Almost out.
http://oscarbg.blogspot.com/2010/07/...k-roadmap.html
There is an OVDecode64.dll inside as promised.

AMD Stream 2.3 SDK release
Performance improvements for AMD’s OpenCL toolset
Support UVD video hardware component through OpenCL driver (Windows 7 only)
Support for the Stream Profiler on Linux (command line version)
Support added for AMD Radeon HD 6800 Series and AMD Radeon HD 6900 Series
Support for FFT and BLAS-3 libraries
Stream Profiler enhancements (including timeline visualization)
Resolves a number of bug fixes from the Stream SDK 2.2 release

[Chabi]

According to the roadmap openphysx SDK is part of the 2.3 would have been, but he can not find any info that was included in.

[Bjorn Häske]

Here is a list of serious unresolved Bugs for OpenCL:
* hd5970 and all other dual-gpu cards: only 1st gpu is supported
* Device query returns wrong Global Memory size
* Device query returns wrong Clock rate
* Linux: multi-gpu is not supported at all
* Linux: each GPU produces 100% CPU load
Btw, none of the above Bugs exists in CAL.
Here is a list of serious missing Features:
* Users manually need to disable crossfirex
* No support for VLIW5 (reduces performance to CAL by 20%)
* No support for bfi_int (reduces performance to CAL by 15%)
* Windows: Requires a monitor connected to card for each GPU
* Linux: Requires a valid Xsession of the User who is running the OpenCL app
* Linux: Users still need to install the whole SDK just to get libOpenCL.so

There's no such thing, let's not rape yet another term on the whims of marketing (I'm pretty sure the font in that slide is large enough to make the odds of an unintentional mistake on your part quite low). I doubt Newton would manage to hold posture in his coffin if he was called a physxist.

are at http://developer.amd.com/gpu/ATIStre...mentation.aspx

Some of the links that says 2.2 have 2.3 documents.

Biggest disappointment for me is that they still have not implemented cl_khr_fp64 (see the FAQ) only a subset via cl_amd_fp64.

Until the programming guide is updated there is no information on 69xx support or what has changed with cl_amd_fp64. Hopefully all the double precision function are no longer marked beta.

I'm not sure if this is news, but the Stream Kernel Analyzer (1.7) produces code and statistics for the 6970

That's true, Newton was a natural philosxpher

So, it's officially out: http://developer.amd.com/gpu/ATIStre...s/default.aspx

What’s New in ATI Stream SDK 2.3

* Improved OpenCL runtime performance:
o Improved kernel launch times.
o Improved PCIe transfer times.
o Enabled DRMDMA for Evergreen GPUs, as well as AMD Radeon™ HD 6870 and AMD Radeon™ HD 6850 devices.

* Increased size of staging buffers.
* Enhanced Binary Image Format (BIF).
* Support for UVD video hardware component through OpenCL (Windows 7).
* Support for Northern Islands family of devices.
* Support for AMD Radeon™ HD 6310 and AMD Radeon™ 6250 devices.
* Support for OpenCL math libraries: FFT and BLAS-3, available for download at AMD Accelerated Parallel Processing Math Libraries.
* Preview feature: An optimization pragma for unrolling loops.
* Preview feature: Support for CPU/X86 image. This enables the support for Image formats, as described in the Khronos specification for OpenCL, to be run on the x86 CPU. It is enabled by the following environment variable in your application: CPU_IMAGE_SUPPORT.
* ATI Stream Profiler 2.1 enhancements:
o Timeline visualization and API Trace.
o Support for 64-bit profiling.
o Support for Linux (command line version).
o Support for profiling DirectCompute applications.

* Stream KernelAnalyzer (SKA) 1.7 enhancements:
o Support for Northern Islands devices.
o Support for Catalyst 10.9 to 10.12.

* New samples:
o MonteCarloAsianDP
o DeviceFission
o FluidSimulation2D

* Optimized Histogram sample.
* Added makefiles and implemented changes in samples code to compile with Intel compiler, MinGW + GCC, and MinGWx64 + GCC.
* Various OpenCL™ compiler and runtime fixes and enhancements (see developer release notes for more details).
* Various samples fixes and enhancements (see samples release notes for more details).

Good News!!!!!!
 
 Today some guy posted on AMD dev forum about an undocumented environment variable "GPU_USE_SYNC_OBJECTS": here
 
 Setting this environment variable to 1 solves the three most annoying problems at once:
 
 1. hd5970 2nd gpu works (have not tested 2x hd5970 yet, have not tested on windows)
 2. multi gpu on linux works
 3. CPU usage is at 0%.

2.5 SDK is out. Still no zero copy for linux.

Bad AMD. Very BAD.

But finally Doubles, but only for Cypress yet. And AVX on CPUs.
