3D-Tech News Around The Web / NVIDIA GeForce driver 343.22 for Linux, FreeBSD and Solaris
« Last post by Stefan on September 19, 2014, 06:57:08 AM »
  • Added support for the following GPUs:
    • GeForce GTX 970
      GeForce GTX 980
  • Fixed a bug that prevented the "sync to vblank" setting from being honored for EGL applications.
  • Fixed a bug that could cause some OpenGL programs to encounter out of memory during a mode switch.
  • Fixed a bug that prevented the NVIDIA OpenGL driver from honoring the __GL_SHADER_DISK_CACHE_PATH environment variable.
  • Fixed a bug that caused disabled displays to be implicitly included in the target selection for some queries and assignments on the nvidia-settings command line interface, in the absence of any explicit target selection.
  • Added a new attribute to the NV-CONTROL API to query the current utilization of the video decode engine.
  • Fixed a bug where the Exchange Stereo Eyes setting in nvidia-settings didn't work in certain stereo configurations.
  • Worked around a Unigine Heaven 3.0 shader bug which could cause corruption when tessellation is enabled by implementing an application profile that uses the "GLIgnoreGLSLExtReqs" setting.  See the documentation for the __GL_IGNORE_GLSL_EXT_REQS environment variable for more details.
  • Fixed a memory leak when destroying EGL surfaces.
  • Added support for multiple simultaneous EGL displays.
  • Removed support for G8x, G9x, and GT2xx GPUs, and motherboard chipsets based on them. Ongoing support for new Linux kernels and X servers, as well as fixes for critical bugs, will be included in 340.* legacy releases through the end of 2019.

   Cycles Rendering

Volume rendering and Subsurface Scattering are available on GPU, Volume and Glossy sampling was improved, new Ashikhmin-Shirley distribution for Glossy and Anisotropic BSDFs, memory usage during rendering was lowered, OSL updated to version 1.5.
We are happy to announce the availability of our latest and most advanced SDK for OpenCL: Release 2 of Intel® SDK for OpenCL SDK 2014 is the industry’s first SDK to provide an OpenCL 2.0 development environment with the new Intel® Core™ M Processors.
This major advance in graphics programmability and accessibility will help you make greater use of the graphics engine to deliver new experiences on Intel-based platforms
New with SDK 2014 Release 2:
  • OpenCL™ 2.0: Support for latest OpenCL standard version 2.0 with shared virtual memory. Start now and write your first OpenCL 2.0 code on your current development platform, simply by using the new OpenCL 2.0 development environment that is installed with the SDK.
  • Intel® Core™ M Processors: Take advantage of OpenCL 2.0 with the latest Intel® Core™ M processors and future generations of Intel Core processors.
  • SPIR* 1.2: Improve portability and drive innovation with a standard, non-source intermediate representation (IR) for device programs. Supported on both CPU and Intel Graphics.
  • Greater development experience: The SDK provides everything you need to build, debug, and analyze OpenCL application. This release not only adds OpenCL 2.0 and SPIR 1.2 development support, but also adds new preview features for debugging and analyzing applications

3D-Tech News Around The Web / The Compute Architecture of Intel Processor Graphics Gen8
« Last post by JeGX on September 11, 2014, 04:31:30 PM »
Intel® Processor Graphics refers to the technology that provides graphics, compute, media,
and display capabilities for many of Intel’s SoC products. Within Intel, architects colloquially
refer to Intel® Processor Graphics architecture as simply “Gen”, short for Generation. A specific
generation of the Intel® Processor Graphics architecture may be referred to as “Gen6” for
generation 6, or “Gen7” for generation 7, etc. The branded products Intel® HD Graphics 4600,
Intel® Iris™ Graphics 5100, and Intel® Iris™ Pro Graphics 5200 are all derived from instances
of Intel® Processor Graphics Gen7.5 architecture. Intel® HD Graphics 5300 is the first released
product derived from an instance of Intel® Processor Graphics Gen8 architecture. This
whitepaper focuses on just the compute architecture within Intel® Processor Graphics
Gen8. For shorthand, in this paper we may use the term Gen8 compute architecture to refer
to just those compute components. The whitepaper also briefly discusses the instantiation of
Intel® Processor Graphics Gen8 within the recently released Intel® Core™ M Processor for low
power form factors. Additional processor products that include Intel Processor Graphics Gen8
may be released in the near future.

Fluid Simulation for Video Games (part 18)

This article showed how to extract surfaces from a function represented by a grid as a polygon mesh that you can then render. Combined with previous articles in this series, that lets you visualize surfaces of simulated fluids. This article also showed how to parallelize that isosurface extraction routine. Although the routine’s outputs for a given input cell do not appear to depend on those of other cells, there is a subtle dependency on where to write the output. To solve this question, I wrapped the output vertex buffer with a lightweight, thread-safe, linear pool allocator, thereby avoiding race conditions between threads, keeping the vertex buffer usage relatively balanced across threads and the synchronization overhead manageable. You can tune the tradeoff between balancing thread usage of the buffer and synchronization overhead by changing the block size.
