All-optical computing with beyond 100-GHz clock rates

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Gordon H. Y. Li, Midya Parto, Jinhao Ge, Qing-Xin Ji, Maodong Gao | Summary: A computer’s clock rate ultimately determines the minimum time between sequential operations or instructions. Despite exponential advances in electronic computer performance owing to Moore’s Law and increasingly parallel system architectures, computer clock […]

An Exceptionally Powerful, Radiatively Driven Ultrafast Outflow in the Rapidly Accreting AGN REJ1034+396

Kavli Affiliate: Steven Allen | First 5 Authors: Chloe Taylor, Daniel Wilkins, Steven Allen, , | Summary: We report the analysis of ~1Ms of XMM-Newton observations of the rapidly accreting active galactic nucleus REJ1034+396. The 0.3-9 keV EPIC-pn spectra are well described by a model consisting of steep continuum emission from the corona accompanied by […]

Prediction-Assisted Online Distributed Deep Learning Workload Scheduling in GPU Clusters

Kavli Affiliate: Jia Liu | First 5 Authors: Ziyue Luo, Jia Liu, Myungjin Lee, Ness B. Shroff, | Summary: The recent explosive growth of deep learning (DL) models has necessitated a compelling need for efficient job scheduling for distributed deep learning training with mixed parallelisms (DDLwMP) in GPU clusters. This paper proposes an adaptive shortest-remaining-processing-time-first […]

Distinct roles of cortical layer 5 subtypes in associative learning

Kavli Affiliate: Rui Costa | Authors: Sara Moberg, Michele Garibbo, Camille Mazo, Ariel Gilad, Dietmar Schmitz, Rui Ponte Costa, Matthew E Larkum and Naoya Takahashi | Summary: Adaptive behavior is critically dependent on associative learning, where environmental cues are linked with subsequent positive or negative outcomes. In mammals, primary neocortical sensory areas serve as pivotal […]
