title: What is socket, core, threads, CPU?
body: <p>I am currently volunteering to learn about linux servers and also I am interested in learning about cluster computing techniques.</p>
  
  <p>In this lab, they have a small cluster with one head node and two compute nodes. </p>
  
  <p><a href="https://i.stack.imgur.com/cRQFz.png" rel="noreferrer">When I tried the lscpu command on head node, compute node1,node2. Click the link to view the details.</a></p>
  
  <p>CPUs              - 24 in head, computenode1 and computenode2. <strong>Is it referring to 24 physical CPUs in the motherboard?</strong></p>
  
  <p>Sockets           - 2 in head, computenode1 and computenode2.<strong>Can anyone explain it?</strong></p>
  
  <p>Cores per socket  - 6 in head, computenode1 and computenode2.<strong>Can anyone explain it?</strong></p>
  
  <p>Threads per core  - 2 in head, computenode1 and computenode2.<strong>Can anyone explain it?</strong></p>
