What happens to those "processor units", then ?
They sit there, running idle. The System does have 1.00 processors. However, without the accelerator feature, you can only assign work to 0.32 processors - thus you don't get the full performance of the system. This is also the reason why the smaller systems are limited to two or three LPARs, because you will need a minimum of 0.10 Processor for each LPAR. The remaining 0.78 processors sit there, unassigned, handling something similar to the x86 NOP/HLT instructions. I think it is a real shame that IBM does this, since the 600 CPW are way underpowered and slow (The minimum requirements for a one developer workspace for WAS is _twice_ that) - but also very expensive.
