Creating One Thread Per Processor

Environment.ProcessorCount Gets the number of logical processors on the current machine.

The CLR will then schedule each thread to a logical processor, this theoretically could mean each thread on a different logical processor, all threads on a single logical processor or some other combination.

using System;
using System.Threading;

class MainClass {
    static void Main() {
        for (int i = 0; i < Environment.ProcessorCount; i++) {
            var thread = new Thread(Secondary);
            thread.Start(i);
        }
        
    }

    static void Secondary(object threadNumber) {
        System.Console.WriteLine("Hello World from thread: " + threadNumber);
    }
}
