Patent ID: 8677372

Claim:
A method to compensate for coupling overhead of a coupling system in a distributed computing system offering a raw processing capacity, the raw processing capacity comprising an effective processing capacity and the coupling overhead, wherein said distributed computing system comprises at least one computer system and at least one coupling facility, the method comprising: determining a coupling efficiency; and determining and adding an amount of missing processing capacity to said effective processing capacity based on said coupling efficiency in a way, that the effective processing capacity of said raw processing capacity corresponds to a billable target processing capacity, wherein dynamic coupling overhead indicators and static configuration parameters of said distributed computing system are considered to determine said coupling efficiency, and said dynamic coupling overhead indicators comprise information about applications or software code running on said distributed computing system, information about intensity of data sharing between components of said distributed computing system and about rates of coupling overhead critical instructions and the coupling efficiency corresponds to a ratio of said effective processing capacity to said raw processing capacity.
