K2: A Mobile Operating System for Heterogeneous Coherence Domains
Felix Xiaozhu Lin, Zhen Wang, Lin Zhong
Article No.: 4
DOI: 10.1145/2699676

Mobile System-on-Chips (SoC) that incorporate heterogeneous coherence domains promise high energy efficiency to a wide range of mobile applications, yet are difficult to program. To exploit the architecture, a desirable, yet missing capability is...

Fireflies: A Secure and Scalable Membership and Gossip Service
Håvard D. Johansen, Robbert Van Renesse, Ymir Vigfusson, Dag Johansen
Article No.: 5
DOI: 10.1145/2701418

An attacker who controls a computer in an overlay network can effectively control the entire overlay network if the mechanism managing membership information can successfully be targeted. This article describes Fireflies, an overlay network...

A Small-Footprint Accelerator for Large-Scale Neural Networks
Tianshi Chen, Shijin Zhang, Shaoli Liu, Zidong Du, Tao Luo, Yuan Gao, Junjie Liu, Dongsheng Wang, Chengyong Wu, Ninghui Sun, Yunji Chen, Olivier Temam
Article No.: 6
DOI: 10.1145/2701417

Machine-learning tasks are becoming pervasive in a broad range of domains, and in a broad range of systems (from embedded systems to data centers). At the same time, a small set of machine-learning algorithms (especially Convolutional and Deep...
