What is rendering) A simple understanding of rendering may be like this: it is to convert the description of a 3D object or a 3D scene into a two-dimensional image, and the generated two-dimensional image can well reflect a 3D object or a 3D scene (1): What is a rendering pipeline? A rendering pipeline, also known as a rendering pipeline, is a parallel p

Resolution: (1) formula for throughput: Number of commands divided by the time of the pipeline (2) formula for calculating the time of the pipeline: time required for a command + (number of command lines-1) * The longest instruction period7 + (8-1) * 3Assembly line:A pipeline is a quasi-parallel processing technology that allows multiple commands to overlap durin

A pipe is the earliest form of communication between Unix processes. It exists in all UNIX implementations. You need to know the following about pipelines: 1. It is half-duplex, that is, data can only flow in one direction. Although pipelines can be full-duplex in Some UNIX implementations, some system settings are required. In Linux, it is half-duplex. 2. It has no name, so it can only be used between processes with common ancestor. It is usually used between parent and child processes. Althoug

Translated from OpenGL wiki: http://www.opengl.org/wiki/rendering_pipeline_overviewPipelines The OpenGL rendering pipeline works as follows: 1. Prepare and render vertex array data 2. vertex processing: 1. Each vertex must be processed by the vertex coloring tool. Each vertex is processed as an output vertex in sequence in the data stream; 2. Optional fragment stages of element and surface; 3. optional element geometric coloring machine processing, ou

NET 3.5 to manage, but requires IIS7 version and aboveSo ask

Famous pipe nameless pipe and famous pipe:1. Pipeline is a special type of file, in the first-in- first-out to meet the principle of write can read and write, cannot locate read-write location.2. The piping is unidirectional.3. The nameless pipe is blocked in the read-write location , and the famous pipe is blocked at the creation location .4. nameless pipes are generally used only for inter- relationship interprocess communication; A well- known

Anonymous pipelineA pipeline is a one-way channel, a bit like a shared-memory cache. The pipe has both ends, including inputs and outputs. For a process, it sees only one end of the pipe, either the input or the output.Os.pipe () returns 2 file descriptors (R, W), which represent both readable and writable. The sample code is as follows:#!/usr/bin/pythonImportTimeImportOs def child(wpipe):Print' Hello from child ', Os.getpid ()) while True: Msg =' How

Communication effects between processes1. Data transfer: A process needs to upload his data to other processes2. Resource Sharing3. Process notification Events4, Process Control: Some processes completely control the execution of another process, such as debug State AHWe need to take full control of his every step of the operation;Communication development HistoryThe communication IPC between Linux processes evolved from the following sections:1. Communication between UNIX processes2. Communicat

The previous section learned the Nameless pipe, which learns named Pipes.Two Named pipesNameless pipes can only be used to communicate between a parent-child process or sibling process, which brings trouble to the exchange of data between unrelated processes, and solving this problem is another pipeline communication for this SectionTo learning: Named pipes.A named pipe is also known as a FIFO file, and the FIFO differs from the

main content: Anonymous pipe, command pipeline. (Pipe, Popen, Mkfifo functions) Pipe Introduction: Pipelines are a way of communicating between processes, which is equivalent to having a tunnel between two processes that can pass the message through the tunnel; The pipe is located outside the address space of the process, and the pipe is divided into anonymous pipes and named pipes two kinds;anonymous pipes are created by pipe, and named Pipes are cr

To clearly explain the meaning of vertex coloring and fragment coloring, we start with the elaboration of two component

only be used between two processes with a common ancestor, that is, two processes can only be parent-child processes or two child processes with a common parent process.known pipeline (FIFO):A nameless pipe can only be used between two related processes (two processes have a common ancestor), but through FIFO,Unrelated processes can also exchange data for communication。 The commonly used implementation function is MKFIFO (path, mode), which creates a

1. What is a pipe?Pipelines are divided into nameless pipes and named Pipes, and no special instructions in this article refer to nameless pipes.The pipeline is one of the original UNIX IPC forms supported by Linux and has the following features:A. The pipeline is half-duplex, the data can only flow in one direction, when two sides need to communicate, need to set up two pipelines;B. Can only be used betwee
