"Incremental, Iterative Data Processing with Timely Dataflow" describes Naiad, which combines three classes of dataflow systems, supporting high-throughput batch processing queries, low-latency data stream queries, and iterative programs in a single framework.
Incremental, Iterative Data Processing with Timely Dataflow
We describe the timely dataflow model for distributed computation and its implementation in the Naiad system.
Efficient Parallelization Using Rank Convergence in Dynamic Programming Algorithms
This paper proposes an efficient parallel algorithm for an important class of dynamic programming problems that includes Viterbi, Needleman-Wunsch, Smith-Waterman, and Longest Common Subsequence.
Companies are exploring the use of a "human dialogue interface" to interact with customers and employees more effectively.
Why Data Citation Is a Computational Problem
Using database views to define citable units is the key to specifying and generating citations to data.
Technical Perspective: Jupiter Rising
As "Jupiter Rising" makes clear, many of the Internet mechanisms for maintaining large-scale networks are suboptimal when the datacenter is largely homogeneous, exhibits strong regularity within its structure, and when its bandwidth needs exceed the capabilities of those of any available equipment vendor.
A New Look at the Semantic Web
Seeking to make Web data "smarter" by utilizing a new kind of semantics.
Designing AI Systems that Obey Our Laws and Values
Calling for research on automatic oversight for artificial intelligence systems.
Bad Software Architecture Is a People Problem
When people don't work well together they make bad decisions.
Jupiter Rising: A Decade of Clos Topologies and Centralized Control in Google's Datacenter Network
We present our approach for overcoming the cost, operational complexity, and limited scale endemic to datacenter networks a decade ago.
14 Years of a Learner-Centered Python IDE
How we thought about the JES pedagogical programming environment for students over the last 14 years.
Skills For Success at Different Stages of an IT Professional’s Career
The skills and knowledge that earn promotions are not always enough to ensure success in the new position.
Smart Cities: Concepts, Architectures, Research Opportunities
The aim is to improve cities' management of natural and municipal resources and in turn the quality of life of their citizens.
Verifying Quantitative Reliability For Programs that Execute on Unreliable Hardware
We present Rely, a programming language that enables developers to reason about the quantitative reliability of an application — namely, the probability that it produces the correct result when executed on unreliable hardware.
Ur/Web: A Simple Model For Programming the Web
This paper presents Ur/Web, a domain-specific, statically typed functional programming language that reduces the nest of Web standards for modern Web applications to a simple programming model.
Technical Perspective: Toward Reliable Programming For Unreliable Hardware
"Verifying Quantitative Reliability for Programs that Execute on Unreliable Hardware" by Carbin et al. addresses challenges related to a bug, how likely it is to occur, and how it will affect an application's behavior.
Technical Perspective: Why Didn’t I Think of That?
Until now, the database in a Web application has been treated as a global variable, accessible to all. In "Ur/Web: A Simple Model for Programming the Web," Adam Chlipala suggests a better approach.
ShiViz is a new distributed system debugging visualization tool.
SQL has a brilliant future as a major figure in the pantheon of data representations.
The Hidden Dividends of Microservices
Microservices aren't for every company, and the journey isn't easy.
Shape the Future of Computing
ACM encourages its members to take a direct hand in shaping the future of the association. There are more ways than ever to get involved.
Get InvolvedCommunications of the ACM (CACM) is now a fully Open Access publication.
By opening CACM to the world, we hope to increase engagement among the broader computer science community and encourage non-members to discover the rich resources ACM has to offer.
