How to find the no of cpu, core and if its under HT technology CPU
Finding Physical Processors
$ grep ‘physical id’ /proc/cpuinfo | sort | uniq | wc -l
Finding Virtual Processors
$ grep ^processor /proc/cpuinfo | wc -l
Finding CPU cores
$ grep ‘cpu cores’ /proc/cpuinfo
“2″ indicates the two physical processors are dual-core, resulting in 4 virtual processors.
If “1″ was returned, the two physical processors are single-core.
If the processors are single-core, and the number of virtual processors is greater than the number of physical processors, the CPUs are using hyper-threading.
