This guide provides configuration, optimization, and tuning information and recommendations for AMD Opteron™ 
6200 Series processors (formerly code-named “Interlagos” and built on AMD’s new core architecture) running   
in a Linux environment. This guide is designed to help users through initial bios and system setup to ensure that   
a base level of performance is achieved. Once a system is configured to this level, users can reference AMD’s   
Software Optimization Guide for AMD Family 15h Processors to help further optimize workload performance.

3D-Tech News Around The Web / NVIDIA CUDA 4.2 RC1 with GTX680 support
« on: April 18, 2012, 05:15:00 PM »
A bit late this news, but NVIDA announced it nowhere except from the thread in their new unreadable forum  ::)

Actually i was puzzled the other day about the Macintosh driver.

Where do I get CUDA toolkits for GeForce GTX 680?

The recommended CUDA Toolkit can be downloaded from:

Windows Users (GTX 680 only at this time):

The recommended NVIDIA Driver for GTX 680 is 301.10, which can be downloaded from

Linderdaum Puzzle released with 3D flow UI

Apr 10, 2012

Linderdaum released next major version of its in-development Android game Linderdaum Puzzle. The game uses Linderdaum Engine to render smooth GUI with 3D images gallery. Linderdaum Puzzle runs on Android 2.1+ smart-phones and tablets via OpenGL ES 2.0 and is available from Google Play. Source code of the game is available within Linderdaum Engine SDK. Linderdaum Engine is an open source purely object-oriented 3D gaming engine for Microsoft Windows and Google Android written in C++. It is designed to be an integrated solution for the development of interactive 3D applications, for game, industrial and scientific visualization.

The app is now also available at, good for devices without Gapps  :)

Quote from:
GIMP 2.8 RC 1 arrives with GPU acceleration

The GIMP developers have announced the first release candidate for the upcoming 2.8 stable release of the open source graphics package. The new version includes updates to the Generic Graphics Library (GEGL) and the beginnings of support for GPU hardware acceleration using OpenCL.

Security vulnerability CVE-2012-0946 in the NVIDIA UNIX driver was disclosed to NVIDIA on March 20th, 2012. The vulnerability makes it possible for an attacker who has read and write access to the GPU device nodes to reconfigure GPUs to gain access to arbitrary system memory. NVIDIA is not aware of any reports of this vulnerability, outside of the disclosure which was made privately to NVIDIA.

The default file permissions on the GPU device nodes grant read and write access to all users. The permissions are configurable, but even on systems where the device node permissions are restricted, read and write access must be granted to any users who need to run applications that perform GLX direct rendering, or use the GPU to run computations through APIs like CUDA or OpenCL. Because any user with read and write access to the GPU device nodes could potentially exploit this vulnerability to gain access to system memory that would normally be inaccessible to that user, this vulnerability has been classified as high risk by NVIDIA.

NVIDIA has identified the root cause of the vulnerability and has released updated drivers which close it. The 295.40 driver for Linux, Solaris, and FreeBSD contains the fix for this issue, and we encourage all users with Geforce 8 or newer, G80 Quadro or newer, and all Tesla GPUs to update their drivers to one of these versions. Additionally, a patch to the kernel interface layer of the NVIDIA Linux kernel module is available, which can be used to patch older drivers, if necessary. The patch and instructions on how to apply it are available at Driver 295.40 already has the patch applied: if it is installed, then no further action is necessary.

The Linux CUDA debugger will no longer work after applying the security patch. An updated CUDA library is required in order to use the CUDA debugger with a driver which has had this vulnerability closed. The CUDA library distributed with 295.40 contains the changes necessary for proper operation of the CUDA debugger.

NVIDIA provides a technical contact to security firms to inform us of potential security issues. We encourage anyone that has identified what they believe to be a security issue with an NVIDIA driver to directly contact our UNIX Graphics Driver security email alias,, to report and evaluate any potential issues prior to publishing a public security advisory.

NVIDIA is committed to providing robust, secure graphics drivers for Linux, Solaris, and FreeBSD. We encourage anyone encountering issues with our driver to work with us through the forums to help us collect the information needed to investigate and resolve issues in our driver.

We look forward to continuing to work with the professional security community to make our driver more robust and secure.

3D-Tech News Around The Web / Android SDK R18 (OS 4.04) released

A Faster Emulator with Better Hardware Support

Added GPU Support

The system image we’re shipping today has built-in GPU support (Android 4.0.3 r2). With Android’s growing reliance on using the GPU to improve performance, the difference is significant. In the video below, the emulator is still interpreting ARM instructions; the performance boost is the effect of putting the GPU to work.

As a bonus, since we’re now supporting OpenGL ES 2.0, your OpenGL games can now run inside the emulator.

Please note that there are a lot of GPUs out there, and we haven’t tested all of them for this beta release, so let us know if you have feedback or encounter issues.

Attention: snapshot and GPU emulation still exclude each other.

If you get it running w/o crash, it looks like this in Android GPU tools:
