submit commands to the device. A device has a command queue that is contextual. The command queue schedules the commands executed on the device. These commands are executed asynchronously in host programs and devices. There are two modes for the relationship between commands during execution: (1) sequential execution and (2) disorderly execution.
The execution of the kernel and the memory commands submitted to a queue generate event objects. This is used to control command execution and coord

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
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 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

First, you must know what platform on the opencl platform means. We know that different hardware vendors in different opencl organizations support the opencl standard, and each supporter will implement the specific implementation of opencl indep
