GPUs Help Measure Rising Sea Levels in Real-Time

GPUs Help Measure Rising Sea Levels in Real-Time

Sea levels have traditionally been measured by marks on land – but the problem with this approach is that parts of the earth’s crust move too.

A group of researchers from Chalmers University of Technology in Sweden are using GPS receivers along the coastline in combination with reflections of GPS signals that bounce off the water’s surface. NVIDIA GPUs then crunch those data signals to compute the water level in real-time.

The researchers are using the cuFFT library, alongside NVIDIA Tesla and GeForce GPUs to process the nearly 800 megabits per second of data that come from the reflectometry stream systems.

Schematics of the data flow for a software-defined radio GNSS-R solution. Direct (RHCP) and reflected (LHCP) signals are received, A/D converted and sent to a host PC, where a Tesla K40 GPU handles signal processing.

“Without the use of GPUs, we would not have been able to process all our signals in real-time,” said Thomas Hobiger, a researcher on the project.

This work has placed the team among the top five finalists for NVIDIA’s 2016 Global Impact Award which awards a $150,000 grant to researchers doing groundbreaking work that addresses social, humanitarian and environmental problems.

GeForce GTX 980 Notebooks a VR Developer’s Dream

Virtual reality takes immense amounts of computing horsepower. Creating VR content takes even more graphics grunt. No surprise, then, that content creators have been asking us for VR-ready performance in a notebook.

Today they’re getting it. That’s thanks to a spate of new notebooks equipped with the power of our GeForce GTX 980 GPU.

That’s no typo. These notebooks use the same 2,048-core GM204 GPU found in our GeForce GTX 980 graphics cards. They’re equipped with GDDR5 memory, fast CPUs, multiple USB 3.0 ports and direct HDMI out, making them the world’s first notebooks to meet (and exceed) the recommended spec for Oculus Rift.

Run Unreal Engine 4? Not a problem. “The GTX 980 notebook includes a fully loaded GTX 980 GPU in a laptop form factor. It’s a great platform for utilizing Unreal Engine 4’s high-end features, such as physically based shading, DirectX 12 and virtual reality device support,” says Tim Sweeney, founder and CEO of Epic Games.

Power demanding VR games? Without breaking a sweat. “The GeForce GTX 980 notebook is a very impressive piece of hardware. EVE: Valkyrie runs super smooth on it with rock-solid performance,” says Owen O’Brien, executive producer, EVE: Valkyrie, CCP Games.

These machines are designed for heavy-duty gaming and game development. Both the CPU and GPU are overclockable. Many are equipped with G-SYNC display technology for stutter-free, tear-free frame delivery. And those are just the highlights.

Whether a developer is showcasing a new VR demo at an event or creating the next killer VR app, GeForce GTX 980 notebooks can deliver on the go. Borrowing a rig or safely packing one up to hit the road is now a thing of the past.

The first GeForce GTX 980-equipped notebooks will be available in October. The full list of OEMs include: MSI, Aorus, ASUS, Clevo, Origin PC, Maingear, Falcon NW, Digital Storm , Sager, XMG, PC Specialist, LDLC, Hyperbook, G-Tune, AfterShock, BossMonster, Metabox and Terransforce.

GameWorks VR SDK Update

To coincide with the release of this new hardware, our GameWorks VR SDK gets an update with the following features:

  • GeForce GTX notebook support
  • VR SLI enhancements when using Direct Mode
  • Expanded head-mount display supported
  • Bug fixes and stability improvements

Download our latest display driver to get the GameWorks VR updates. Stay tuned for more VR news at Oculus Connect later this week!
