US scientists have unveiled the world’s most powerful and smartest scientific supercomputer that can complete over 200,000 trillion calculations per second – providing unprecedented computing power for research in energy, advanced materials and artificial intelligence (AI). The US Department of Energy’s Oak Ridge National Laboratory (ORNL) supercomputer called Summit will be eight times more powerful than its previous top-ranked system, Titan.
For certain scientific applications, Summit will also be capable of more than three billion billion mixed precision calculations per second, or 3.3 exaops. “Summit will empower scientists to address a wide range of new challenges, accelerate discovery, spur innovation and above all, benefit the American people,” said Rick Perry, Secretary of Energy. The IBM AC922 system consists of 4,608 compute servers, each containing two 22-core IBM Power9 processors and six NVIDIA Tesla V100 graphics processing unit accelerators, interconnected with dual-rail Mellanox EDR 100 Gb/s InfiniBand.
Summit also possesses more than 10 petabytes of memory paired with fast, high-bandwidth pathways for efficient data movement. The combination of cutting-edge hardware and robust data subsystems marks an evolution of the hybrid CPU-GPU architecture successfully pioneered by the 27-petaflops Titan in 2012. ORNL researchers have figured out how to harness the power and intelligence of Summit’s state-of-art architecture to successfully run the world’s first exascale scientific calculation.
Scientists led by ORNL’s Dan Jacobson and Wayne Joubert has leveraged the intelligence of the machine to run a 1.88 exaops comparative genomics calculation relevant to research in bioenergy and human health.
The mixed precision exaops calculation produced identical results to more time-consuming 64-bit calculations previously run on Titan. In addition to scientific modeling and simulation, Summit offers unparalleled opportunities for the integration of AI and scientific discovery, enabling researchers to apply techniques like machine learning and deep learning to problems in human health, high-energy physics, materials discovery and other areas.
“Summit takes accelerated computing to the next level, with more computing power, more memory, an enormous high-performance file system and fast data paths to tie it all together. That means researchers will be able to get more accurate results faster,” said Jeff Nichols, ORNL associate laboratory director for computing and computational sciences. “Summit’s AI-optimised hardware also gives researchers an incredible platform for analyzing massive datasets and creating intelligent software to accelerate the pace of discovery,” he said.

Oculus VR has launched its next-generation Rift virtual reality headset. The new Oculus Rift S features an inside-out tracking which eliminates the need for any external sensors. The Rift S also offers a higher-resolution screen compared to its predecessor. Oculus has announced that the Rift S head-mounted display will ship this Spring at a price of $399 (roughly Rs. 27,300). The company hasn’t revealed an exact launch date yet.
Oculus says it has collaborated with electronics giant Lenovo to develop the Oculus Rift S. The Rift S isn’t quite a major upgrade over the previous headset but aims to offer a higher quality VR experience and better ergonomics.
The Oculus Rift S and its predecessor still share the same core platform, which means users can access VR content created for either of the headsets. Oculus has also maintained the same PC requirements for the new Rift S as the original Rift.
Oculus will also enable cross-buy and cross-play features, enabling users to upgrade their hardware and still have their library accessible as it is.
Oculus Rift S virtual reality headset features a new high-resolution display with improved Fresnel lenses. The display panel offers a resolution of 2560×1440 (1280×1440 per eye) with a refresh rate of 80Hz. For audio, the Rift S includes a headphone jack and near-ear speakers.
The Rift S comes with an inside-out tracking system called Oculus Insight, confirming previous reports. This removes the need to have external cameras for a full-body movement. Oculus Insight will also be included in the company’s upcoming Quest virtual reality headset.
Oculus is also bringing a new feature called Passthrough Plus to the Rift S platform. The feature will enable users to view real-world surroundings as they set up their virtual reality space using the Oculus Guardian tool. Users will be able to switch between the Home Launcher and a real-world feed of their surroundings quickly, thanks to the new inside-out tracking system.
Due to the collaboration, the Oculus Rift S will feature both Oculus and Lenovo branding. It will also ship with a new halo strap. While the company hasn’t specified an exact release date yet, Oculus could launch the Rift S along with the Quest during Facebook’s F8 developer conference which is scheduled for April 30 this year.

At GDC 2019, Google announced Stadia, its game streaming platform. Stadia will work across devices from smartphones, tablets, TVs, laptops, and PCs via Chrome. It integrates YouTube as well, allowing developers to add a Play button to game video on YouTube and lets users immediately play the game on Chrome. Stadia will leverage Google’s data centres that are present in 200 plus countries and territories. Google’s Phil Harrison took to stage to show off Assassin’s Creed Odyssey working across a Chromebook, Pixel 3, and TV via Chromecast in a seamless fashion. Furthermore, you can use your own controllers or keyboard and mouse on Stadia on your PC or laptop.
In addition to this, Google revealed the Stadia controller. It links to data centres directly via WiFi. It features two new buttons — a Capture button that allows players to share to friends, themselves or the world via YouTube. There’s also a Google Assistant button to assist players in-game.
Stadia’s architecture has been built on Google’s data centre tech which also powers its search results. It’s been infused with gaming-focussed hardware to keep up with the task of streaming heavy games. Powering the data centres is the Stadia GPU from AMD which is at 10.7 teraflops. This is nearly double of what the Xbox One X and PS4 Pro has, making it possible to play games like Doom Eternal running at 4K 60fps in HDR on Stadia.
The company claims that it has been testing Stadia’s tech internally for years and plans to allow for 4K 60fps gameplay with HDR in surround sound when it’s available for all. Eventually Stadia will also scale up to 8K too. Users will also be given the option to share Stadia gameplay footage to YouTube at 4K 60fps as well. Developers can create multiple points of purchase and play for games on Stadia through Gmail, YouTube, and search, going as far as to let players click a link on a game trailer and get right into a game. YouTubers could use it to send custom challenges to their fans and players can even create and share their own links to let others get in a game at the exact location they’re in.
However Stadia won’t be restricted to single-player games. Google confirmed that multiplayer games will be supported as well. These would include battle royale and couch-based co-op experiences.
And in a refreshing move, Harrison confirmed that Stadia will support cross-platform play as well. A concrete release date and price point hasn’t been confirmed yet and we don’t know what Internet connection would be needed for it, though Harrison said Stadia will launch in the US, UK, Canada, and Europe later this year.
