Nvidia Details Grace Hopper CPU Superchip Design: 144 Cores on 4N TSMC Process

Posted by in category: computing

Nvidia shared more performance benchmarks, but as with all vendor-provided performance data, you should take these numbers with a grain of salt. These benchmarks also come with the added caveat that they are conducted pre-silicon, meaning they’re emulated projections that haven’t been tested with actual silicon yet and are “subject to change.” As such, sprinkle some extra salt.

Nvidia’s new benchmark here is the score of 370 with a single Grace CPU in the SpecIntRate 2017 benchmark. This places the chips right at the range we would expect — Nvidia has already shared a multi-CPU benchmark, claiming a score of 740 for two Grace CPUs in the SpecIntRate2017 benchmark. Obviously, this suggests a linear scaling improvement with two chips.

AMD’s current-gen EPYC Milan chips, the current performance leader in the data center, have posted SPEC results ranging from 382 to 424 apiece, meaning the highest-end x86 chips will still hold the lead. However, Nvidia’s solution will have many other advantages, such as power efficiency and a more GPU-friendly design.

Newly discovered magnetic interactions could lead to novel ways to manipulate electron flow

Posted by in categories: computing, particle physics, quantum physics

Newly discovered magnetic interactions in the Kagome layered topological magnet TbMn6Sn6 could be the key to customizing how electrons flow through these materials. Scientists from the U.S. Department of Energy’s Ames National Laboratory and Oak Ridge National Laboratory conducted an in-depth investigation of TbMn6Sn6 to better understand the material and its magnetic characteristics. These results could impact future technology advancements in fields such as quantum computing, magnetic storage media, and high-precision sensors.

Kagomes are a type of material whose structure is named after a traditional Japanese basket weaving technique. The weave produces a pattern of hexagons surrounded by triangles and vice-versa. The arrangement of the atoms in Kagome metals reproduces the weaving pattern. This characteristic causes electrons within the material to behave in unique ways.

Solid materials have controlled by the characteristics of their electronic band structure. The band structure is strongly dependent on the geometry of the atomic lattice, and sometimes bands may display special shapes such as cones. These special shapes, called topological features, are responsible for the unique ways electrons behave in these materials. The Kagome structure in particular leads to complex and potentially tunable features in the electronic bands.

Open-source software enables researchers to visualize nanoscale structures in real time

Posted by in categories: computing, nanotechnology, sustainability, transportation

Computer chip designers, materials scientists, biologists and other scientists now have an unprecedented level of access to the world of nanoscale materials thanks to 3D visualization software that connects directly to an electron microscope, enabling researchers to see and manipulate 3D visualizations of nanomaterials in real time.

Developed by a University of Michigan-led team of engineers and software developers, the capabilities are included in a new beta version of tomviz, an open-source 3D data visualization tool that’s already used by tens of thousands of researchers. The new version reinvents the visualization process, making it possible to go from microscope samples to 3D visualizations in minutes instead of days.

Schrödinger Was Wrong: New Research Overturns 100-Year-Old Understanding of Color Perception

Posted by in categories: computing, mathematics, space

A paradigm shift away from the 3D mathematical description developed by Schrödinger and others to describe how we see color could result in more vibrant computer displays, TVs, textiles, printed materials, and more.

New research corrects a significant error in the 3D mathematical space developed by the Nobel Prize-winning physicist Erwin Schrödinger and others to describe how your eye distinguishes one color from another. This incorrect model has been used by scientists and industry for more than 100 years. The study has the potential to boost scientific data visualizations, improve televisions, and recalibrate the textile and paint industries.

New quantum technology combines free electrons and photons

Posted by in categories: computing, internet, particle physics, quantum physics

Faster computers, tap-proof communication, better car sensors—quantum technologies have the potential to revolutionize our lives just as the invention of computers or the internet once did. Experts worldwide are trying to implement findings from basic research into quantum technologies. To this end, they often require individual particles, such as photons—the elementary particles of light—with tailored properties.

However, obtaining individual particles is complicated and requires intricate methods. In a study recently published in the journal Science, researchers now present a new method that simultaneously generates two individual particles in form of a pair.

Negative digital media effects

Posted by in categories: computing, mobile phones, neuroscience

Smartphones, tablets, computer screens — all digital media has detrimental effects on your brain. That is a position that Professor Manfred Spitzer, a neuroscientist and author of several books, defends. You might like what you’ll hear, you might not, but don’t say that you haven’t been warned. Especially if you have kids running around with smartphones all day long.

Breaking: Scientists Have Reversed Time with a Quantum Computer

Posted by in categories: computing, quantum physics

Scientists have reversed the direction of time with a quantum computer.

The breakthrough study seems to contradict basic laws of physics and could alter our understanding of the processes governing the universe.

In a development that also represents a major advance in our understanding of quantum computers, by using electrons and the strange world of quantum mechanics, researchers were able to turn back time in an experiment that is the equivalent of causing a broken rack of pool balls to go back into place.
