The LPAR level charts use standard HARLPC file data elements to derive the dispatch variables:
ENGDISPT – Total ICF Engine Dispatch (Set to LPCSIDTM – Total shared ICF Proc. Dispatch Time / 3600)
ENGDISPE – Effective ICF Engine Dispatch (Set to LPCSIEDT – Total Shr ICF Proc. Effec.Dispatch Time / 3600)
The vertical bars, for the LPAR level charts, show the total and effective dispatch of the logical ICF 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 ICF engines could, at full utilization, provide three hours of dispatch time in one hour.
LPCAVICF - Avg Number of Active ICF Processors
This horizontal reference line, for the LPAR level charts, show the average number of logical ICF 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.
