A method for managing a cache operates in a data processing system with a system memory and a plurality of processing units (PUs). A first PU determines that one of a plurality of cache lines in a first cache of the first PU must be replaced with a first data block, and determines whether the first data block is a victim cache line from another one of the plurality of PUs. In the event the first data block is not a victim cache line from another one of the plurality of PUs, the first cache does not contain a cache line in coherency state invalid, and the first cache contains a cache line in coherency state moved, the first PU selects a cache line in coherency state moved, stores the first data block in the selected cache line and updates the coherency state of the first data block.
