The LPAR level charts use standard HARLPC file data elements, to derive the dispatch variables:
ENGDISPT – Total IFL Engine Dispatch (Set to LPCSNDTM – Total shared IFL Proc. Dispatch Time / 3600)
ENGDISPE – Effective IFL Engine Dispatch (Set to LPCSNEDT – Total Shr IFL Proc. Effec.Dispatch Time / 3600)
The vertical bars, for the LPAR level charts, show the total and effective dispatch of the logical IFL processors assigned to the LPAR. The total and effective dispatch times are divided by 3600 to convert from seconds of dispatch to hours of dispatch. Because one engine can be dispatched a maximum of one hour, per hour, this conversion allows the dispatch of the engine pool to be represented as logical engine dispatch hour equivalents. For example, three logical IFL engines could, at full utilization, provide three hours of dispatch time in one hour.
LPCAVIFL - Avg Number of Active IFL Processors
This horizontal reference line, for the LPAR level charts, show the average number of logical IFL processors assigned to the LPAR. The actual dispatch engine equivalents, charted with the vertical bars, can reach, but should never exceed this line. IBM features like the Intelligent Resource Director (IRD) can activate and deactivate logical processors at the LPAR level—so this line may not reflect a constant value over the entire day.
