GARBAGE COLLECTION FOR SELECTING REGION TO RECLAIM ON BASIS OF UPDATE TO REFERENCE-SOURCE INFORMATION

摘要

The present invention further optimizes region-reclaiming efficiency in a GC process for dividing and managing memory regions. To this end, a computer having a calculation device and a memory also has: a storage unit for storing, per storage region, the reference-source information for data to be stored in a plurality of storage regions assigned to the memory; and a control unit for determining that a storage region in which updated reference source information differs from the reference source information stored in the storage unit is a region which should be reclaimed.
