industry-standard OpenGL and OpenAL, which are used for three-dimensional graphics and computer audio, respectively, for the two standard. OpenCL extends the ability of the GPU to be used outside of graphics generation. OpenCL is run by Khronos Group, a nonprofit technology organization. In addition, OpenCL is a cross-platform standard and not a cross-platform t
For job requirements, the two high-level language synthesis tools were applied, and the typical algorithms were implemented and evaluated (data is temporarily kept secret).Briefly talk about the experience of using.1. Altera OpenCL SDKFirst, you need to install Quartus (more than 13.1 version) and the supporting Soc EDS, respectively, apply for two license, one for the OpenCL
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.

platform. Based on the current situation, if you select Intel's opencl SDK, you can only use intel's CPU for computing, if you select amd app SDK, you can perform amd cpu and amd gpu computing. Generally, Company A's platform cannot communicate with Company B's platform after it is selected.

opencl device includes one or more Cus (compute units ), each Cu includes one or more PES (process element ). Each PE has its own program counter (PC ). The host is the host device of the opencl Runtime Library. In the opencl platform of AMD and mongoda, the host generally refers to the x86 CPU.
For the amd platform, all CPUs are one device, each core of the CPU
Now, we start to write a simple OpenCL program, calculate the sum of the two arrays, and put them in another array. The program calculates with the CPU and GPU respectively, and finally verifies whether they are equal. The process of the OpenCL program is roughly as follows: The main code in sourcecode is: intmain (intargc, char * argv []) {
Now, we start to write a simple

Compile a simple example program to demonstrate the basic usage of opencl:

Now, we begin to write a simple OpenCL program that calculates the sum of two arrays and puts them in another array. The program calculates the CPU and GPU separately, and finally verifies that they are equal. The process of the OPENCL program is roughly as follows:
The following are the main codes
