PHOENIX

Mats Rimborg, Pedro Trancoso, Gunnar Carlstedt
2017 Proceedings of the International Symposium on Memory Systems - MEMSYS '17  
PHOENIX may achieve 6TFLOPS with a power consumption of up to 42W, which results in a peak energy efficiency of at least 143GFLOPS/W.  ...  A simple estimate shows that for a 4K FFT, PHOENIX achieves 117GFLOPS/W which is more than double of what is achieved by state-of-the-art systems.  ...  ACKNOWLEDGMENTS The authors wish to thank Professor Per Stenström at Chalmers University of Technology for his involvement and valuable contributions to this paper.  ...

Inferring Mesoscale Models of Neural Computation [article]

Thomas Dean
2017 arXiv   pre-print
However, as these techniques grow ever more powerful---allowing us to even contemplate measuring every neuron in entire brain---a new problem arises: how do we make sense of the mountains of data that  ...  Rather than suggest a specific theory, we present a new class of scientific instruments that can enable neuroscientists to design, propose, implement and test mesoscale theories of neural computation.  ...  What sort of independence relationships would such a network exhibit?  ...

On the partial path protection scheme for WDM optical networks and polynomial time computability of primary and secondary paths

Krishnaiyan Thulasiraman, Tie Wang, Weiyi Zhang, Guoliang Xue
2007 Journal of Industrial and Management Optimization  
This fundamental property of the PPP scheme is of great importance in the context of achieving further research advances in the area of protection and restoration of WDM networks.  ...  It is known that the existence of PP implies the existence of PPP while the reverse is not true. We demonstrate a similar result in the case of segmented path protection.  ...  In [7] , Frederick et al. introduce the concept of subgraph routing.  ...

The paper describes the basic building blocks for such a network, the operation of these branches as stirrers, a general linear graph-based theory for the analysis and optimal control of fluidic magneto-hydrodynamic  ...  Equipped with additional, internally located electrodes, the network branches double as stirrers capable of generating chaotic advection.  ...  In contrast, a nearly linear relationship between the flow rate and the current (equation 5) holds over the entire range of interest. In this sense, equation (5) is preferable to equation (4).  ...
