The main focus of "Heavy Hitters via Cluster-Preserving Clustering" by Kasper Green Larsen et al. is on building up sufficient information to allow a more effective...Graham Cormode From Communications of the ACM | August 2019
We develop a new algorithm for the turnstile heavy hitters problem in general turnstile streams, the EXPANDERSKETCH, which finds the approximate top-k items in...Kasper Green Larsen, Jelani Nelson, Huy L. Nguyễn, Mikkel Thorup From Communications of the ACM | August 2019
Umesh Vazirani and Thomas Vidick's "Fully Device Independent Quantum Key Distribution" provides an unexpectedly simple and elegant secure protocol solution, indeed...Gilles Brassard From Communications of the ACM | April 2019
We rigorously provide the device-independent security of an entanglement-based protocol building on Ekert's original proposal for quantum key distribution.

Whether there exists a deterministic parallel algorithm for bipartite matching remains an outstanding question at the frontiers of our understanding of the role...Nisheeth K. Vishnoi From Communications of the ACM | March 2019
In this article, we give an almost complete derandomization of the Isolation Lemma for perfect matchings in bipartite graphs.

"Predicting Program Properties from 'Big Code'" presents new techniques for leveraging big code to automate two programming activities: selecting understandable...Martin C. Rinard From Communications of the ACM | March 2019
The authors of "Distributed Strategies for Computational Sprints" bring the rich theory of allocating scarce resources to the challenge of managing computational...Thomas F. Wenisch From Communications of the ACM | February 2019
We describe a computational sprinting architecture in which many, independent chip multiprocessors share a power supply and sprints are constrained by the chips'...Songchun Fan, Seyed Majid Zahedi, Benjamin C. Lee From Communications of the ACM | February 2019
"Scalable Computation of High-Order Optimization Queries," by Brucato et al., makes a case for marrying the well-established paradigms of constrained optimization...Surajit Chaudhuri From Communications of the ACM | February 2019
We present a complete system that supports package queries, a new query model that extends traditional database queries to handle complex constraints and preferences...Matteo Brucato, Azza Abouzied, Alexandra Meliou From Communications of the ACM | February 2019
"Bringing the Web Up to Speed with WebAssembly," by Rossberg et al., gives an overview of the initial design of WebAssembly, a new low-level programming language...Anders Møller From Communications of the ACM | December 2018
WebAssembly is the first mainstream language designed from the start with a formal semantics. It not only demonstrates the feasibility of applying formal techniques...Andreas Rossberg, Ben L.

In "How to Implement Any Concurrent Data Structure," Calciu et al. show that a concurrent data structure can be built automatically and that its performance is...Tim Harris From Communications of the ACM | December 2018
We propose a method called Node Replication (NR) to implement any concurrent data structure.

"Enabling Highly Scalable Remote Memory Access Programming with MPI-3 One Sided" convincingly shows that the potential of MPI one-sided communication can be realized...Marc Snir From Communications of the ACM | October 2018
In this work, we design and develop bufferless protocols that demonstrate how to implement the MPI-3 RMA interface and support scaling to millions of cores.
