NAME
     misercpuset - cpuset configuration files

DESCRIPTION
     A cpuset is defined by a cpuset configuration file and a name.  The
     cpuset configuration file is used to list the CPUs that are members of
     the cpuset and contains any additional parameters needed to define the
     cpuset.  The file permissions of the configuration file define access to
     the cpuset. Everytime permissions need to be checked, the current
     permissions of the file are used. It is therefore possible to change
     access to a particular cpuset, without having to tear it down and
     recreate it, simply by changing the access permissions. Read access
     allows a user to retrieve information about a cpuset while execute
     permission allows the user to attach a process to the cpuset.

     The name of the cpuset is a three to eight character string.  Queue names
     having one or two characters are reserved for use by IRIX.

EXAMPLE
     The following configuration file describes an exclusive cpuset containing
     3 CPUs:

     #cpuset configuration file
     EXCLUSIVE

     CPU 1
     CPU 5
     CPU 10


     This specification will create a cpuset containing 3 CPUs, and will
     restrict those cpus to running threads that have been explicitly assigned
     to the cpuset.

SUMMARY
     Commands are newline terminated, characters following the comment
     delimiter '#' are ignored, case matters, and tokens are separated by
     whitespace which is ignored.

     The valid tokens are:

     EXCLUSIVE
          Defines a cpuset to be restricted. It can occur anywhere in the
          file. Anything else on the line is ignored.

     CPU cpuid
          Specifies a CPU that will be part of the cpuset.
