Spatial Locality Speculation to Reduce Energy in Chip-Multiprocessor Networks-on-Chip

Boris Robert Grot

As processor chips become increasingly parallel, an efficient communication substrate is critical for meeting performance and energy targets. In this work, we target the root cause of network energy consumption through techniques that reduce link and route ...

Optimizing Data-Center TCO with Scale-Out Processors

Babak Falsafi, Pejman Lotfi Kamran, Boris Robert Grot

Performance and total cost of ownership (TCO) are key optimization metrics in large-scale data centers. According to these metrics, data centers designed with conventional server processors are inefficient. Recently introduced processors based on low-power ...
