai--general-orchestration--hami).
## Device virtualization
HAMi provides device virtualization for several heterogeneous devices including GPU, by supporting device sharing and device resource isolation. For the list of devices supporting device virtualization, see [supported devices](#supported-devices)
### Device sharing
- Allows partial device allocation by specifying device core usage.
- Allows partial device allocation by specifying device memory.
- Imposes a hard limit on streaming multiprocessors.
- Requires zero changes to existing programs.

### Device Resources Isolation
A simple demonstration of device isolation:
A task with the following resources:
```
resources:
limits:
nvidia.com/gpu: 1 # requesting 1 vGPU
nvidia.com/gpumem: 3000 # Each vGPU contains 3000m device memory
```
will see 3G device memory inside container

## Architect
<img src="./imgs/hami-arch.png" width = "600" />
HAMi consists of several components, including a unified mutatingwebhook, a unified scheduler extender, different device-plugins and different in-container virtualization technics for each heterogeneous AI devices.
## Quick Start
### Choose your orchestrator
[![kube-scheduler](https://img.shields.io/badge/kube-scheduler-blue)](#prerequisites)
[![volcano-scheduler](https://img.shields.io/badge/volcano-scheduler-orange)](docs/how-to-use-volcano-vgpu.md)
### Prerequisites
The list of prerequisites for running the NVIDIA device plugin is described below:
- NVIDIA drivers >= 440
- nvidia-docker version > 2.0
- default runtime configured as nvidia for containerd/docker/cri-o container runtime
- Kubernetes version >= 1.16
- glibc >= 2.17 & glibc < 2.3.0
- kernel version >= 3.10
- helm > 3.0
### Install
First, Label your GPU nodes for scheduling with HAMi by adding the label "gpu=on". Without this label, the nodes cannot be managed by our scheduler.
```
kubectl label nodes {nodeid} gpu=on
```
Add our repo in helm
```
helm repo add hami-charts https://project-hami.github.io/HAMi/
```
Use the following command for deployment:
```
helm install hami hami-charts/hami -n kube-system
```
Customize your installation by adjusting the [configs](docs/config.md).
Verify your installation using the following command:
```
kubectl get pods -n kube-system
```
If both `vgpu-device-plugin` and `vgpu-scheduler` pods are in the *Running* state, your installation is successful. You can try examples [here](https://github.com/Project-HAMi/HAMi/blob/newprofile/examples/nvidia/default_use.yaml)
### WebUI
[HAMi-WebUI](https://github.com/Project-HAMi/HAMi-WebUI) is available after HAMi v2.4
For installation guide, click [here](https://github.com/Project-HAMi/HAMi-WebUI/blob/main/docs/installation/helm/index.md)
### Monitor
Monitoring is automatically enabled after installation. Obtain an overview of cluster information by visiting the following URL:
```
http://{scheduler ip}:{monitorPort}/metrics
```
The default monitorPort is 31993; other values can be set using `--set devicePlugin.service.httpPort` during installation.
Grafana dashboard [example](docs/dashboard.md)
> **Note** The status of a node won't be collected before you submit a task
## Notes
- If you don't request vGPUs when using the device plugin with NVIDIA images all the GPUs on the machine may be exposed inside your container
- Currently, A100 MIG can be supported in only "none" and "mixed" modes.
- Tasks with the "nodeName" field cannot be scheduled at the moment; please use "nodeSelector" instead.
## RoadMap, Governance & Contributing
The project is governed by a group of [Maintainers and Committers](https://github.com/Project-HAMi/HAMi/blob/master/AUTHORS). How they are selected and govern is outlined in our [Governance Document](https://github.com/Project-HAMi/community/blob/main/governance.md).
If you're interested in being a contributor and want to get involved in developing the HAMi code, please see [CONTRIBUTING](CONTRIBUTING.md) for details on submitting patches and the contribution workflow.
