3D-Tech News Around The Web / Ubuntu 15.04 Released, First Version To Feature systemd
« Last post by gyg on April 24, 2015, 03:18:48 PM »
The final release of Ubuntu 15.04 is now available. A modest set of improvements are rolling out with this spring's Ubuntu. While this means the OS can't rival the heavy changelogs of releases past, the adage "don't fix what isn't broken" is clearly one 15.04 plays to. The headline change is systemd being featured first time in a stable Ubuntu release, which replaces the inhouse UpStart init system. The Unity desktop version 7.3 receives a handful of small refinements, most of which aim to either fix bugs or correct earlier missteps (for example, application menus can now be set to be always visible). The Linux version is 3.19.3 further patched by Canonical. As usual, the distro comes with fresh versions of various familiar applications.

NVIDIA's Maxwell GPU architecture has has been well-received in the gaming world, thanks to cards like the GeForce GTX Titan X and the GeForce GTX 980. NVIDIA recently took time to bring that same Maxwell goodness over the workstation market as well and the result is the new Quadro M6000, NVIDIA's new highest-end workstation platform. Like the Titan X, the M6000 is based on the full-fat version of the Maxwell GPU, the G200. Also, like the GeForce GTX Titan X, the Quadro M6000 has 12GB of GDDR5, 3072 GPU cores, 192 texture units (TMUs), and 96 render outputs (ROPs). NVIDIA has said that the M6000 will beat out their previous gen Quadro K6000 in a significant way in pro workstation applications as well as GPGPU or rendering and encoding applications that can be GPU-accelerated. One thing that's changed with the launch of the M6000 is that AMD no longer trades shots with NVIDIA for the top pro graphics performance spot. Last time around, there were some benchmarks that still favored team red. Now, the NVIDIA Quadro M6000 puts up pretty much a clean sweep.

3D-Tech News Around The Web / Qt Creator 3.4.0 Released
« Last post by gyg on April 23, 2015, 07:47:48 PM »
Qt Creator 3.4.0 has been released with many new features. Qt Creator is a C/C++ IDE with specialized tools for developing Qt applications, and it works great for general-purpose projects as well. The new version comes with a C++ refactoring option to move function definitions out of a class declaration, auto-completion for signals and slots in Qt5-style connects, experimental Qt Test and Qt Quick Tests support in the Professional and Enterprise edition, support for 64-bit Android toolchains, and various other improvements.

Data in the Fast Lane: How NVLink Unleashes Application Performance

" ... To avoid “traffic jams” in applications, we invented a fast interconnect between the CPU and GPU, and among GPUs. It’s called NVLink.

It’s the world’s first high-speed interconnect technology for GPUs. NVIDIA NVLink creates a data super-highway in next-gen HPC servers. One that lets GPUs and CPUs exchange data among each other five to 12 times faster than with PCIe."

If you have Windows 10 (technical preview 2) installed, get it from Windows update.
If not get it from here and copy runtime files manually.

3D-Tech News Around The Web / Intel Graphics Performance Analyzers 2015 R1
« Last post by Stefan on April 15, 2015, 08:33:15 PM »
Graphics Performance Analyzers 2015 R1 offers the following new features:

 Features for Analyzing Android* Applications
  • Graphics Frame Analyzer for OpenGL*
     You can now use the brand-new cross-platform Graphics Frame Analyzer for OpenGL* to analyze Android* workloads. This tool supports OpenGL ES* 1.0, 1.1, 2.0, 3.0/3.1 and can be run on Windows*, Ubuntu*, and OS X* host systems. Graphics Frame Analyzer for OpenGL* offers the capabilities for graphics profiling and debugging rendering issues, integrating the functionality of the Graphics Frame Debugger and the legacy Graphics Frame Analyzer. Graphics Frame Debugger is no longer available as a standalone tool.
  • OpenGL ES 3.1 support
     You can now profile OpenGL ES 3.1 graphics applications in Graphics Frame Analyzer for OpenGL, System Analyzer, and Platform Analyzer.
Features for Analyzing Windows* Applications
 
  • Graphics Frame Analyzer for DirectX*
     Graphics Frame Analyzer is now renamed to Graphics Frame Analyzer for DirectX*. This tool no longer supports profiling Android* applications and focuses exclusively on analyzing Windows* applications.

  • Added support for the following GPUs:
    • Quadro K1200
      Quadro M6000
      GeForce 920M
      GeForce 930A
      GeForce 930M
      GeForce 940M
      GeForce GTX 950M
      GeForce GTX 960M
      GeForce GTX TITAN X
  • Added support for G-SYNC monitors when used together with non-G-SYNC monitors.  When G-SYNC is enabled, non-G-SYNC monitors will display with tearing.
  • Fixed a bug that caused nvidia-settings to crash when assigning an attribute whose value is a display ID on a system with multiple X screens.
  • Updated the reporting of in-use video memory in the nvidia-settings control panel to use the same accounting methods used in other tools such as nvidia-smi. nvidia-settings was not taking some allocations into account, e.g. framebuffer memory for the efifb console on UEFI systems, causing discrepancies in the values reported by different tools.
  • Removed the "EnableACPIHotkeys" X configuration option. This option has been deprecated and disabled by default since driver version 346.35. On modern Linux systems, display change hotkey events are delivered to the desktop environment as key press events, and the desktop environment handles the display change by issuing requests through the X Resize and Rotate extension (RandR).
  • Added support for lossless H.264/AVC video streams to VDPAU.
  • Added support for VDPAU Feature Set F to the NVIDIA VDPAU driver. GPUs with VDPAU Feature Set F are capable of hardware-accelerated decoding of H.265/HEVC video streams.
  • Fixed a bug that prevented GPU fan speed changes from getting reflected in the text box on Thermal settings page.
  • Added nvidia-settings commandline support to query the current and targeted GPU fan speed.
  • Added a checkbox to nvidia-settings to enable a visual indicator that shows when G-SYNC is being used.  This is helpful for displays that don't indicate themselves whether they are operating in G-SYNC mode or normal mode. This setting can also be enabled by running the command line
    nvidia-settings -a ShowGSYNCVisualIndicator=1
  • Added support for the X.Org X server's "-background none" option. When enabled, the NVIDIA driver will try to copy the framebuffer console's contents out of /dev/fb0.  If that cannot be done, then the screen is cleared to black.
  • Added support for YUV 4:2:0 compression to enable HDMI 2.0 4K@60Hz modes when either the display or GPU is incapable of driving these modes in RGB 4:4:4.  See NoEdidHDMI2Check in the README for details.
  • Fixed a bug that could cause multi-threaded applications to crash when multiple threads used the EGL driver at the same time.
  • Fixed a bug that caused Sync to VBlank to not work correctly with XVideo applications in certain configurations.
  • Fixed a bug that prevented the X driver from correctly interpreting some X configuration options when a display device name was given with a GPU UUID qualifier.
  • Fixed Pixel Buffer Object operations when row length is less than width. GL_[UN]PACK_ROW_LENGTH can be set to a value lower than the width of the operation being carried out. The OpenGL specification allows for this (the source or destination lines will be overlapping). Previously, our implementation of Pixel Buffer Objects did not support this case and would throw an error.
  • Fixed a bug that caused corruption when switching display modes in some applications that use transform feedback.
  • Fixed a bug that caused texture corruption on framebuffer depth attachments cleared using glClearTexImage().
  • Fixed a bug that artificially limited the maximum pixel clock on displays in some SLI Mosaic configurations.
  • Fixed a kernel memory leak that occurred when looping hardware-accelerated video decoding with VDPAU on Maxwell-based GPUs.
  • Fixed a bug that could cause nvidia-settings to crash on exit on 32-bit Linux systems.
