Targeting future CMP based systems with NUCA type L2 caches, this paper proposes a novel data migration algorithm for parallel applications and evaluates it. The goal of this migration scheme is to determine a suitable location for each data block within a large L2 space at any given point during execution. A unique characteristic of the proposed scheme is that it models the problem of optimal data placement in the L2 cache space as a two-dimensional
post office placement problem, presents a practical architectural implementation of this model, and gives a detailed evaluation of the proposed implementation. In our experimental evaluation, we also compare our approach to a previously-proposed NUCA management scheme using
applications from the specomp suite, oltp, specjbb, and specweb.
