Network File System Nfs

The network filesystem (nfs,network file system) is a mechanism by which partitions (directories) on a remote host are mounted over the network to the local system, which enables users to share partitions (directories) on the remote host, as if they were operating on the local system, by supporting the network file system. . In the development of embedded Linux, developers need to do all the software development on the Linux server, cross compile, the general FTP way to download the executable file to the embedded system operation, but this way not only effective ...

The file system is the method and data structure that the operating system saves the file information on the hard disk or partition, that is, how the file is organized on the hard disk or partition. Typically, it is also used as a hard disk or partition that represents the file information that is saved. File system type supported by 8.5.1 system One of the important features of Linux systems is supporting multiple file systems. In this way, it is more flexible and can exchange data with many other kinds of operating systems, where Yun is commonly used in the following ways: Ext3:ext2 upgrade, Red Flag Linux http://ww ...

Now almost any application, such as a website, a web app and a mobile app, needs a picture display function, which is very important for the picture function from the bottom up. Must have a forward-looking planning picture server, picture upload and download speed is of crucial importance, of course, this is not to say that it is to engage in a very NB architecture, at least with some scalability and stability. Although all kinds of architecture design, I am here to talk about some of my personal ideas. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...

MPICH2 provides a platform for parallel and distributed processing of large data under existing hardware and software architectures. This article will describe how to build a high-performance distributed parallel computing environment based on MPICH2 in Linux systems. MPI (Message passing Interface) is a messaging standard developed by the MPI Committee, which defines a series of programming interfaces for interprocess communication in a distributed environment, currently with MPI-1 and MPI-2 two versions. MPICH2 ...
