Design of CA based scheme for evenhanded data migration in CMPs

摘要

This work reports realization of close to accurate data migration in Chip Multiprocessors (CMPs). The periodic boundary cellular automata (PBCA) is introduced to accept the requests from processor cores competing for a data block and to perform accurate density classification of the requesting processors. The CA enables identification of populated region of requesting cores and thereby points to the area of migration. The design is enriched to favor the processor cores in isolation and to decide on the area of migration to avoid performance loss of such processors.
