 no change log available, latest was for v4279

When approached a couple of weeks ago by Microsoft with the opportunity to take an early look at an upcoming performance benchmark built on a DX12 game pending release later this year, I of course was excited for the opportunity. Our adventure into the world of DirectX 12 and performance evaluation started with the 3DMark API Overhead Feature Test back in March and was followed by the release of the Ashes of the Singularity performance test in mid-August. Both of these tests were pinpointing one particular aspect of the DX12 API - the ability to improve CPU throughput and efficiency with higher draw call counts and thus enabling higher frame rates on existing GPUs.
This benchmark focuses more on the GPU side of DirectX 12 - on improved rendering techniques and visual quality rather than on the CPU scaling aspects that made Ashes of the Singularity stand out from other graphics tests we have utilized. Fable Legends is more representative of what we expect to see with the release of AAA games using DX12. Let's dive into the test and our results!

Swiss First to Tap GPUs to Improve National Weather Forecasts

... thanks to GPU-accelerated computing, the Swiss have made significant advancements in their ability to predict storms and other weather hazards with higher levels of accuracy.
The Swiss Federal Office of Meteorology and Climatology, MeteoSwiss, is the first major national weather service to deploy a GPU-accelerated supercomputer to improve its daily weather forecasts.
he new MeteoSwiss system is based on the Cray CS-Storm cluster supercomputer, one of the highest density GPU-accelerated systems available today. Expected to be fully operational by next summer, the MeteoSwiss system is housed at the Swiss National Supercomputing Centre in Lugano, Switzerland. It’s powered by NVIDIA Tesla K80 GPU accelerators — the flagship of our Tesla Accelerated Computing Platform.

3D-Tech News Around The Web / NVIDIA CUDA Toolkit 7.5 final release
« on: September 08, 2015, 12:51:35 PM »
 CUDA Toolkit 7.5 

New in CUDA 7.5

 16-bit floating point (FP16) data format
  • Store up to 2x larger datasets in GPU memory
  • Reduce memory bandwidth requirements by up to 2x
  • New mixed precision cublasSgemmEX() routine supports 2x larger matrices
New cuSPARSE GEMVI routines
  • Optimized dense matrix x sparse vector routines - ideal for Natural Language Processing
Instruction-level profiling helps pinpoint performance bottlenecks
  • Quickly identify the specific lines of source code limiting the performance of GPU code
  • Apply advanced performance optimizations more easily
The CUDA Toolkit is now available for all developers.

CUDA 7.5: Pinpoint Performance Problems with Instruction-Level Profiling

...One of the most exciting new features in CUDA 7.5 is new Instruction-Level Profiling support in the NVIDIA Visual Profiler. This powerful new feature, available on Maxwell (GM200) and later GPUs, helps pinpoint performance bottlenecks, letting you quickly identify the specific lines of source code (and assembly instructions) limiting the performance of GPU code, along with the underlying reason for execution stalls.

In this post, I demonstrate Instruction-Level Profiling by showing how it helped understand and improve the performance limitations of a CUDA kernel that implements the Iterative Closest Point algorithm (the original source code, by Thomas Whelan, is available on Github). I’ll show how instruction-level profiling makes it easier to apply advanced optimizations, helping speed up the example kernel by 2.7X on an NVIDIA Quadro M6000 GPU...

The AMD FireRender library is not “just another renderer.” It uses open industry standards to take advantage of both CPU and GPU compute capabilities for ray tracing, and frees you from dependencies on hardware or operating systems.

Not too long ago we released the AMD FireRays Library that accelerates ray tracing and hit testing using OpenCL™. We designed the library to be OS- and hardware-independent. You can read about it here. FireRender takes the same approach.
