ATI Catalyst™ 10.6 Driver – What’s New?

Compared to 10.6 beta a profile for empires.exe has been added

KitGuru knows that companies spend millions creating the best HD processing set up possible only to see the final image quality shattered by a weak component somewhere in the system.
We spend many hours watching High Definition content and we never stop playing with our ATI and nVidia driver panels to get the quality as high as we can.
All this fiddling might be fun, but can we add any science to the process of deciding on the best picture? HQV Benchmark 2.0 aims to do just that.

Robert Hess has a roundtable discussion with industry experts to help you understand exactly what DirectCompute is and the kinds of software problems that you can apply DirectCompute to leaverage the GPU for computation.

Changes include:

    * Reference Results: changed UI from multiple combo-boxes to single list-view, making it easier to select, view and modify reference results. You can still only select 4 devices for now, with the earliest unselected if you check more than 4.
    * AVX instruction set: extensive support in all benchmarks: Multi-Media (integer & float), Memory Bandwidth (integer & float, buffered and unbuffered/streaming), Cache & Memory (non-streaming). Removed EMMX.
    * OpenCL: unified module supporting all manufacturer versions (ATI, nVidia, etc.), can use multiple cards from multiple vendors in parallel.
    * OpenGL: now supports versions 4.0 and 3.3; ARB native double support on ATI 5800 and nVidia Fermi (previously only ATI specific doubles were supported).
    * Ranking Engine: is now on-line and localised in all the languages Sandra supports.

3D-Tech News Around The Web / GLSL Minifier

GLSL Minifier is a tool to pack GLSL shader code. It generates a code as small as possible that is equivalent to the input code. The generated code is also designed to compress well. It has been optimized for use with Crinkler, but should perform well with any other compression tool. GLSL Minifier generates a C header file you can include from your code. This file contains the shader code in a compact string and macros to retrieve the name of the uniforms (because they are renamed).

The DirectX SDK (June 2010) release includes the fixes to the DDSWithoutD3DX and DDSWithoutD3DX11 samples I mentioned in earlier posts. The Programmer's Guide for DDS in the Windows DirectX Graphics documentation was also updated to reflect the latest format details.

There is a footnote at the end of the documentation chart that I wanted to expand on, and this is a consequence of D3DX having a long-standing bug in the way it reads and writes 10:10:10:2 format DDS data files.

The Vienna Computing Library (ViennaCL) is a scientific computing library written in C++ and based on OpenCL. It allows simple, high-level access to the vast computing resources available on parallel architectures such as GPUs and is primarily focused on common linear algebra operations (BLAS level 1 and 2) and the solution of large systems of equations by means of iterative methods. The following iterative solvers are implemented:

    * Conjugate Gradient (CG)
    * Stabilized BiConjugate Gradient (BiCGStab)
    * Generalized Minimum Residual (GMRES)

An optional ILU preconditioner can be used, which is at present computed on the CPU and may thus not lead to overall performance gains.

The library interface is similar to that of the ublas library, which is shipped with Boost. The iterative solvers can be used either on the CPU with ublas types or on the GPU using ViennaCL types.

More information can be found on the project homepage located at http://viennacl.sourceforge.net.

No challenge for contemporary GPUs, but nice to watch.

PhysX System Software is the same as the one day older beta version, except from being digitally signed at May 28th and messed up time stamps in "common" folder.

3D-Tech News Around The Web / OpenCL 1.1 specifications
« on: June 15, 2010, 12:48:00 AM »
OpenCL 1.1 includes significant new functionality including::

    * Host-thread safety, enabling OpenCL commands to be enqueued from multiple host threads;
    * Sub-buffer objects to distribute regions of a buffer across multiple OpenCL devices;
    * User events to enable enqueued OpenCL commands to wait on external events;
    * Event callbacks that can be used to enqueue new OpenCL commands based on event state changes in a non-blocking manner;
    * 3-component vector data types;
    * Global work-offset which enable kernels to operate on different portions of the NDRange;
    * Memory object destructor callback;
    * Read, write and copy a 1D, 2D or 3D rectangular region of a buffer object;
    * Mirrored repeat addressing mode and additional image formats;
    * New OpenCL C built-in functions such as integer clamp, shuffle and asynchronous strided copies;
    * Improved OpenGL interoperability through efficient sharing of images and buffers by linking OpenCL event objects to OpenGL fence sync objects;
    * Optional features in OpenCL 1.0 have been bought into core OpenCL 1.1 including: writes to a pointer of bytes or shorts from a kernel, and conversion of atomics to 32-bit integers in local or global memory.

The OpenCL 1.1 specification and header files are available in the Khronos Registry
The OpenCL 1.1 Quick Reference card.
The OpenCL 1.1 Online Man pages.

This beautiful abbey pack is based on a real abbey based in England, of which optimum care has been taken to reproduce the still standing structures that exist today. The pack is a faithful recreation of the site. Before the pack was produced, a trip was taken to the abbey, of which hundreds of pictures where taken, to carefully recreate the buildings and maintain total authenticity. All pack pieces come as separate elements, so you can actually design your own abbey scenario.

3D-Tech News Around The Web / The GPU Computing Era
« on: June 12, 2010, 08:39:42 AM »
As we enter the era of GPU computing, demanding applications with substantial parallelism increasingly use the massively parallel computing capabilities of GPUs to achieve superior performance and efficiency. Today GPU computing enables applications that we previously thought infeasible because of long execution times.
