Optimal network performance is critical to efficient parallel scaling for communication-bound applications on large machines. With wormhole routing, no-load latencies do not increase significantly with number of hops traveled. Yet, we, and others have ...

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 ...

With the trend towards increasing number of cores in a multicore processors, the on-chip network that connects the cores needs to scale efficiently. In this work, we propose the use of high-radix networks in on-chip networks and describe how the ...
