Usage of CKRM without a classification engine
-----------------------------------------------

1. Create a class

   # mkdir /rcfs/taskclass/c1
   creates a taskclass named c1 , while
   # mkdir /rcfs/socket_class/s1
   creates a socketclass named s1 

The newly created class directory is automatically populated by magic files
shares, stats, members, target and config.

2. View default shares 

   # cat /rcfs/taskclass/c1/shares

   "guarantee=-2,limit=-2,total_guarantee=100,max_limit=100" is the default
   value set for resources that have controllers registered with CKRM.

3. change shares of a <class>

   One or more of the following fields can/must be specified
       res=<res_name> #mandatory
       guarantee=<number>
       limit=<number>
       total_guarantee=<number>
       max_limit=<number>
   e.g.
	# echo "res=numtasks,limit=20" > /rcfs/taskclass/c1

   If any of these parameters are not specified, the current value will be
   retained. 

4. Reclassify a task (listening socket)

   write the pid of the process to the destination class' target file
   # echo 1004 > /rcfs/taskclass/c1/target	

   write the "<ipaddress>\<port>" string to the destination class' target file 
   # echo "0.0.0.0\32770"  > /rcfs/taskclass/c1/target

5. Get a list of tasks (sockets) assigned to a taskclass (socketclass)

   # cat /rcfs/taskclass/c1/members
   lists pids of tasks belonging to c1

   # cat /rcfs/socket_class/s1/members
   lists the ipaddress\port of all listening sockets in s1 

6. Get the statictics of different resources of a class

   # cat /rcfs/tasksclass/c1/stats
   shows c1's statistics for each resource with a registered resource
   controller.

   # cat /rcfs/socket_class/s1/stats
   show's s1's stats for the listenaq controller.	

7. View the configuration values of the resources associated with a class

   # cat /rcfs/taskclass/c1/config
   shows per-controller config values for c1.

8. Change the configuration values of resources associated with a class
   Configuration values are different for different resources. the comman
   field "res=<resname>" must always be specified.

   # echo "res=numtasks,parameter=value" > /rcfs/taskclass/c1/config
   to change (without any effect), the value associated with <parameter>.
