      The one I run my simulations on, has 115,984 CPUS (processors or computing chips) in it, compared to maybe 2-4 in a home PC.
      It has 169,000 GB of memory compared to a home computer which might have 8.
      It uses about 2,400,000 W of electricty, compared to 300 on your home computer!
      So its big!

      I just use a normal computer in my office, but I need lots of data storage because the images we get from big telescopes are sometimes pretty huge 😀
