Sora: High-Performance Software Radio Using General-Purpose Multi-Core Processors
Sora, a fully programmable software radio platform on commodity PC architectures, combines the performance and fidelity of hardware software-defined radio platforms with the programmability and flexibility of general-purpose processor SDR platforms.
Scholarly Publishing Model Needs an Update
Science demands an overhaul of the well-established system of peer-review in scholarly communication. The current system is outmoded, inefficient, and slow. The only question is how!
Topic Models vs. Unstructured Data
With topic modeling, scientists can explore and understand huge collections of unlabeled information.
What are Bayesian networks and why are their applications growing across all fields?
IBM’s Single-Processor Supercomputer Efforts
Imagine a CPU designed to issue and execute up to seven instructions per clock cycle, with a clock rate 10 times faster than the reigning supercomputer. This is the ACS-1 supercomputer designed more than 40 years ago.
A Conversation with Ed Catmull
Pixar's president Ed Catmull sits down with Stanford professor (and former Pixar-ian) Pat Hanrahan to reflect on the blending of art and technology.
Business Impact of Web 2.0 Technologies
What do wikis, blogs, podcasts, social networks, virtual worlds, and the rest do for corporate productivity and management?
Sir, Please Step Away from the ASR-33!
To move forward with programming languages we must first break free from the tyranny of ASCII.
Understanding Throughput-Oriented Architectures
For workloads with abundant parallelism, GPUs deliver higher peak computational throughput than latency-oriented CPUs.
Supporting Ubiquitous Location Information in Interworking 3G and Wireless Networks
Positioning mobile devices in the third generation of wireless communication networks is crucial to many commercial services. However, positioning techniques vary by accuracy, implementation cost, and typical application scenarios.
Today's data deluge is leading to new approaches to visualize, analyze, and catalog enormous datasets.
Using Complexity to Protect Elections
Computational complexity may truly be the shield against election manipulation.
Barbara Liskov Keynote Grace Hopper Conference

Photoshop Scalability: Keeping It Simple
Clem Cole and Russell Williams discuss Photoshop's long history with parallelism, and what is now seen as the chief challenge.
Thinking Clearly About Performance, Part 2
More important principles to keep in mind when designing high-performance software.
Tackling Architectural Complexity with Modeling
Component models can help diagnose architectural problems in both new and existing systems.
A Neuromorphic Approach to Computer Vision
Neuroscience is beginning to inspire a new generation of seeing machines.
A novel approach to computational logic is reaching maturity, opening up opening up new vistas in programming languages, proof nets, and security applications.
Originally invented for music/data sharing and volunteer computing, P2P systems have become an efficient means for delivering content and innovative services.
Technical Perspective: Belief Propagation
Nearly every modern tracking system is based on the seminal work of Rudolf Kalman who developed the optimal fusion algorithm for linear dynamics under Gaussian noise.
In Search of Database Consistency
Michael Stonebraker discusses the implications of the CAP theorem on database management system applications that span multiple processing sites.
Difference Engine: Harnessing Memory Redundancy in Virtual Machines
Virtual machine monitors are a popular platform for Internet hosting centers and cloud-based compute services. But main memory is not amenable to multiplexed hardware resources and is often a bottleneck in achieving higher degrees of consolidation.
Technical Perspective: A VM ‘Engine’ That Makes a Difference
The past decade has witnessed a renaissance in server virtualization. Diwaker Gupta et al. present a novel approach for significantly improving the efficiency of virtualized servers.
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.
