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 hardware features may be considered for program optimization].
Generally, the opencl architecture consists of four parts:
Platform mo
trying and improving, and CommonJS is an important organization. They proposed many new JavaScript architecture solutions and standards, hoping to provide a uniform guide for front-end development.
AMD specification is one of the most famous ones. Its full name is Asynchronous Module Definition, that is, Asynchronous Module loading mechanism. From its standard description page, AMD is very short and simple
Introduction to JavaScript AMD specifications (1)AMD stands for "Asynchronous Module Definition", which means "Asynchronous Module Definition ". AMD defines that all modules we use are asynchronously loaded, so we need to put the code snippets of the dependent modules in a callback function, after the asynchronous load
specification). The Mesa source package contains a large number of OpenGL sample programs, including sample code in OpenGL Red Book, code to invoke glut or GLX interfaces, code to invoke EGL, and so on.Figure 1Figure 1 shows the process of a 3D application running, the OpenGL drawing program commands are translated into the command buffer by the MESA driver of the user space, and other such as vertex information/texture information/index information
The Commonjs loading module is synchronous, and the AMD module is added to the non-synchronous, allowing for the designation of the callback function. Since Nodejs is mainly used for server programming, module files are generally present in the local, so load quickly, do not need to consider the non-synchronous loading, with COMMONJS can. But the browser is loaded from the server module, which requires the use of non-synchronous mode, GU Select
. For example, multi-core CPU is suitable for Task-based parallel programming, GPU is more suitable for Data Parallel Programming.

driver of the graphics system, due to the graphics system, the graphics card itself is more complex, and for some historical reasons, the graphics system is driven outside the core core, and the graphics card driver is the most important part of the core outside. On the newest page of the wiki entry "free and Open-source graphics device driver", there is a good illustration of the evolution of the graphics system in the Linux environment, which is described directly using the diagram of this pa

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 proce
To get this topic, we will first think of using loops to complete.But not every operator is a "+" sign.Therefore, we are here to use (-1) of the I-side to do "+" "-" number control.The loop variable i is then treated as the denominator.Here we have the idea of the loop body is basically OK.It is important to note that the calculation results here are expressed in decimals, so it is not possible to define variables with int integers.The code is as foll
