Abstract
The present invention relates to means, a method and a computer program product of administrating in a computer system a global data element shared by a multitude of exploiters within said computer system for reducing contention among said exploiters.It is suggested to execute a first step by a first exploiter of accumulating one or a multitude of modifications performed by said first exploiter with respect to the current contents of said global data element into a first local data element not shared by other exploiters.In a second step executed by the first exploiter a size of the accumulated modifications in the first local data element with respect to the current contents of the global data element is determined. Moreover it is determined, if said size exceeds a specified quantum.If said size exceeds the specified quantum, the global data element is updated with the accumulated modifications as new contents.
