Ceremorphic unveils plans to build supercomputer infrastructure on 5 nanometer chips

by Leave a Comment

Supercomputing startup Ceremorphic has unveiled plans to deliver a complete silicon system built on 5 nanometer infrastructure.

The company says its system will provide the performance needed for next-generation applications such as artificial intelligence model training, high-performance computing, automotive processing, drug discovery, and metaverse processing.

Designed in advanced silicon geometry (TSMC 5nm node), this new architecture was built from the ground up to solve today’s high-performance computing problems in reliability, security and energy consumption to serve all performance-demanding market segments.

Columbia Engineering team builds first hacker-resistant cloud software system

by

Whenever you buy something on Amazon, your customer data is automatically updated and stored on thousands of virtual machines in the cloud.

For businesses like Amazon, ensuring the safety and security of the data of its millions of customers is essential. This is true for large and small organizations alike. But up to now, there has been no way to guarantee that a software system is secure from bugs, hackers, and vulnerabilities.

Columbia Engineering researchers may have solved this security issue. They have developed SeKVM, the first system that guarantees – through a mathematical proof – the security of virtual machines in the cloud. In a new paper to be presented on May 26, 2021, at the 42nd IEEE Symposium on Security & Privacy, the researchers hope to lay the foundation for future innovations in system software verification, leading to a new generation of cyber-resilient system software.

New nanoscale device for spin technology

by

Researchers at Aalto University have developed a new device for spintronics. The results have been published in the journal Nature Communications, and mark a step towards the goal of using spintronics to make computer chips and devices for data processing and communication technology that are small and powerful.

Traditional electronics uses electrical charge to carry out computations that power most of our day-to-day technology. However, engineers are unable to make electronics do calculations faster, as moving charge creates heat, and we’re at the limits of how small and fast chips can get before overheating.

Because electronics can’t be made smaller, there are concerns that computers won’t be able to get more powerful and cheaper at the same rate they have been for the past 7 decades. This is where spintronics comes in. [Read more…] about New nanoscale device for spin technology

New tech builds ultralow-loss integrated photonic circuits

by

Encoding information into light, and transmitting it through optical fibers lies at the core of optical communications. With an incredibly low loss of 0.2 dB/km, optical fibers made from silica have laid the foundations of today’s global telecommunication networks and our information society.

Such ultralow optical loss is equally essential for integrated photonics, which enable the synthesis, processing and detection of optical signals using on-chip waveguides.

Today, a number of innovative technologies are based on integrated photonics, including semiconductor lasers, modulators, and photodetectors, and are used extensively in data centers, communications, sensing and computing.

Does watching Netflix or having Zoom meetings leave a carbon footprint?

by

When you think about your carbon footprint, what comes to mind? Driving and flying, probably. Perhaps home energy consumption or those daily Amazon deliveries.

But what about watching Netflix or having Zoom meetings? Ever thought about the carbon footprint of the silicon chips inside your phone, smartwatch or the countless other devices inside your home?

Every aspect of modern computing, from the smallest chip to the largest data center comes with a carbon price tag. For the better part of a century, the tech industry and the field of computation as a whole have focused on building smaller, faster, more powerful devices – but few have considered their overall environmental impact.
