METHOD, DATA PROCESSING PROGRAM, AND COMPUTER PROGRAM PRODUCT TO COMPENSATE FOR COUPLING OVERHEAD IN A DISTRIBUTED COMPUTING SYSTEM, AND CORRESPONDING OVERHEAD CALCULATOR FOR A DISTRIBUTED COMPUTING SYSTEM AND CORRESPONDING COMPUTER SYSTEM

摘要

An improved method to compensate for coupling overhead in a distributed computing system offering a raw processing capacity, comprising an effective processing capacity (404) and the coupling overhead, is disclosed, wherein the distributed computing system comprises at least one computer system and at least one coupling facility. The method comprises determining a coupling efficiency, determining and adding an amount of missing processing capacity to the effective processing capacity based on the coupling efficiency in a way that the effective processing capacity of the raw processing capacity corresponds to a billable target processing capacity.

1. A method to compensate for coupling overhead 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/or static configuration parameters of said distributed computing system are considered to determine said coupling efficiency.
