I have below configuration of a unix machine:

Command :

lscpu | grep -E '^Thread|^Core|^Socket|^CPU\('

Result : 

CPUs :               8
Thread(s) per core : 8
Core(s) per socket : 1
Socket(s)          : 1

My understanding is:

Max. number of threads that can run on this machine = Sockets X Cores per Socket X Thread(s) per Core

Or

Max. number of threads that can run on this machine = CPUs

Is this understanding correct?

or

Is there different formulae to decide maximum number of threads that can run on a machine?

EDIT

I meant max. number of threads that can run in parallel.

e.g. by starting n number of threadpools etc.

For increasing performance of my application I want to run it on max. number of threads, can it be determined by above parameters?

  • Check: https://stackoverflow.com/questions/344203/maximum-number-of-threads-per-process-in-linux and https://stackoverflow.com/questions/9361816/maximum-number-of-processes-in-linux. Also by *running* do you mean *running in parallel*? Or the maximum that can be present? – Allan May 22 '19 at 08:38
  • @Allan yes I mean running in parallel, So parameters which I have mentioned have any relation in deciding max. number of threads than can run in parallel. – Raj May 22 '19 at 08:41
