Hi,
I am trying to enable 'hyperthreading' on rhel5 86_64 bit servers.
- kernel 2.6.18-194.8.1.el5xen
- The ht is enabled in bios,
- [root@server ~]# dmesg |grep -i ht
Brought up 8 CPUs
Installing knfsd (copyright (C) 1996

- cat /proc/cpuinfo |grep -i "ht" is showing the output of ht
- Checked the /proc/cpuinfo
processors : 8
siblings : 1
cpu cores : 1
- when I am executing top , getting 8 cpus running.
In a document it was mentioned, if siblings and cpu cores are same then
hyperthreading is not enabled. So for my case I will say that it is not enabled.
For rhel 5 onwareds there is no smp kernel found.
So how I will confirm for hyperthreading enabled.
Thanks in advance
