cores/socket

Jump to solution

Hi experts

On one of my server i have below config

Processor1

Processor speed:2400 Mhz

Execution Technology: 10/10 cores, 20 threads

Memory Technology: 64bit capable

Internal L1 cache 320KB

Internal L2 cache 2560KB

Internal L3 cache 30720KB

In the same way i have another 3 Processors with same configuration.(Processor2,Processor3,Processor4)

I was asked below two questions plz guide me

Total Number of sockets per Node: 4 processors, 10 cores per processor so total number of sockets per node = 4*10=40 is this right answer?

Number of physical cores per Socket: ?

i have a question for myself, i see 20 threads, with hyperthreading how many cores will i get.

i am confused what is what

10 cores = 10 threads

10 cores with Hyperthreading enabled = 20 threads

From a physical point of view, you have 4 processors/sockets with 10 cores each, which makes 40 physical cores in total.

However, with Hyperthreading enabled, you get 80 logical cores.

So you have 4 Sockets and 10 cores per socket so logical processors would be 4*10 = 40

If hyperthreading is enabled then you would get double logical processors  = 80

Again how much your VMs see the processors depends on the hardware version of the VM and how much processors supported by VM depend upon operating system on VM.

For example windows server 2003 is limited to 4 CPUs.

Thanks alot,(i got it physical cores=40,logical cores=80)

but what is this 20 threads?
