Carbon Aware Computing Hangfire Extension
Overview
A Hangfire extension to schedule tasks with carbon awareness in mind. The best point in time is calculated based on emission forecasts to get a window with a minimal grid carbon intensity.
Installation
CarbonAwareComputing.Hangfire is available as a NuGet package. You can install it using the NuGet Package Console window:
Install-Package CarbonAwareComputing.Hangfire
After installation add the extension to the Hangfire configuration.
builder.Services.AddHangfireCarbonAwareExecution(configuration => configuration
.UseCarbonAwareExecution(new CarbonAwareDataProviderOpenData(), ComputingLocations.Germany)
);
Usage
There are extension to Enqueue and Schedule with WithCarbonAwarenessAsync.
Fire and Forget tasks
Setup the latest execution time and the estimated task duration. The extension will do a best effort to get a window with the estimated task duration and minimal grid carbon intensity. When no window can be detected, the task is enqueued immediately.
//use the extension methods
IBackgroundJobClient client = GetBackgroundJobClient();
await client.EnqueueWithCarbonAwarenessAsync(
() => Console.WriteLine("Enqueue carbon aware jobs"),
DateTimeOffset.Now + TimeSpan.FromHours(2),
TimeSpan.FromMinutes(5));
//or use the static versions
await CarbonAwareBackgroundJob.EnqueueAsync(
() => Console.WriteLine("Enqueue carbon aware jobs"),
DateTimeOffset.Now + TimeSpan.FromHours(2),
TimeSpan.FromMinutes(5));
Delayed tasks
Setup the earliest and latest execution time and the estimated task duration. The extension will do a best effort to get a window with the estimated task duration and minimal grid carbon intensity. When no window can be detected, the task is scheduled as desired.
//use the extension methods
IBackgroundJobClient client = GetBackgroundJobClient();
await client.ScheduleWithCarbonAwarenessAsync(
() => Console.WriteLine("Schedule carbon aware jobs"),
DateTimeOffset.Now + TimeSpan.FromHours(2),
TimeSpan.FromMinutes(20),
TimeSpan.FromMinutes(30), TimeSpan.FromMinutes(5));
//or use the static versions
await CarbonAwareBackgroundJob.ScheduleAsync(
() => Console.WriteLine("Schedule carbon aware jobs"),
DateTimeOffset.Now + TimeSpan.FromHours(2),
TimeSpan.FromMinutes(20),
TimeSpan.FromMinutes(30), TimeSpan.FromMinutes(5));
Recurring tasks
Setup the maximum execution delay after planned schedule time and the estimated task duration. The extension will do a best effort to get a window with the estimated task duration and minimal grid carbon intensity. When no window can be detected, the task is scheduled as desired.
//use the extension methods
IRecurringJobManager manager = GetRecurringJobManager();
manager.AddOrUpdateCarbonAware(
"daily",
() => Console.WriteLine("Hello, world!"),
Cron.Daily,
TimeSpan.FromHours(2),
TimeSpan.FromMinutes(20));
//or use the static versions
CarbonAwareRecurringJob.AddOrUpdate(
"daily",
() => Console.WriteLine("Hello, world!"),
Cron.Daily, TimeSpan.FromHours(2),
TimeSpan.FromMinutes(20));
The Hangfire Carbon Aware Extension will prevent the execution of the current instance of the recurring job. It is calculation a execution window with minimal carbon impact and the schedule that task. In the dashboard you will see the notice that the job was executed and a newly planned task.
Fallback
If your computing location is outside Europe or you need other forecasts the WattTime data provider may be useful. You need a valid WattTime account to use the data provider.
builder.Services.AddHangfireCarbonAwareExecution(configuration => configuration
.UseCarbonAwareExecution(
() => new CarbonAwareExecutionOptions(
new CarbonAwareDataProviderWattTime(userName, password),
ComputingLocations.Germany))
);
Extensibility
For custom forecasts or scenarios you don't want the build in provider add a own data provider. You may extend the abstract base class CarbonAwareDataProvider or use the CarbonAwareDataProviderWithCustomForecast.
Methodology
Hangfire.CarbonAwareExecution Extension make use of the Carbon Aware SDK a Green Software Foundation Project. There are some extensions to the SDK to use cached offline data sources in our fork.
The emission forecast data are uploaded periodically to a Azure Blob Storage for a given grid region and are public (e.g. for Germany https://carbonawarecomputing.blob.core.windows.net/forecasts/de.json).
For every grid region a data provider is needed:
- Germany: The API from https://www.energy-charts.info/ are used. The data is the share of renewable energy to the total power production. The origin data source is from entso-e. The data is generated every day at 19:00+02 for the next day. After 19:00+02 the maximum forecast is next day 24:00+02.
Other data sources and regions are added soon.
