That is how HyperDispatch should work. Engines will be pseudo dedicated to
an LPAR. 3 LPARs on a W03 (or U03 of the orig question) with 3 logicals each
would tend to have one engine at 100% and the other two close to zero (if
all have equal demand) and weights of 33%.
on a z10BC U03 you probably won't see a 'measurable' difference. All the
