Future rack-scale computers will comprise a large number of tightly integrated systems-on-chip, interconnected by a switch-less internal fabric. This design enables thousands of cores per rack and provides high bandwidth for rack-scale applications. Most of the benefits promised by these new architectures, however, can only be achieved with adequate support from the software stack.<\/p>\n<p>In this paper, we take a step in this direction by focusing on the network stack for rack-scale computers. Using routing and rate control as examples, we show how the peculiarities of rack architectures allow for new approaches that are attuned to the underlying hardware.
