Abstract:Which type of algorithm is faster when the accelerator and opencl are used? Professor Wu Feng from the Virginia University of Technology and his team gave an example of an algorithm list, sharing 13 typical cases that opencl is often used in the computer field.

If you can use opencl, OpenGL, and OMAP for video processing, the computation speed will be greatly improved. This section briefly introduces how opencl and OpenGL work simultaneously.
Both opencl and OpenGL can be used for GPU operations, but the former is mainly used for general computing, while the latter is mainly used for image rendering. In some cases, we
For the arm Mali GPU, currently supports OpenCL1.1, so we can use OpenCL to speed up our calculations.There has been no environment for the Mali GPU to be tested for OPENCL programming. Finally got a Huawei Mate7, but because Huawei did not provide OpenCL driver (in the second half of the year, Huawei will have OpenCL

Original: http://villadora.me/2014/05/23/amd-define-and-how-to-translate-amd-to-commonjs/There has been a lot of controversy between Commonjs and AMD, and both have evolved and converged on the project. Personally, Commonjs is more developer-oriented, and for developers, it requires a clear version and management, less code and more interference, and less configu
Although AMD's day-to-day task is to zen the momentum, but after all Zen the fastest also have to be the end of the year or the beginning of the IPO. In such a gap, the addition of the upgrade is the pain before the dawn. As a representative of AMD High-performance CPU--FX series, although its historical evaluation has long been conclude, but the market always has a place for the FX series. This year, AMD s
1.OpenCL concept
OpenCL is a framework for writing programs for heterogeneous platforms, which can be composed of cpui, GPU, or other types of processors. OpenCL consists of a language for writing kernels (functions that run on OpenCL devices) (based on C99) and a set of APIs for defining and controlling the platform.
Cl_mem Clcreatebuffer (cl_context context, cl_mem_flags flags, size_t size, void *host_ptr, cl_int *errcode_ret) This function is used to create The Cache object. Context is the OPENCL context used to create the cached object. Flags is a bit field that indicates how and how the allocated cache objects are used. If the value of flags is zero, the default value of Cl_mem_read_write is used.

Anything beyond 3.7.2 and it's forks Don has GPU support, they has ASIC and FPGA support.The CPU mining support is dropped in the Cgminer 3.5 series.If you can ' t get your graphics cards to be recognized by Cgminer, that's not the fault of the blog owner, your ' re not Readi ng the instructions carefully and obviously not browsing the Cgminer (README) file, if you do, you ' d realize your error.

Earlier graphics cards were only used for display, and then 2D acceleration components were added to the graphics card, which were used for the operation of the screen, draw points, draw lines, and so on. With the need of game, three-dimensional simulation and scientific computing visualization, the demand for 3D is gradually increasing, the early drawing work is done by the CPU, to achieve realism and real-time effect, can only draw some simple wireframe model, in the 80 's, Stanford University
Xilinx, Inc. (NASDAQ:XLNX), the world leader in Programmable technology and devices, announced today the launch of OpenCL, C and c+ at the 2014 International Super Computing 2014 + SDACCELTM development environment, increase unit power performance by up to 25 times times, thereby using FPGA to achieve Data Center application acceleration. SDAccel is the newest member of the Xilinx SDX series, combining the industry's first architecture-optimized compi

Opencl Built-in functions to replace the code.
Opencl Built-in functions are generally directly supported by the GPU instruction set. Therefore, a call can basically be completed with only one instruction. So we are writing

Next is Multigpu and Openglinterop, but the two projects skip first. Because I have only one video card in My computer, and then I can't use it with OpenGL.
So the next step is the OpenCL scan project, and at first glance it feels very different from what it was before, and it's hard to look like.

OpenCL programming can use a struct, just provide the same structure declaration in the kernel function kernel.
If you define a struct in the main function:
1 typedef struct studentnode{
2 int age;
3 float height;
4}student;
The main function defines the data and transmits it to the OpenCL kernel:
Student *stu_input= (student*) malloc (sizeof (Studentnode));
stu_input->age=25;
stu_input->height=1.8
queue.The 2703 line involves the fence mechanism, which we'll cover in detail in the interrupt mechanism section.The same code that reads the indirect buffer mechanism is not too difficult.Indirect buffer to be able to function properly, it must be inserted into the code of the ring buffer, which is similar to inserting a "call xx" directive into the assembly code for function calls. The command added by the Radeon_ring_ib_execute function is equivalent to the call instruction used when the fun
This one test is the flagship model of the next generation of "Bristoal Ridge" processors: a12-9800. Compared to the previous generation of APU, this generation of AMD CPUs supports ddr4-2400 memory, NMVE protocol SSD, providing greater bandwidth and support for USB 3.1. From the extended functionality to catch up with Intel's mainstream processor. Let's take a look at the CPU performance of the a12-9800.

The previous blogs have described some of the DRM drivers, graphics card memory management mechanisms, and interrupt mechanisms, and it should be much easier to read the AMD DRM-driven initialization process.Here is an article written by an AMD developer (put it here for the time being, and then add your own view later).Understanding GPUs from the ground upI get asked a lot on learning how to program GPUs.
9 OpenCL OptionsThe --enable-opencl opencl option can be used globally when the configuration is turned on at FFmpeg compile time.The following are the supported options:

These days in the OpenCL Programming Guide, found a headache problem, programming sometimes with cl_int sometimes with int, and so on, began to understand that int is the grammatical structure of C, Cl_int is the grammatical structure of OpenCL, write the kernel with Cl_int, write C with Int. However, it is found that C sometimes has cl_int, and the kernel is basically int. Chaos, how can this?Difficulties
