What Is a Grid Code?

As a new type of network that can bring huge processing, storage capacity and other IT resources, the grid can cope with temporary use.

In order to solve the problems of complex scientific computing and massive data services in different fields, people have constructed different

Because the internet structure is not targeted

Maybe everyone will first ask what is cloud computing.

Grid Technology Cloud Computing

Cloud computing (CloudComputing) is the development of distributed processing (ParallelComputing), parallel processing (ParallelComputing) and grid computing (GridComputing), or a commercial implementation of these computer science concepts.

The basic principle of cloud computing is that by making computing distributed on a large number of distributed computers, rather than local computers or remote servers, the operation of enterprise data centers will be more similar to the Internet. This enables companies to switch resources to the applications they need and access computers and storage systems as needed.

The PC is a core tool in our daily work life: we use the PC to process documents, store information, and share information with others via email or USB flash drive. If the PC hard drive is broken, we will be at a loss because of data loss. In the "cloud computing" era, the "cloud" will do storage and computing for us. The "cloud" is a group of computers, each of which includes hundreds of thousands or even millions of computers. The advantage of the "cloud" is that the computers in it can be updated at any time to ensure that the "cloud" is immortal.

Grid computing

However, on the other hand, we cannot fail to mention the grid computing technology currently in use. A grid is a series of distributed computing resources provided through a local area network or a wide area network. To the end user or application, it seems like a large virtual machine. computer. This vision is to create a virtual, dynamic organization by enabling secure, coordinated resource sharing among individuals, organizations, and resources. Grid computing is a method of distributed computing that includes not only deployment, but also organizations, hardware, and software to provide unlimited capabilities so that everyone connected to the grid can collaborate and access information. Grid computing is also a method applied to distributed computing, but it can be said that in many ways, cloud computing is a leap in grid computing technology.

Comparison of grid technology

First, we can compare the job scheduling aspects of grid computing. Job scheduling is the core value of grid technology. The goal of grid is to use as many resources as possible. It uses a specific grid software to decompose a huge project into countless independent, less relevant subtasks, and then passes it to each computing node for calculation. Even if there is a problem with a node, the failure to return the results in a timely manner does not affect the progress of the entire project, and even if a computing node suddenly crashes, the computing tasks undertaken by it can be assigned to other nodes to complete the task scheduling system.

Cloud computing also constructs all resources into a huge resource pool like grid computing. However, a certain resource provided by cloud computing is to complete a specific task. For example, a user may need to request a certain amount of resources from the resource pool to deploy their application, without submitting their own tasks to the entire grid to complete. From this point of view, the construction of the grid is mostly required to complete a specific task, which is why there are various grid projects such as biological grids, geographic grids, and national education grids. Cloud computing is generally designed for general-purpose applications. There is no special grid named after an application.

Secondly, cloud computing will have three major impacts: impact on Internet applications, impact on product application models, and impact on the development direction of IT products. Of course, the so-called change is not a complete subversion, but a new feature. This advantage is a challenge to grid technology. Grid computing also has the following advantages when it is produced: Any computer can provide unlimited computing power and can access a wealth of information. This environment will enable companies to solve previously difficult problems, use their systems most effectively, meet customer requirements, and reduce their total cost of ownership and management of computer resources.

But for cloud computing, it is a greater extension of these advantages. In the future, through cloud computing, more applications can be implemented as Internet services. Cloud computing will expand the extension of software and hardware applications and change the application model of software and hardware products. Through cloud computing, users can get the application environment or the application itself without having to purchase new servers and deploy software. For users, software and hardware do not have to be dedicated products dedicated to them, but can be turned into an available and virtual resource. Moreover, the software and hardware resources that can be used are not limited to the equipment and software inside the enterprise itself, but can be extended through the network. The development direction of IT products will also change to adapt to the above two situations ^[1] .
