Effects of processing weights

Several implications are derived from the rules described above. First, every time a sharing LP is activated or deactivated, the share of all other active LPs, using the same processor types, changes. This happens because the total of the processing weights has changed.

Because the processing share of LPs can vary, the actual utilization reported by monitors such as RMF can be different from the weights. In systems at less than 100% utilization, some LPs could receive greater than their share if other LPs are not using their share. The number of CPs defined also affects the maximum resource allocated to that LP. For example, an LP defined to have two CPs on a three-way CPC can never be allocated more than 67% of the CP resources no matter what its processing weight.
