[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!
