  Return the number of CPUs.

  CLI Example:

      salt '*' ps.num_cpus

salt.modules.ps.pgrep(pattern, user=None, full=False, pattern_is_regex=False)

  Return the pids for processes matching a pattern.

  If full is true, the full command line is searched for a match, otherwise only the name of the command is searched.

      salt '*' ps.pgrep pattern [user=username] [full=(true|false)]

  pattern

    Pattern to search for in the process list.

  user

    Limit matches to the given username. Default: All users.

  full

    A boolean value indicating whether only the name of the command or the full command line should be matched against the pattern.

  pattern_is_regex
