A new paper published in Optica, “Focusing on bandwidth: achromatic metalens limits,” details the finding of some fundamental limits on so-called “metalenses,” ultra-thin flat lenses which have shown... Read more about Exploring the theoretical limits of metalenses

Systems across the computing spectrum, from cell phones to supercomputers, are increasingly using a heterogeneous mix of general-purpose multicores augmented with programmable graphics processing units (GPUs).
Systems across the computing spectrum, from cell phones to supercomputers, are increasingly using a heterogeneous mix of general-purpose multicores augmented with programmable graphics processing units (GPUs). Heterogeneity offers a balance between programmability and efficiency, but can also significantly increase complexity at all levels of the computing stack. This project is exploring a new approach based on explicitly encoding and executing a loop iteration space with the goal of elegantly unifying these two types of processors into a single homogeneous computational substrate.
Professor Christopher Batten has been an assistant professor in the School of Electrical and Computer Engineering at Cornell University since January 2010. His research focuses on energy-efficient parallel computer architecture for both high-performance and embedded applications. Christopher received his Ph.D. in electrical engineering and computer science from the Massachusetts Institute of Technology in 2010. From 2007 to 2009, he was a visiting scholar in the new Parallel Computing Laboratory at the University of California at Berkeley. Professor Batten received his M.Phil. in engineering as a Churchill Scholar at the University of Cambridge in 2000, and received his B.S. in electrical engineering as a Jefferson Scholar at the University of Virginia in 1999.
