На самом деле .NET Framework и Windows довольно хорошо управляют потоками, равномерно распределяя их по каждому процессору. Однако распределением потоков можно манипулировать вручную, используя Process и ProcessThread.

Теперь проверьте диспетчер задач, мы видим, что второй процессор принимает на себя все рабочие нагрузки. Окно диспетчера задач
