It shows double CPUs
[EMAIL PROTECTED] root]# grep -E '(processor|physical)' /proc/cpuinfo
processor : 0
physical id : 0
processor : 1
physical id : 3
[EMAIL PROTECTED] root]#
The count of physical id associated with processor tells how many core
it is. So in this case it is single core.
[EMAIL PROTECTED] root]# grep -E '(physical|processor)' /proc/cpuinfo
processor : 0
physical id : 0
processor : 1
physical id : 0
processor : 2
physical id : 3
processor : 3
physical id : 3
[EMAIL PROTECTED] root]#
In this case it is dual core with each CPU. Physically there are only
2CPUs and showing 4.
My question is:
If we can see double CPUs in both the case of HT & dual core, how do we
differentiate whether it is due to HT or dual core nature of CPU.
Cheers!
