To display the Share Tree Policy Parameters, click the arrow at the right of the Node Attributes.

• CPU [%] slider — This slider's setting indicates what percentage of Combined Usage CPU is. When you change this slider, the MEM and I/O sliders change to compensate for the change in CPU percentage.

• MEM [%] slider — This slider's setting indicates what percentage of Combined Usage memory is. When you change this slider, the CPU and I/O sliders change to compensate for the change in MEM percentage.

• I/O [%] slider — This slider's setting indicates what percentage of Combined Usage I/O is. When you change this slider, the CPU and MEM sliders change to compensate for the change in I/O percentage.

  Note –

  CPU [%], MEM [%], and I/O [%] always add up to 100%

• Lock Symbol — When a lock is open, the slider that it guards can change freely. The slider can change either because the slider was moved or because it is compensating for another slider's being moved.

  When a lock is closed, the slider that it guards cannot change. If two locks are closed and one lock is open, no sliders can be changed.

• Half-life — Use this field to specify the half-life for usage. Usage is decayed during each scheduling interval so that any particular contribution to accumulated usage has half the value after a duration of half-life.

• Days/Hours selection menu — Select whether half-life is to be measured in days or hours.

• Compensation Factor — This field accepts a positive integer for the compensation factor. Reasonable values are in the range between 2 and 10.

  The actual usage of a user or project can be far below its targeted usage. The compensation factor prevents such users or projects from dominating resources when they first get those resources. See Compensation Factor for more information.
