(1) Learning APUE file IO and apue file io together . . . . . I have been learning APUE recently. By the way, I have recorded what I learned every day. On the one hand, I want to consolidate my learning knowledge and on the other hand, I want to provide a reference for the kids who are also learning APUE. This series of blog posts are summarized in the book "Advanced Programming for UNIX environments". If y

Java IO learning notes (5) object stream and io learning notes1. Object stream: directly write or read the Object. 2. serialization: directly convert an Object into a word and write it to a hard disk or network. 3. If you want to convert an object into word throttling, the object class of this object must implement the Serializable interface. The Serializable interface is a mark interface and has no method,

Java (4) -- IO stream, java -- io stream(1) Java Stream Input/Output Principle: In a Java program, input/output operations on data are performed in the stream mode to obtain different types of data. The program inputs or outputs data through standard methods. (2) java. io abstract stream classification: Node stream and processing stream: The node stream ca

What is io:(input/output): input and output.IO device: a device that communicates with a computer.input device: microphone, scanner, keyboard, mouse and so on.output Devices: monitors, printers, projectors, headphones, audio, etc.Why does the program need IO ?Case 1: Play game operation, score higher, store game information.In this case, you need to store the data in the game and only store it in the file.C

Performance Tuning: IO consumption analysis, performance tuning io consumption Performance Tuning-> how to analyze io consumption Reprinted please indicate the source: http://blog.csdn.net/supera_li/article/details/45225077For more information about the performance tuning series, see.Performance Optimization: Analysis of CPU consumptionPerformance Optimization:

1, event channel model. The event channel is the prototype of asynchronous IO.2, io mode, one IO call will go through two stages. First, wait for the data phase, the data from the network or disk read to the system kernel (kennel) Two, the data from the kernel copy into the process.Based on these two phases, the Linux system generates five network mode scenarios.

The use of MPI-2 parallel IO, mpi-2 parallel io The MPI program needs to use parallel IO to operate files, but du Niang does not find many methods to use parallel IO functions. Finally, I found some useful papers on zhiwang. After reading them, I felt very open. MPI-1 operations on files are carried out by using the fu

Java asynchronous IO and java asynchronous io The key points of the new asynchronous functions are some subsets of the Channel class. The Channel needs to be switched to a background process when processing IO operations. You can use this function to access large, time-consuming operations or other similar instances.Here, we will only explain the AsynchronousFile

Server performance indicators As a network server program, performance is always the first indicator. Performance can be defined as the number of tasks that can be processed in a given hardware condition and time. The server design that maximizes the use of hardware performance is a good design.A well-designed server should also consider the average service. For each client, the server should provide the average service to each client, so that a client cannot be served for a long time and the se

Node. js uses the socket. io method, node. jssocket. io You can use socket. io to create a socket. io server. However, this server depends on a created http server. After the http server is running, use the listen method to append a socket. io server to the http server. Copy
