The DHS Issues Medical Advisory for Medtronic Cardiac Devices

The Department of Homeland Security (DHS) has issued a cybersecurity warning that documents vulnerabilities in the Medtronic Conexus Radio Frequency Telemetry Protocol. Medtronic makes cardio-defibrillators that are planted into a patient's chest and can be read and programmed by trained medical personnel. This allows the devices to communicate with home monitoring devices and Carelink programmers found at doctor's offices. These vulnerabilities require a low level of skill to exploit as the proprietary Conexus telemetry protocol utilized within this ecosystem does not implement authentication or authorization. An attacker can inject, replay, modify, and/or intercept data within the telemetry communication. This communication protocol provides the ability to read and write memory values to affected implanted cardiac devices; therefore, an attacker could exploit this communication protocol to change memory in the implanted cardiac device. Because the devices also lack encryption, attackers can listen to communications, including the transmission of sensitive data. Medtronics is working on developing updates to fix the vulnerabilities.

"It is possible with this attack to cause harm to a patient, either by erasing the firmware that is giving necessary therapy to the patient's heart, or by directly invoking shock related commands on the defibrillator," he said. "Since this protocol is unauthenticated, the ICD cannot discern if communications its receiving are coming from a trusted Medtronic device, or an attacker." A successful attacker could erase or reprogram the defibrillator's firmware, and run any command on the device.

Steam Is Getting a Redesigned Library and New Events Features

At GDC today, Valve announced a new UI for the Steam Library. The new Steam Library has larger game icons and more categorization for your games. PC Gamer says the library reminds them of Plex or the Apple TV. The Steam Friend's List is integrated into the Library view on the right side. They noted that the coolest feature is using Steam Tags for games to create new categories such as "Ninja Action." A Beta release is scheduled for this summer. The new Steam Events page will create a new way for fans of games to connect with developers. Games in your library that are organizing occasions like game updates, streams, tournaments, and so on will be found here. This is being built in response to today's live service games. Developers will be able to get the word out to fans through calendar support for Google and iCal, Steam client notifications, email, text message, and Steam mobile app. These events will be shown in other parts of Steam also.

"We think of this as the way developers will be able to communicate with players through Steam," Kroll said. "We want to build the foundation for a communication platform where all the interesting things that are happening in games can find their way to the customers. And the customers that are interested in finding out 'what's happening in games in my library, what kind of events are happening, what's been updated recently, what are my friends doing,' making all that much easier for players to be able to find."

Google Fined $1.7 Billion Over Monopolistic Practices

The European commission has reportedly slapped Google with a 1.49 billion Euro (or $1.69 billion USD) fine for "abusing its monopoly in online advertising." More specifically, the report alleges that Google prevented companies that using its search service from running any third party adverts, and the commission claims that "Google's rivals were not able to compete on the merits, either because there was an outright prohibition for them to appear on publisher websites or because Google reserved for itself by far the most valuable commercial space on those websites, while at the same time controlling how rival search adverts could appear." Google apparently changed these practices in 2016, but it took some time for the repercussions to catch up with them.

Margrethe Vestager, the EU's competition commissioner, said: "Google has cemented its dominance in online search adverts and shielded itself from competitive pressure by imposing anti-competitive contractual restrictions on third-party websites. This is illegal under EU antitrust rules. The misconduct lasted over 10 years and denied other companies the possibility to compete on the merits and to innovate - and consumers the benefits of competition."

Digital Foundry Analyzes Google's Stadia Platform

Following Google's "Stadia" game streaming service announcement yesterday, Digital Foundry decided to take a closer look at the hardware behind the platform. Google says they use a "Custom 2.7GHz hyper-threaded x86 CPU with AVX2 SIMD and 9.5MB L2+L3 cache," and while they didn't mention the vendor, DF notes that they haven't seen such a configuration in any of AMD's currently shipping server CPUs, and that it should significantly outpace anything found in a modern console. Meanwhile, the GPU largely resembles a Vega 56 card with 16GB of HBM2, and the games are reportedly loaded from an SSD. Through their own testing, DF came away impressed with the platform's consistent frame pacing, and in some cases, total latency is on par with locally-run games on a console or PC.

Google has also demonstrated scalability on the graphics side, with a demonstration of three of the AMD GPUs running in concert. Its stated aim is to remove as many of the limiting factors impacting game-makers as possible, and with that in mind, the option is there for developers to scale projects across multiple cloud units: "The way that we describe what we are is a new generation because it's purpose-built for the 21st century," says Google's Phil Harrison. "It does not have any of the hallmarks of a legacy system. It is not a discrete device in the cloud. It is an elastic compute in the cloud and that allows developers to use an unprecedented amount of compute in support of their games, both on CPU and GPU, but also particularly around multiplayer."

Google Partners with AMD for Google Stadia Game Streaming Service

Google has selected AMD as its partner for the Google Stadia game streaming service. Google will use high-performance, custom AMD Radeon datacenter GPUs for its Vulkan and Linux-based Google Stadia. AMD noted how its commitment to open-source AMD Linux drivers would allow Google and its development partners to inspect the code and understand exactly how the driver works, enabling them to better optimize their applications to interface with AMD Radeon GPUs. AMD supplies other tools such as the AMD Radeon GPU Profiler (RGP) that allows developers to identify timing issues that might lead to optimizations. The Google Stadia service will feature game streams with resolutions up to 4K HDR 60 FPS. Google announced a 2019 launch time for the game streaming service.

Streaming graphics-rich games to millions of users on demand and from the cloud requires ultra high-performance processing capabilities to minimize latency and maximize game performance. It also requires advanced technologies to tackle unique datacenter challenges, including security, manageability, and scalability. The AMD graphics architecture supports a wide range of today's gaming platforms -- from PCs to major game consoles -- enabling developers to optimize their games for a single GPU architecture and extend these benefits across multiple platforms which now include large-scale cloud gaming platforms.

All Myspace Data Before 2016 is Gone

Thanks to a "faulty server migration," MySpace has lost all data uploaded to the site before 2016. MySpace users started noticing the problem over a year ago, but tech support staff only recently started acknowledging that users' data may never come back. The Guardian claims "50m tracks from 14 million artists have been lost," and according to one of their articles from last year, the site still has many dedicated users.

Some have questioned how the embattled company, which was purchased by Time Inc in 2016, could make such a blunder. "I'm deeply sceptical this was an accident," wrote the web expert Andy Baio. "Flagrant incompetence may be bad PR, but it still sounds better than, 'We can't be bothered with the effort and cost of migrating and hosting 50m old MP3s.'" Myspace initially claimed the deletion was a temporary error, with customer support staff telling one user: "I have been informed the issue will be fixed." But by July last year it was publicly acknowledging that no such fix was forthcoming.

Real-Time Ray Tracing Support Comes to GeForce GTX GPUs and Game Engines

NVIDIA has announced that real-time ray tracing support is coming to GeForce GTX GPUs. This driver is scheduled to launch in April. GeForce GTX GPUs will execute ray traced effects on shader cores and support is extended to both Microsoft DXR and Vulkan APIs. NVIDIA reminds consumers that its GeForce RTX lineup of cards has dedicated ray tracing cores built directly into the GPU which deliver the ultimate ray tracing experience. GeForce RTX GPUs provide up to 2-3x faster ray tracing performance with a more visually immersive gaming environment than GPUs without dedicated ray tracing cores. NVIDIA GameWorks RTX is a comprehensive set of tools and rendering techniques that help game developers add ray tracing to games. Unreal Engine and Unity have announced that integrated real-time ray tracing support is being built into their engines.

Real-time ray tracing support from other first-party AAA game engines includes DICE/EA's Frostbite Engine, Remedy Entertainment's Northlight Engine and engines from Crystal Dynamics, Kingsoft, Netease and others. Quake II RTX -- uses ray tracing for all of the lighting in the game in a unified lighting algorithm called path tracing. The classic Quake II game was modified in the open source community to support ray tracing and NVIDIA's engineering team further enhanced it with improved graphics and physics. Quake II RTX is the first ray-traced game using NVIDIA VKRay, a Vulkan extension that allows any developer using Vulkan to add ray-traced effects to their games.

Microsoft Announces Variable Rate Shading Support for DX12

Variable Rate Shading (VRS) is a powerful new API that gives the developers the ability to use GPUs more intelligently. Shaders are used to calculate the color of each pixel in a screen. Shading rate refers to the resolution at which these shaders are called (which is different from the overall screen resolution). A higher shading rate means better visual fidelity at the cost of using more GPU power. All pixels in a frame are affected by the game's shading rate. VSR allows developers to choose which areas of the frame are more important and increase the visual fidelity, or set parts of the frame to have lower fidelity and gain extra performance. Lowering the fidelity of parts of the scene can help low spec machines to run faster. There are two tiers of support for VRS. First of all the VRS API lets developers set the shading rate in 3 different ways: per draw, within a draw by using a screenspace image, or within a draw, per primitive. The hardware that can support per-draw VRS hardware are Tier 1. There's also a Tier 2, the hardware that can support both per-draw and within-draw variable rate shading. VRS support exists today on in-market NVIDIA hardware and on upcoming Intel hardware. AMD is rumored to be working on support for the feature.

For example, foveated rendering, rendering the most detail in the area where the user is paying attention, and gradually decreasing the shading rate outside this area to save on performance. In a first-person shooter, the user is likely paying most attention to their crosshairs, and not much attention to the far edges of the screen, making FPS games an ideal candidate for this technique. Another use case for a screenspace image is using an edge detection filter to determine the areas that need a higher shading rate, since edges are where aliasing happens. Once the locations of the edges are known, a developer can set the screenspace image based on that, shading the areas where the edges are with high detail, and reducing the shading rate in other areas of the screen.

Intel Delivers First Exascale Supercomputer to Argonne National Laboratory

Intel Corporation and Cray Inc. have announced that a Cray "Shasta" system will be the first U.S. exascale supercomputer. This $500 million Aurora supercomputer will be coming to the U.S. Department of Energy's Argonne National Laboratory in 2021 and will have a performance of one exaFLOP - a quintillion floating point operations per second. In addition, this system is designed to enable the convergence of traditional HPC, data analytics, and artificial intelligence -- at exascale. The program contract is valued at more than $100 million for Cray, one of the largest contracts in the company's history. The design of the Aurora system calls for 200 Shasta cabinets, Cray's software stack optimized for Intel architectures, Cray Slingshot interconnect, as well as next generation Intel technology innovations in compute processor, memory and storage technologies. Intel's Rajeeb Hazra detailed some of the futuristic technology coming to Aurora including a future generation Intel Xeon Scalable processor, the recently announced Intel Xe compute architecture, and Intel Optane DC persistent memory. "Today is an important day not only for the team of technologists and scientists who have come together to build our first exascale computer -- but also for all of us who are committed to American innovation and manufacturing," said Bob Swan, Intel CEO. "The convergence of AI and high-performance computing is an enormous opportunity to address some of the world's biggest challenges and an important catalyst for economic opportunity."

The Aurora system's exaFLOP of performance -- equal to a "quintillion" floating point computations per second -- combined with an ability to handle both traditional high-performance computing (HPC) and artificial intelligence (AI) will give researchers an unprecedented set of tools to address scientific problems at exascale. These breakthrough research projects range from developing extreme-scale cosmological simulations, discovering new approaches for drug response prediction and discovering materials for the creation of more efficient organic solar cells. The Aurora system will foster new scientific innovation and usher in new technological capabilities, furthering the United States' scientific leadership position globally.
