New Supercomputer Benchmarks Overdue?
The yardstick used to identify the world’s best-performing supercomputers–the Linpack Benchmark–no longer reflects "real-world usage" and ought to be replaced with a new metric, says Allan Snavely.
A Breakthrough in Algorithm Design
Computer scientists at Carnegie Mellon University have devised an algorithm that might be able to solve a certain class of linear systems much more quickly than today's fastest solvers.
The market model pioneered by Apple and others is transforming the software world — and has profound implications for software companies and their customers.
Developing an IT ecosystem for health could improve — and transform — the practice of medicine.
To ensure the timely publication of articles, Communications created the Virtual Extension to bring readers high-quality articles in an online-only format. The following articles are now available in their entirety to ACM members via the Digital Library.
Replicating Human Errors to Test Network Security
University of Southern California researchers have developed a system for testing the security of computer networks by making computers simulate the type of human errors that leave networks vulnerable.
Trust Develops ‘science Base’ For Cybersecurity
University of California, Berkeley's TRUST is developing a cybersecurity "science base"– a principled approach to developing trustworthy systems in which security is an integral part and not "bolted on like an afterthought."
Franz Alt, one of the founders of ACM and its president from 1950 to 1952, died July 21, 2011 at the age of 100.
Researchers Find Tipping Point to Sway Public Opinion
If 10% of a social network is strongly committed to an opinion, that’s enough to rapidly convert the uncommitted 90% to adopt their point of view, according to a team of researchers at Rensselaer Polytechnic Institute.
It’s not unusual for system administrators to spend long days in the office—and even wind up sleeping in them overnight. Or get paged at 2 A.M. or on Thanksgiving after a server crashes.
Quantum Computing Claims Produce Uncertainty
A Canadian company developing a quantum computer made news in May when it sold a system to defense manufacturer Lockheed-Martin for $10 million, though skeptics question whether the machine made by D-Wave Systems, of Burnaby, British Columbia, could surpass conventional computers. Critics had been somewhat mollified after the company published a paper in the journal Nature showing that their processors were indeed relying on quantum mechanical effects. Nonetheless, experts are not yet convinced D-Wave has created a true quantum computer.
A New Benchmark For Artificial Intelligence
Computers are unable to defeat the world's best Go players, but that may change with the application of a new strategy that promises to revolutionize artificial intelligence.
Supercomputing’s Exaflop Target
The twin challenges of parallelism and energy consumption are enlivening supercomputers' progress.
The Holy Grail of language translation is to develop a machine-based system that can handle the task transparently and accurately.
From the Presidents of the IEEE Computer Society and ACM
As most members of our organizations probably know, there is a great deal of overlap between the products and services offered by the IEEE CS and ACM. In fact, about 27% of ACM members belong to IEEE CS.
To ensure the timely publication of articles, Communications created the Virtual Extension (VE) to bring readers high-quality articles in an online-only format. The following articles are now available to ACM members via the Digital Library.
The Importance Of Analyzing Social Intelligence
Huge amounts of data emanating from Facebook, Twitter, and other social networking sites, which is known collectively as “social intelligence, ” is being gathered, managed, and analyzed. The insights it creates into markets and customers has become one of today's most important business and technology trends.
Mi-Lsamp Boosts Minority STEM Enrollment
MI-LSAMP has managed to increase the number of STEM degrees awarded to minority students by nearly 50% over the last five years. In addition, it has increased overall enrollment in STEM curriculum.
Five Tips To Improve Enterprise Mobile Security
Mobile devices are increasingly connected with an ecosystem of third-party cloud and desktop services outside an enterprise's control. Here's five tips that enterprises — as well as end users — can follow to improve their mobile security.
Games and Learning: Seven Questions For Mary Flanagan
A professor of digital humanities at Dartmouth College, Mary Flanagan has spent her career thinking critically about a topic that most of us take for granted: Play.
Does IBM's Watson represent a distinct breakthrough in machine learning and natural language processing or is the 2,880-core wunderkind merely a solid feat of engineering?
Self-driving cars are inching closer to the assembly line, thanks to promising new projects from Google and the European Union.
How three different individuals in three different countries — Brazil, Egypt, and Japan — use Facebook, Twitter, and other social-media tools.
