Technical Perspective: Jupiter Rising
As "Jupiter Rising" makes clear, many of the Internet mechanisms for maintaining large-scale networks are suboptimal when the datacenter is largely homogeneous, exhibits strong regularity within its structure, and when its bandwidth…

Imaging the Propagation of Light Through Scenes at Picosecond Resolution
We present a novel imaging technique, which we call femtophotography, to capture and visualize the propagation of light through table-top scenes with an effective exposure time of 1.85 ps per frame.

Jupiter Rising: A Decade of Clos Topologies and Centralized Control in Google's Datacenter Network
We present our approach for overcoming the cost, operational complexity, and limited scale endemic to datacenter networks a decade ago.

Technical Perspective: The Dawn of Computational Light Transport
What would the world look like if we had a chance to observe it with a trillion frame-per-second video camera? "Imaging the Propagation of Light through Scenes at Picosecond Resolution" by Velten et al. represents an audacious…
