Socket, core, threads, CPUs and lscpu
Hello
We have a server with this lscpu output [root@ids]# lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 64 On-line CPU(s) list: 0-63 Thread(s) per core: 2 Core(s) per socket: 16 Socket(s): 2 NUMA node(s): 2 Vendor ID: GenuineIntel CPU family: 6 Model: 85 Model name: Intel(R) Xeon(R) Gold 6130 CPU @ 2.10GHz I can see that we have 2 sockets each socket has 16 cores So I expected 32 CPUs, but we have 64. Are the threads are counted as CPUs ? Thanks |
Hardware threads are counted as execution units - sometimes called CPUs or cores. The devil is in the detail.
Do a search on SMT for the gory details. |
Thanks
