Abstract
For a flexible replication with skewed mapping in a multi-core chip, a request for a cache line is received, at a receiver core in the multi-core chip from a requester core in the multi-core chip. The receiver and requester cores comprise electronic circuits. The multi-core chip comprises a set of cores including the receiver and the requester cores. A target core is identified from the request to which the request is targeted. A determination is made whether the target core includes the requester core in a neighborhood of the target core, the neighborhood including a first subset of cores mapped to the target core according to a skewed mapping. The cache line is replicated, responsive to the determining being negative, from the target core to a replication core. The cache line is provided from the replication core to the requester core.
