Abstract:
A garbage collection facility is provided for memory management within a computer. The facility implements, in part, grouping of infrequently accessed data units in a designated transient memory area, and includes designating an area of the memory as a transient memory area and an area as a conventional memory area, and counting, for each data unit in the transient or conventional memory areas a number of accesses to the data unit. The counting provides a respective access count for each data unit. For each data unit in the transient memory area or the conventional memory area, a determination is made whether the respective access count is below a transient threshold ascertained to separate frequently accessed data units and infrequently used data units. Data units with respective access counts below the transient threshold are grouped together as transient data units within the transient memory area.
