Figure 13 Toggle the Capped/Uncapped option
You have to consider the number of virtual processors to be able to use all the
CPUs from the shared processor pool.
In our example, after the CoD operation, we have 3.0 available processing units
in the shared processor pool and 1 dedicated processor allocated to node oli.
The partition nicole_vio uses 0.8 processing units and is capped.
Partition julia uses 0.2 units and 1 virtual processor, and can use 1 physical CPU.
Adding 1 virtual CPU allows this partition to use a maximum of 2.0 processing
units.
In Example 10, we produced heavy CPU load on partition julia while the other
partition using the shared processor pool is in an idle state. The
shows the actual number of physical processing units used by partition julia.
