DedicatedThreadPool

An instanced, dedicated thread pool for eliminating "noisy neighbor" problems on the CLR ThreadPool.

Installation

You can install DedicatedThreadPool via NuGet!

PS> Install-package Helios.DedicatedThreadPool

This package doesn't install any binaries, just the following C# file: Helios.Concurrency.DedicatedThreadPool.cs - which contains the DedicatedThreadPool, DedicatedThreadPoolTaskScheduler, and DedicatedThreadPoolSettings classes.

API

You can create a Helios.Concurrency.DedicatedThreadPool instance via the following API:

using (var threadPool = new Helios.Concurrency.DedicatedThreadPool(
        new DedicatedThreadPoolSettings(numThreads)))
{
    threadPool.QueueUserWorkItem(() => { ... }));
}

This creates a DedicatedThreadPool object which allocates a fixed number of threads, each with their own independent task queue.

This DedicatedThreadPool can also be used in combination with a DedicatedThreadPoolTaskScheduler for TPL support, like this:

//use 3 threads
var Pool = new DedicatedThreadPool(new DedicatedThreadPoolSettings(3));
var Scheduler = new DedicatedThreadPoolTaskScheduler(Pool);
var Factory = new TaskFactory(Scheduler);

 var task = Factory.StartNew(() =>
{
    //work that'll run on the dedicated thread pool...
});

task.Wait();

NOTE: DedicatedThreadPool is marked as internal by default, so it can be used opaquely across many dependent projects.
