 Again two sockets, but this time with a more realistic 20-bit mask.
 
 Two real time tasks pid=1234 running on processor 0 and pid=5678 running on
 processor 1 on socket 0 on a 2-socket and dual core machine. To avoid noisy
 neighbors, each of the two real-time tasks exclusively occupies one quarter
 of L3 cache on socket 0.
+::
 
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
+  # mount -t resctrl resctrl /sys/fs/resctrl
+  # cd /sys/fs/resctrl
 
 First we reset the schemata for the default group so that the "upper"
 50% of the L3 cache on socket 0 and 50% of memory b/w cannot be used by
-ordinary tasks:

-# echo "L3:0=3ff;1=fffff\nMB:0=50;1=100" > schemata
+  # echo "L3:0=3ff;1=fffff\nMB:0=50;1=100" > schemata
 
 Next we make a resource group for our first real time task and give
 it access to the "top" 25% of the cache on socket 0.
+::
 
-# mkdir p0
-# echo "L3:0=f8000;1=fffff" > p0/schemata
+  # mkdir p0
+  # echo "L3:0=f8000;1=fffff" > p0/schemata
 
 Finally we move our first real time task into this resource group. We
 also use taskset(1) to ensure the task always runs on a dedicated CPU
 on socket 0. Most uses of resource groups will also constrain which
 processors tasks run on.
+::
 
-# echo 1234 > p0/tasks
-# taskset -cp 1 1234
+  # echo 1234 > p0/tasks
+  # taskset -cp 1 1234

 schemata would look like(Assume min_bandwidth 10 and bandwidth_gran is

+3) Example 3
 
 A single socket system which has real-time tasks running on core 4-7 and
 non real-time workload assigned to core 0-3. The real-time tasks share text
 and data, so a per task association is not required and due to interaction
 with the kernel it's desired that the kernel on these cores shares L3 with
 the tasks.

-# mount -t resctrl resctrl /sys/fs/resctrl

 Next we make a resource group for our real time cores and give it access
 to the "top" 50% of the cache on socket 0 and 50% of memory bandwidth on
 socket 0.

 Finally we move core 4-7 over to the new group and make sure that the
 kernel and the tasks running there get 50% of the cache. They should
 also get 50% of memory bandwidth assuming that the cores 4-7 are SMT
 siblings and only the real time threads are scheduled on the cores 4-7.

 Monitor the groups separately and also get per domain data. From the
 below its apparent that the tasks are mostly doing work on
