  <p>
    The gem5 simulator is a modular platform for computer-system architecture research, encompassing system-level architecture as well as processor microarchitecture.
    gem5 is a <i>community led</i> project with an <a href=/governance/>open governance</a> model.
  </p>
  <p>
    gem5 was originally conceived for computer architecture research in academia, but it has grown to be used in computer system design by academia, industry for research, and in teaching.
