3、 IBM 7th floor,Glendale,California,USA 91203ABSTRACTThis session begins with a conceptual explanation of each layer of the PowerVM CPU nomenclaturebefore introducing the realization of CPUtime recycling at SMT8.This session is deconstructed from what AIX shows us about AIX-on-PowerVM;this session is

4、 based on what AIX shows us about each layer supporting AIX-on-PowerVM.Understanding this structure is the first step towards implementing the tactical practices detailed in the next two sessions.Beyond what AIX shows us,there are no references about:The 6 layers of the PowerVM CPU nomenclature at S
