Hello Philipp,

You can divide a Power5/5+ processor in tenths som the smallest partition 
will have 0.1 processor
A "whole" Power5/5+ processor is roughly 3000-3800CPW.
Some of the smaller i5 520 does not have one processor capacity - in your 
case just 0.32 processor.
According to your own formula that will give you the posibillity to create 
three partitions.
Makes sense?
