Linux cервер не видит потоки процессора?

На Linux сервере установлено 4 CPU Xeon, проверяя через lscpu понятно что все 4 процессора он видит, однако, используя htop заметно, что всего 4 потока (скорее всего по 1 потоку от каждого процессора), хотя процессоры 16 ядерные, 32 потока и суммарно должно быть 128 потоков.
