Welcome to SC10: Opening Keynote, Top500 List
SC10—the premier conference for supercomputing—has begun. This post touches on a few highlights from the first day of the full technical program, including the keynote by Clayton Christensen, the official release of the Top500 list, and some observations on the exhibit floor.
Watts Humphrey: In Honor of a Pioneer
Watts Humphrey left us a few weeks ago. His contributions to professional software engineering have been essential.
The Divergent Online News Preferences of Journalists and Readers

Keeping Bits Safe: How Hard Can It Be?
As storage systems grow larger and larger, protecting their data for long-term storage is becoming ever more challenging.
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.
Cloud computing offers many advantages, but also involves security risks. Fortunately, researchers are devising some ingenious solutions.
Why Isn’t Cyberspace More Secure?
Evaluating governmental actions—and inactions—toward improving cyber security and addressing future challenges.
Sensor Networks For the Sciences
Lessons from the field derived from developing wireless sensor networks for monitoring active and hazardous volcanoes.
Technical Perspective: Data Races Are Evil with No Exceptions
Exploiting parallelism has become the primary means to higher performance. Shared memory is a pervasively used programming model. Unfortunately, shared-memory programs are notoriously prone to subtle bugs, often due to data races.
FastTrack: Efficient and Precise Dynamic Race Detection
Multithreaded programs are notoriously prone to race conditions. Prior work developed precise dynamic race detectors that never report false alarms. However, these checkers employ expensive data structures that result in significant performance overhead.
Goldilocks: A Race-Aware Java Runtime
GOLDILOCKS is a Java runtime that monitors program executions and throws a DataRaceException when a data race is about to occur. This prevents racy accesses from taking place, and allows race conditions to be handled before they cause errors.
Why Do Software Startups Patent (or Not)?
Assessing the controversial results of a recent empirical study of the role of intellectual property in software startups.
Betwixt and between ubiquitous consumer software and the ethereal realm of ultra-high-performance computing, lies the excluded middle, the world of day-to-day computational science problems.
Can Randomly Generated Code Fix Software Bugs?
Can the principles of evolution be applied to software code and used to improve it? Stephanie Forrest thinks so—and has some encouraging data to prove it.
Common Misconceptions About Software Engineering
Many undergraduates have misconceptions about software engineering that lead to an "impoverished" view of industry that and hinder their transition to the workplace.
Platforms and Services: Understanding the Resurgence of Apple
Combining new consumer devices and Internet platforms with online services and content is proving to be a successful strategy.
Score: Agile Research Group Management
Adapting agile software development methodology toward more efficient management of academic research groups.
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.
Tony Hey talks about Jim Gray and his vision of a new era of collaborative, data-intensive science.
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.
