News posted 2/12/2009! (megacompilation)

1.I think I talked about the limitation on runing Physx with ATI card for rendering due to Nvidia disabling in 185 and higher..
It's currently artificial limit as seems result of GPU physics sim no stays in GPU..
It's was a mod for 190 WHQL drivers and now new mod for 195 and also adds WinXP support! Both x32,x64..
Remeber no Vista support as no multiple GPUs from multiple vendors allowed in it!
PhysX with ATI GPUs for 195.xx and Win XP added (x32,x64)
Download it! (also a PPU enabler for 30.9.9 drivers present)

2.gpu-z 0.3.8
◦Added sensors to monitor GPU load percentages on NVIDIA

that's goods news..
puts on par with ATI caps..
now if I could check in my code via NVAPI would be perfect..(i suspect..)
Remember ATI I think has the cap via ADL documented altough NVAPI has NDA part..
Checked Directcompute and CUDA demos and seems to work..

3. I put links of both demos of Dirt2 and Avatar games:
Dirt2 link
Avatar link
Note to run the internal benchmark use:
dirt2.exe -benchmark example_benchmark.xml

Also for running Dirt2 with 3D Vision I recommend using this guide:
basically disable shadows and AA and use profile from it..
http://3dvision-blog.com/optimizing-the-game-colin-mcrae-dirt-2/

One thing I note is Dirt2 has Direct3D 11 precompiled shaders compiled with
9.27.952.3022 version of compiler (fxc?) while standard August 2009 SDK has
9.27.952.3012 so this is going to be December/January DirectX SDK?..

Sound in Dirt2
==============

http://en.wikipedia.org/wiki/Ambisonics

Also related altough not graphics related is that I have found that Dirt2 is an OpenAL game and ships with Rapture3D OpenAL of Blue Ripple Sound..
seems a very good implementation with CPU multicore and x64 capable and getting similar perf to X-FI cards on highend cpus.. float32 precision,etc..
Also learned that supports OpenAL EFX extensions with has all of EAX..
Also Rapture3D meets the full OpenAL 1.1 specification, including full support for alSuspendContext() and alProcessContext() to give much better control over scene content than many drivers.

All filters support high-pass as well as low-pass options as documented in the specification.
Rapture3D supports the following OpenAL extensions:

ALC_ENUMERATE_ALL_EXT
ALC_ENUMERATION_EXT
ALC_EXT_CAPTURE
ALC_EXT_DEDICATED (new)
ALC_EXT_EFX
ALC_EXT_STATIC_BUFFER
AL_EXT_BFORMAT (new)
AL_EXT_EXPONENT_DISTANCE
AL_EXT_FLOAT32
AL_EXT_FOLDBACK (new)
AL_EXT_IMA4
AL_EXT_LINEAR_DISTANCE
AL_EXT_MCFORMATS
AL_EXT_MULAW
AL_EXT_MULAW_BFORMAT (new)
AL_EXT_MULAW_MCFORMATS (new)
AL_EXT_OFFSET

Rapture3D supports the EFX interface for effects. The deprecated EAX interfaces are not supported. The following effects are available:

AL_EFFECT_CHORUS
AL_EFFECT_COMPRESSOR
AL_EFFECT_DEDICATED_DIALOGUE (new)
AL_EFFECT_DEDICATED_LOW_FREQUENCY_EFFECT (new)
AL_EFFECT_DISTORTION
AL_EFFECT_EAXREVERB
AL_EFFECT_ECHO
AL_EFFECT_EQUALIZER
AL_EFFECT_FLANGER
AL_EFFECT_REVERB
AL_EFFECT_RING_MODULATOR



4. A library for running Marching Cubes via GPUs using hystopiramids.. it's a GPU computing lib using OpenGL .. (supports 3D Texture and geometry shader imp).. it's actually an old idea (2006-2007 papers).. Both ATI and NVIDIA support..
I think it's also capable of using geometry shader in ATI part (mac win lin)..
I remember seeing faster perf than using geometry shader..
seems to work Windows, Linux and Mac..
Download hpmc library!

5.Qt 4.6 and Qt Creator 1.3 creator released!
I put these news since Qt 4.6 has improvements to OpenGL interop, QTGL..
Qt creat
6. Related is step on running Qt 4.6 on Beagleboard with full OpenGL ES 2.0 support.. go!

7. Also old news and said here but I have to remark that
only recenetly first public opencl nvidia whql drivers are released (195.62) and OpenCL linux public beta ones (195.22)..

8.AMD to launch Mobile Radeon 58x0 at CES 2010.. see fudzilla
I found a laptop note seeing is 1GB cards with GDDR3 :-(
Also 56xx card spotted with GPU-z!
9.Supercomputing 2009 CUDA Tutorial presentations posted! (High Performance Computing with CUDA)

10. WegGL news:
WebGL Demo On the Nokia N900 (a phone with hardware GPU with OpenGL ES 2.0 (power sgx) ):

Interview with Trevett about WebGL seems to suggest possible/future exposure of OpenGL 3.2 functionality!

Also found on mozilla blog:
The WebGL standard goes to Khronos review this week. More public information will be forthcoming once the Khronos board approves it.” It’ll be great to have something more formal in the way of specifications!

I hope specs released in Siggraph Asia 2009!

11. Seems finally I have found both video of SC09 Larrabee and Fermi stuff:

12. Nvidia news:
*A.Today Nvidia release new Quadro mobile gpus supporting Direct3D 10.1 with up to 128 shaders 1Gbyte RAM and with 256bit bus 64Gbytes/s GDDR.. so GT200 based but surely lacking doubles.. support OpenCL, DirectCompute 4.0, OpenGL 3.2 and ·..
A new Dell laptop workstation shipping soon..
*B.Also news of a new app for displaying babies to moms in 3D using Quadro OGL stereo with Samsung 3D Vision monitor!
http://money.cnn.com/news/newsfeeds/articles/marketwire/0563594.htm
*C.NVIDIA RealityServer 3.0 shipping! (CUDA based raytracer by Mental!)
see also interview about MentalRay with CUDA support!
13. Intel new 48 multicore Terascale chip!
Architectural, design and other details of the chip are projected to be revealed at the International Solid State Circuits Conference in February 2010.

Seems 45nm see:
http://software.intel.com/en-us/blogs/2009/12/02/intel-labs-new-research-milestone-in-many-core-computing/

Following and old 80 core chip have 1 Tflop (put links and SC08 paper here..)

14.Huang recopilations of papers of Siggraph were taken down due to ACM restrictions now seem fixed but I think contain link to author pages until conference then ACM link?

15. A GPU Stocasthic Photon Mapping raytracer (using OpenGL) with code avaiable!
It's a Siggraph asia 2009 paper with photon mapping inventor as coauthor:
See:

16.Seems as similar to GPU debugging a lot of apps are coming now also a lot of directive based frameworks (for exploiting Cuda are getting done:

Search for it but I'm aware of:

A)PGI accelerator.
Commercial
lang:Fortran,C
OS:Win,Lin,Mac
API: CUDA, OpenCL(coming)
Has persisten data between kernels..

B)HMPP (2.2)
Commercial
lang:Fortran,C
OS:Win,Lin
API: CUDA, CAL
(and Brook) has persistent data between kernels..
C)HiCUDA
D)CUDAlite

17. Intel Ct stuff in SC09!
