Chiplet-based exascale computers At the recent IEEE International Electron Devices Meeting (IEDM), CEA-Leti presented a paper on a 3D chiplet technology that enables exascale-level computing systems. The United States and other nations are working on exascale supercomputers. Today’s supercomputers are measured in floating point operations per second. The world’s fastest supercomputers c... » read more

Cybersecurity for manufacturing The University of Texas at San Antonio (UTSA) has launched a center to address cybersecurity issues in the U.S. manufacturing sector. The center, called the Cybersecurity Manufacturing Innovation Institute (CyManII), is a $111 million public-private partnership. As part of the effort, UTSA will enter into a five-year corporative agreement with the U.S. Depart... » read more

Artificial neural networks have found a variety of commercial applications, from facial recognition to recommendation engines. Compute-in-memory accelerators seek to improve the computational efficiency of these networks by helping to overcome the von Neumann bottleneck. But the success of artificial neural networks also highlights their inadequacies. They replicate only a small subset of th... » read more

Cryogenic memory Researchers at Oak Ridge National Laboratory demonstrated a new cryogenic memory cell circuit design based on coupled arrays of Josephson junctions. Such a memory could help enable exascale and quantum computing. The cells are designed to operate in super cold temperatures and were tested at just 4 Kelvin above absolute zero, about minus 452 degrees Fahrenheit. At these col... » read more

Accelerator-on-chip Researchers at Stanford University and SLAC National Accelerator Laboratory created an electron-accelerator-on-chip. While the technique is much less powerful than standard particle accelerators, it can be much smaller. It relied upon an infrared laser to deliver, in less than a hair’s width, the sort of energy boost that takes microwaves many feet. The team carved ... » read more

Six-angstrom waveguide Engineers at the University of California San Diego, City University of New York, and Johns Hopkins University created the thinnest optical waveguide yet. At only three atoms thick, the team says the waveguide serves as a proof of concept for scaling down optical devices. The waveguide consists of a tungsten disulfide monolayer (made up of one layer of tungsten atoms ... » read more

Exascale supercomputers The Department of Energy’s National Nuclear Security Administration (DOE/NNSA) has signed a contract valued at $600 million with Cray to build NNSA’s first exascale supercomputer. The system, called El Capitan, is expected to be shipped in late 2022. El Capitan will be housed at Lawrence Livermore National Laboratory (LLNL), and will perform research to maintain ... » read more

Biofuels from microorganisms Researchers at Uppsala University are working on adapting microorganisms to be capable of producing useful biofuels out of carbon dioxide and solar energy. The team is focused on a series of modified cyanobacteria that produces the alcohol butanol, said Pia Lindberg, Senior Lecturer at the Department of Chemistry Ångström Laboratory, Uppsala University. "When ... » read more
