Qarnot computing C# SDK

QarnotSDK is a C# assembly designed to interact with Qarnot cloud computing service. It allows users to launch, manage and monitor payloads running on distributed computing nodes deployed in Qarnot’s digital heaters. You can find samples and detailed information on http://computing.qarnot.com.

Getting Started

Get your Qarnot account

Create your Qarnot account at http://account.qarnot.com and get your qarnot connection token.

Add the SDK to your project

You can find the sdk package in nuget : https://www.nuget.org/packages/QarnotSDK

And install it with the dotnet add package QarnotSDK command.

Run a new project

Create a new Connection object using your Qarnot token: new QarnotSDK.Connection("QARNOT_TOKEN_HERE") Create a new QTask object and submit it.

Projects Examples

Hello example

All the Qarnot tasks run inside docker containers (linux or windows envs).

A basic task will need a name, a profile (it define the task specificities), and a number of instance to be launch. The generic profile is docker-batch. This profile will launch a ubuntu docker image that need a shell command to execute.

using System;
using QarnotSDK;
using System.Threading;
using System.Threading.Tasks;

namespace HelloWorldQarnot
{
    class Program
    {

        static async Task Main(string[] args)
        {
            var myQarnotToken = "secret_token"; // Retrieve your token from https://account.qarnot.com
            var connection = new QarnotSDK.Connection(myQarnotToken);
            var task = connection.CreateTask("HelloWorldTask", "docker-batch", 4);
            task.Constants.Add("DOCKER_CMD", "echo hello world from node ${INSTANCE_ID}!"); // The docker command to be launch
            await task.RunAsync();
            Console.WriteLine(await task.StdoutAsync());

            Console.WriteLine("End of the run!");
        }
    }
}

Output :

" 0> Hello : 0"
" 2> Hello : 2"
" 3> Hello : 3"
" 1> Hello : 1"
End of the run!
