Hyper threading не работает на Ubuntu 16.04 [закрыто]
Я запускаю Ubuntu 16.04.4 LTS в качестве основной и единственной ОС на рабочем столе Intel Xeon E5-2666 v3, а процессор поддерживает гиперпоточность (HTT). Тем не менее, я вижу, что гиперпоточность отключена, когда я использую sudo dmidecode -t processor shows
