Communication Locality Analysis of Triplet-Based Hierarchical Interconnection Network in Chip Multiprocessor

چکیده
Interconnection topology inside chip multiprocessor acts as fundamental role in communication locality. Considering compiler optimization data locality has been an inmost hypothesis in the high performance computing. Conversely, data locality sphere has several troubles when its degree of dimension is two or higher. In mesh network of two dimensions, each core is connected with its four neighbors. The data locality can potentially be exploited in two dimensions considering the specified processor’s perspective. A TripletBased Hierarchical Interconnection Network (TBHIN) has straightforward topology and fractal attribute for chip multiprocessor. In this paper, a static (no contention) performance analysis of TBHIN and 2-D mesh is presented, based on the premise of locality in communication. The dynamic (contention) software simulation of TBHIN shows that the stronger the locality in communication, the lower the delay of the communication.

This paper evaluates the Triplet Based Architecture, TriBA – a new idea in chip multiprocessor architectures and a class of Direct Interconnection Network (DIN). TriBA consists of a 2D grid of small, programmable processing units, each physically connected to its three neighbors so that advantageous features of group locality can be fully and efficiently utilized. Any communication model can be...
متن کاملTriplet-based Topology for On-chip Networks
Most CMPs use on-chip network to connect cores and tend to integrate more simple cores on a single die. As the number of cores increases, on-chip network will play an important role in the performance of future CMPs. Due to the tradeoff between the performance and area constraint in on-chip network designs, we propose the use of triplet-based topology in on-chip interconnection networks and dem...
