With the introduction of OpenCL™ 1.1 support, I wanted to take a moment to address a concern some developers have expressed about OpenCL™. The developers I talk to love the fact that OpenCL™ is an open, cross-platform standard and that its evolution is not dictated by a single company. In fact, if you look at the OpenCL™ 1.1 announcement  issued by Khronos, there are almost 30 companies and institutions listed, ranging from hardware and tool vendors to national laboratories.

The concern, or rather misconception, is that as an open standard OpenCL™ is slow to evolve and difficult to extend. Thankfully the Khronos OpenCL™ working group provided for a tiered extension mechanism, making OpenCL™ a nimble and extendable open standard.

3D-Tech News Around The Web / ARM Mali GPU Device Driver open source
« on: August 12, 2010, 07:19:09 PM »
Recently we released a major update to the Linux drivers for the Mali-200 and Mali-400 MP  GPUs. Like many software projects we time-box our driver development, with two major releases each year. This release (r2p0) contains a bunch of exciting new features including Android  support, full SMP support, performance optimizations and some important EGL extensions. We'll talk about some of these in future blog posts, but for today I wanted to tell you about the other big change we made for r2p0: we've started to release parts of the driver stack under an open source license.

3D-Tech News Around The Web / MSI Afterburner 2.0.0 Beta 6
« on: August 12, 2010, 03:57:47 PM »
Download Afterburner 2.0.0 Beta 6 from Guru3D
Archive also contains Kombustor 1.1.3

Revision history:


Version 2.0.0

- Voltage control layer has been seriously revamped to give additional freedom
  to extreme overclockers with new custom design MSI graphics cards. Now MSI
  Afterburner is able to control up to 3 voltages on custom design MSI Fermi
  and other future custom design MSI graphics cards. New adjustable voltages
  include memory voltage and special multi-purpose auxiliary voltage feeding
  either memory bus (also known as VDDCI on AMD graphics cards) or PCIE bus
  and crystal (PEXVDD on NVIDIA graphics cards)
- Added core, memory and auxiliary PEXVDD voltage control for custom design MSI
  N480GTX Lighning series graphics cards with uP6225+uP6262 voltage regulators
- Added core, memory and auxiliary PEXVDD voltage control for custom design MSI
  N470GTX Twin Frozr II OV3 series graphics cards with uP6218+uP6262 voltage
- Added core, memory and auxiliary PEXVDD voltage control for custom design MSI
  MSI N460GTX Hawk series graphics cards with uP6262 voltage regulators
- Added core voltage control for custom design MSI N460GTX Cyclone series
  graphics cards
- Added auxiliary VDDCI voltage control for reference design AMD RADEON HD 5870
  series graphics cards
- Added fan tachometer monitoring for NVIDIA graphics cards. Please take a note
  that not all graphics cards are tachometer reading capable. So depending on
  graphics card and cooling system fan tachometer monitoring can be unavailable
- Optimized NVIDIA driver-level clock frequency monitoring codepath
- Minimum clock limits for all graphics cards have been reduced from 75% to 50%
- Dynamic overclocking, voltage and fan speed limits. MSI Afterburner no longer
  uses static slider limits calibration and adjusts the limits dynamically when
  some external factors affect it (e.g. Overdrive clock limits on AMD cards or
  VGA BIOS fan speed and voltage limits on NVIDIA GeForce GTX 400 cards)
- New temperature hysteresis settings for software automatic fan control mode
  gives you additional way to improve cooling system thermal and acoustic
- Now fan speed limits (i.e. minimum and maximum fan speeds accepted by VGA
  BIOS and display driver) are displayed in custom fan speed curve editor
- Built-in skin sizes have been reduced due to optimized internal skin panels
  representation and optimized compiled bitmap cache
- Optional skin compression ability in the built-in skin compiler. Skin format
  reference documentation has been updated to document new compression options
- Minor built-in skins appearance tweaks
- Now MSI Afterburner uses previously undocumented power user oriented startup
  mode via the task scheduler under Windows Vista / Windows 7. MSI Afterburner
  launch no longer requires UAC confirmation at Windows startup. Please take a
  note that Microsoft Visual C++ 2008 runtime libraries must be installed to
  get new startup mode working
- Now MSI Afterburner automatically fixes startup link if <Start with Windows>
  or <Apply overclocking at system startup> is enabled but the registry or task
  scheduler startup entry is missing
- Startup profile is now displayed in <Apply at Windows startup> option floating
  tooltip instead of the main window
- Now power users can enable optional DirectInput based hotkeys handler via the
  configuration file. DirectInput based hotkeys processing can seriously reduce
  hotkey response time in the applications heavily loading CPU (mostly 3D games)
  and leaving not enough time for processing standard keyboard input message
  queues. Please take a note that enabling such sophisticated hotkeys handling
  mode can cause some system security applications (e.g. pro-active application
  behavior analysis module of KIS) to warn you about possible keylogging threat
- Improved skin engine, now skinned controls support horizontal and/or vertical
  centering. Skin format reference guide has been updated to document these new
  alignment modes
- MSI On-Screen Display server has been upgraded to version 3.7.2. New version
  gives you the following improvements:
  - Now screen capture events are identified visually by text message flashing
    in On-Screen Display during 0.25s
  - Built-in skin sizes have been reduced due to optimized compiled bitmap cache
  - Added On-Screen Display profile for Startcraft II : Wings of Liberty
- Added configuration file switch allowing sending MSI Afterburner to system
  tray instead of closing on <Close> button click
- <Start the task only when computer is running on AC power> option is no longer
  set in the startup task settings to allow automatically starting application
  via the task scheduler on laptops or on some UPS models
- Added Korean localization

This quick start guide is designed to assist a new user in setting up and starting PerfHUD ES profiling. PerfHUD ES enables experimentation and in-depth analysis of OpenGL ES applications. Through data provided by the OpenGL ES driver and the NVIDIA GPU, developers are given access to GPU performance and bottleneck information in order to target optimizations where they are most needed. The debugging capabilities give full access to the state of the OpenGL ES pipeline, related textures and shaders, and all rendering states to help find the causes for improper setup and rendering anomalies.

For detailed information on the use of PerfHUD ES please refer to the PerfHUD ES User Guide that is installed with the host application.

The trick in the previous post is as implied by its title and noted in the comments not going to give much return on the time invested in terms of performance, although it might give you a deeper understanding of the underlying mechanisms and costs involved in calling virtual functions. So it's more like an academic exercise, but nonetheless a cool thing to play around with.
