In response to a data request, a victim cache line is selected for castout from a first lower level cache of a first processing unit, and a target lower level cache of one of the plurality of processing units is selected based upon architectural proximity of the target lower level cache to a home system memory to which the address of the victim cache line is assigned. The first processing unit issues on the interconnect fabric a lateral castout (LCO) command that identifies the victim cache line to be castout from the first lower level cache and indicates that the target lower level cache is an intended destination. In response to a coherence response indicating success of the LCO command, the victim cache line is removed from the first lower level cache and held in the second lower level cache."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Victim cache lateral castout targeting","description":"A data processing system includes a plurality of processing units coupled by an interconnect fabric.
