New Twists in the Intertwining of HPC and AI (Jul 2, 2019)
The alliance between high performance computing and artificial intelligence is proving to be a fruitful one for researchers looking to accelerate scientific discovery in everything from climate prediction and genomics to particle physics and drug discovery. The impetus behind this is to use AI, and machine learning in particular, to augment the predictive capacity of numerical simulations.

Study Uses Supercomputers to Advance Dynamic Earthquake Rupture Models (Jul 1, 2019)
Multi-fault earthquakes can span fault systems of tens to hundreds of kilometers, with ruptures propagating from one segment to another. During the last decade, seismologists have observed several cases of this complicated type of earthquake rupture and are now relying on supercomputers to provide detailed models to better understand the fundamental physical processes that take place during these events, which can have far reaching effects.

Advancing Manufacturing with Simulation-Based Digital Twins (Jul 1, 2019)
The concept of a digital twin—the mirroring of a physical object with a virtual object created by simulation-based engineering—has been around since NASA began using numerical simulation technology and comparing the results to ground-based physical models as it developed and managed early spacecraft.

When Will Quantum Computers Outperform Regular Computers? (Jun 30, 2019)
Any day now, quantum computers will solve a problem too hard for a classical computer to take on. Or at least, that’s what we’ve been hoping. Scientists and companies are racing toward this computing milestone, dubbed quantum supremacy and seemingly just beyond our reach, and if you’ve been following the quantum computing story, you might wonder why we’re not there yet, given all the hype.

It Takes a Whole Community to Drive AI Forward (Jun 30, 2019)
When it comes to achieving ongoing gains with high-performance computing, no individual or organization can do it alone. It takes a large, robust community to drive the continual advances in HPC that are a prerequisite for meeting the growing demands of applications like data analytics and artificial intelligence.

Idle Computer Science Skills are the Devil’s Playthings (Jun 29, 2019)
Take yourself back to the 1980s, the derring-do of Vulcan 607, Peter Davison as Doctor Who and a period when mainframe time at UK establishments of higher learning was a precious thing. Young Charles was a first year student, studying Computer Science and, by all accounts, a bit of a bright spark. Perhaps a tad too bright.

The Mind Can’t Be Just a Computer (Jun 29, 2019)
Kurt Gödel (1906–1978) proved that there are truths in mathematical logic that lie outside mathematical logic. An Austrian-born friend of Albert Einstein, Gödel has stirred up debate for decades with his odd, ingenious result. He inspired mathematical platonists like physicist Roger Penrose, Rouse Ball Professor of Mathematics at Oxford University, to base his philosophical argument against mechanism, or, if you will, computationalism — the idea that all thinking is at root computer progra...

Bitcoin Causing Carbon Dioxide Emissions Comparable to Las Vegas or Hamburg (Jun 28, 2019)
Although Bitcoin is a virtual currency, the energy consumption associated with its use is very real. For a Bitcoin transfer to be executed and validated, a mathematical puzzle must be solved by an arbitrary computer in the global Bitcoin network. The network, which anyone can join, rewards the puzzle solvers in Bitcoin. The computing capacity used in this process -- known as Bitcoin mining -- has increased rapidly in recent years. Statistics show that it quadrupled in 2018 alone.

First Blood-Brain Barrier Chip Using Stem Cells Developed by Ben-Gurion University Researchers (Jun 28, 2019)
Researchers at Ben-Gurion University of the Negev (BGU) and Cedars-Sinai Medical Center in Los Angeles have, for the first time, duplicated a patient's blood-brain barrier (BBB), creating a human BBB chip with stem cells, which can be used to develop personalized medicine and new techniques to research brain disorders.

Spintronic Memory Cells for Neural Networks (Jun 27, 2019)
In recent years, researchers have proposed a wide variety of hardware implementations for feed-forward artificial neural networks. These implementations include three key components: a dot-product engine that can compute convolution and fully-connected layer operations, memory elements to store intermediate inter and intra-layer results, and other components that can compute non-linear activation functions.

Preparing Scientific Applications for Exascale Computing (Jun 27, 2019)
Exascale computers are soon expected to debut, including Frontier at the U.S. Department of Energy's (DOE) Oak Ridge Leadership Computing Facility (OLCF) and Aurora at the Argonne Leadership Computing Facility (ALCF), both DOE Office of Science User Facilities, in 2021. These next-generation computing systems are projected to surpass the speed of today's most powerful supercomputers by five to 10 times. This performance boost will enable scientists to tackle problems that are otherwise unsolvabl...

University Subject Profile: Computer Science and Information Systems (Jun 26, 2019)
At its heart, computer science is about problem-solving. Students study the design of software and hardware used to provide solutions for a variety of business, scientific and social problems. Most computing courses focus on software engineering – things like database design, network systems, computer hardware and the internet. But there are other options, such as virtual reality, artificial intelligence, cybernetics, multimedia and games design, and apps design.

Harvey Mudd President Maria Klawe Has a Message for Computer Science Grads – and the Tech Industry (Jun 26, 2019)
In the 13 years since Maria Klawe took over as president of Harvey Mudd College, she has surprised skeptics and achieved a milestone that has confounded most institutions of higher education. Today, 50 percent of Harvey Mudd graduates with degrees in science, technology, engineering, and mathematics are women, and students of color are on the rise at the elite technical college.

NSF 2026 Idea Machine (Jun 25, 2019)

Will Analog AI Make Mythic a Unicorn? (Jun 25, 2019)
There are two trends converging in AI inference and so far, only a small number of companies are enmeshed. The first trend takes us back to the future with analog compute engines, which promise much lower power and potential cost, but with some impacts to complexity creation and avoidance. More on that shortly.

Past Efforts to Reshape American Science Education Offer Lessons for Future Reformers (Jun 24, 2019)
Compared with reading, writing, and arithmetic, science is a relative newcomer to the primary and secondary school curriculum, emerging only in the late 19th century. Nevertheless, proponents of the subject have established it as central to what an educated person needs to know, not least because of the promise of good jobs in scientific fields.

Teachers, Not Online Course, the Key to Computer Science Growth (Jun 24, 2019)
