as all know lscpu give the info about number of CORE and number of Thread

Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit
Byte Order:            Little Endian
CPU(s):                48
On-line CPU(s) list:   0-47
Thread(s) per core:    2

I am searching about command that can give the total as

( number of CORE ) X ( number of Thread ) = 96

so output will be as case above = 96 CPU

we can do as

 CORE=` nproc --all `
 THREAD=`  lscpu | grep -i Thread | awk '{print $NF}' `


echo "$(( $CORE*$THREAD ))"

but this isn't elegant way

or maybe other elegant approach ?

we try also this ( but not get the total 96 cores's )

# echo $num_cpus
  • Does your lscpu output not give a Core(s) per socket and Socket(s) line? – Stéphane Chazelas Aug 13 at 7:00
  • The CPU(s) line reports the number of "logical" CPUs, so number of threads. I'd expect your system has 24 cores, probably 2 sockets of 12 cores each. – Stéphane Chazelas Aug 13 at 7:05

Both nproc and the CPU(s) row in lscpu are the total number of threads.

So all you need to get the total number of threads is:

  • nproc give only 48 and not 96!! so this isn't answer that I accepted – yael Aug 13 at 4:56
  • @yael, on my system, nproc also reports the number of threads. I would expect your system has 24 cores, 48 threads. Probably 2 x 12 core CPUs. – Stéphane Chazelas Aug 13 at 7:02
  • you can see from my question - CPU = 48 and Thread = 2 , so its 96 – yael Aug 13 at 9:27
