Start learning opencl ......
Because old wolf's video card is amd 5xx's redwood, we will first introduce the installation of opencl app (accelerated parallel processing.
Installation notes: http://developer.amd.com/tools/hc/AMDAPPSDK/assets/AMD_APP_SDK_Installation_Notes.pdf
1. opencl Architecture
Opencl can implement parallel computing on hybrid devices, including CPU, GPU, and Other Processors, such as cell processors and DSPs. With opencl programming, you can achieve portable parallel acceleration code. [However, due to the different hardware performance of each opencl device, specific

1. Install the video driver
1) Download the driver in Http://support.amd.com/zh-cn/download/linux, be sure to note the version
2) Install Fglrx-core_15.302-0ubuntu1_amd64_ub_14.01.deb First, you may encounter a lack of libc6-i385 lib32gcc1 dkms, perform

results on AMD and NV platforms are as follows:
Amd gpu = 5870 stream SDK 2.2
Nvidia gpu = GTX 480 with Cuda 3.1
In addition, in the program, we also tried to expand the loop. by expanding the inner loop, we reduced the number of GPU Execution Branch commands. In my test, we used expansion four times, the FPS is 30% faster than that before expansion. (AMD 5670
threads 0, 2, 4 ....
Predicate = false for threads 1, 3, 5 ....
The following is an example of a control flow diverage.
In Case 1, all odd-number threads execute dosomework2 (), and all even-number threads execute dosomeworks. However, in each wave, IF and else Code commands must be released.
In Case 2, the first wave executes IF and the other waves executes else. In this case, only one If and else code is fired in each wave.
In prediction, the command execution time i

First of all, we may have doubts: Since opencl is platform
The amd opencl university course is a very good entry-level opencl tutorial. by reading the PPT In the tutorial, we can quickly learn about the opencl mechanism and programming methods. : Http://developer.amd.com/zones/OpenCLZone/universities/Pages/default.aspx
The English in the tutorial is very simple. I believe that
Since Apple officially submitted its opencl to the khronos group Open Standards Organization in, it has received support from major companies such as AMD, NVIDIA, and Intel. Opencl can make full use of GPU data-intensive large-scale computing capabilities, so that many multimedia applications and even scientific computing can greatly improve performance.

When the SATA mode of the motherboard is set to ahci or raid mode, the hard disk may not be found during installation of the original Windows operating system installation disc.
The original Windows XP installation disc does not contain SATA ahci and raid drivers.Program, Use nlite to integrate the following driver into the XP installation disk. It can solve the problem that the original XP cannot be installed because the ahci cannot be disabled in the cq40 or other notebook boards.
ATI Catalyst 8.6 was released at the end of last month. One month later, AMD released a new version of ATI Catalyst 8.7 for the Linux platform.
This version mainly adds support for Ubuntu 8.04 and SLED 10 sp2 operating systems. At the same time, ATI Catalyst 8.7 also introduced initial support for OpenSuse 11 and Redflag DT 7.0. In addition, some bugs have been fixed in this version.
For more information, see the announcement of ATI Catalyst 8.7.
