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 procedure of the opencl program is roughly as follows:
The main code in source code is as follows:
Int main (INT argc, char * argv []){// Create three buffers in the host memoryFloat *

The following are the main codes

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

1 Hello opencl
Compile a simple example program to demonstrate the basic usage of opencl:
1. You can download an opencl SDK from the developer website of nvdia, AMD, Intel, or all opencl members. Although different companies support di

Now we use the method in the previous tutorial to count the number of pixels in a pair of rgba images (This pixel satisfies the arbitrary components of R, G, B, And a> = 5 )? The method I want to consider is to create a histogram of 256 bin. For a pixel, calculate max (R, G, B, A) and use this value to determine the pixel to enter the bin, after obtaining the histogram, the width * Height-hostbin [0]-hostbin [1]-hostbin [

Bank Conflicts is a common problem in storage access, and avoids bank Conflicts effectively improving storage access speed. The following is a description of two instances, reduction and prefix Sum.
1 use padding in reduction to avoid bank Conflicts
AMD HD Readon 5870 For example, the Local Memory has 32Banks, each wavefronts has 64threads, the Bank conflicts calculation formula is
Bank conflicts = STRI

Opencv experiences (1)
The second chapter of learning opencv mainly introduces some common and interesting functions and data types, so that students at the beginning are more interested in image processing, although I do not understand the internal experiment of the function and the meaning of some defined constants, I am still very happy after learning Chapter 2. At least I know some basics of image processing, such as contour processing;
