Detect-GPU

简体中文

Overview

Detect-GPU is an HTTP server that calls go-nvml and provides an api to get information about the NVIDIA GPU on a Linux server.

Because we may use macOS or Windows for development, but go-nvml needs Linux NVIDIA driver, so it will report error during development.

And we split it out as a standalone HTTP service so that we can compile and run the main application successfully even in an environment without NVIDIA drivers.

Build from source

$ git clone https://github.com/mayooot/detect-gpu
$ cd detect-gpu
$ make linux

Test

$ make test

Installation

Detect-GPU is available using the standard go get command.

Install by running:

$ go get github.com/mayooot/detect-gpu/pkg/detect 

Usage

You can refer to the example for usage.

Like this:

package main

import (
	"fmt"
	"time"

	"github.com/mayooot/detect-gpu/pkg/detect"
)

func main() {
	timeOutDuration := 500 * time.Millisecond

	testClient := detect.NewClient(detect.WithTimeout(timeOutDuration))
	if err := testClient.Init(); err != nil {
		panic(err)
	}
	defer testClient.Close()

	gpus, err := testClient.DetectGpu()
	if err != nil {
		panic(err)
	}
	for _, gpu := range gpus {
		fmt.Printf("%#+v\n", gpu)
	}
}
