  <title>What is Solaris mode?</title>

    <p>Very brief topic. Explain what "Solaris mode" in the preferences dialog
 means. The current manual has some information.</p>
  </comment>

  <p>In a system that has multiple CPUs or <link xref="cpu-multicore">cores</link>,
 processes can use more than one at the same time. It is possible for the
 <gui>% CPU</gui> column to display values that total greater than 100% (i.e.
 400% in a 4-CPU system). <gui>Solaris mode</gui> divides the <gui>% CPU</gui>
 for each process by the number of CPUs in the system so that the total will be
 100%.</p>

  <p>To display the <gui>% CPU</gui> in <gui>Solaris mode</gui>:</p>

  <steps>
    <item><p>Click <gui>Preferences</gui> in the app menu.</p></item>
    <item><p>Click the <gui>Processes</gui> tab.</p></item>
    <item><p>Select <gui>Divide CPU Usage by CPU Count</gui>.</p></item>
  </steps>

    <note><p>The term <gui>Solaris mode</gui> derives from Sun's UNIX, compared
 to the Linux default of IRIX mode, named for SGI's UNIX.</p></note>
