I'll take a shot at bits of this: > 1) What are the signs of a CPU being preempted and given to another LPAR? Look at the logical cpu (PR, first column) in the system trace table and the physical cp (CP, last column). When they change (assuming more than one lp and more than one cp), it means the unit of work ended up on another logical/physical lpar. Look at CLKC, EXT entries.
> 3) Does the preempted piece of work have to wait for that CPU to come back or > can it be dispatched on another CPU in the LPAR? Following and CLKC and an EXT entry, you should see a DSP entry with the same psw address. It can come back both on another logical cp and/or on another physical cp.
