Abstract
A data caching approach is provided for a distributed computing environment employing coherent data caching. The data caching approach includes dynamically deciding whether to associate a priority tag with requested data for a processing unit, wherein the priority tag is to be employed in deciding whether to hold the requested data in a local cache associated with the processing unit. The dynamically deciding includes determining whether latency of arrival of requested data at the processing unit meets a set threshold, and if so, associating the priority tag with the requested data. The priority tag indicates that at least one of the requested data is to be captured in the local cache or the requested data is to be maintained in the local cache over other data without an associated priority tag. In one implementation, the threshold is a programmable threshold, and the local cache is a lookaside cache.
