I'm currently running Ubuntu 14.04.2 Desktop.
The System Monitor tool is showing me 32 CPUs when I'm expecting 56. Should I be concerned?
Screenshot of System Monitor:
As you can see, it shows 32 CPUs.
Output of lscpu
:

As you can see, according to lscpu
, I should have 56 CPUs.
htop is also showing me 56 CPUs.
My machine is Dell's T7910 Precision tower. It has 2 Intel Xeon E5-2697 V3 processors, each having 14 cores and capable of 2 threads per core (as seen in the output of lscpu
, and further confirmed in BIOs).
I recall seeing 56 cores under System Monitor when I launched it in the "try ubuntu" mode from the installation disk before installing Ubuntu.
- Is there something wrong with my system configuration?
- If there is (e.g., hardware failure), what can I do to verify?
- Also, I noticed that my System Monitor does not have a "System" tab.
