Distributed Computing

Cloud computing is more and more people are familiar with it in the end is what the concept or something you? The following Gartner given the definition, and has become a mainstream classic and a large number of references: Cloud computing is "a style of computing where massively scalable IT -related capabilities are provided 'as a service' across the ...

Cable-Bell filter technology based on parallel programming computing model Xu Changlong Wang clever Shuo Hua with the increase of the data of remote sensing image, the computation time of the edge filtering operation of the cable-bell in single environment is also increased. According to the characteristics of remote sensing data, combined with MapReduce parallel distributed computing model, this paper proposes a method of migrating this operation into Hadoop cluster environment to complete the Bayes filtering operation of massive image data. The experimental results show that the cluster operation can shorten the computation time, and the calculation time will decrease with the increase of cluster node number. ...

Shekhar Gulati, an Indian Java programmer, has published "How I explained MapReduce to my Wife" on his blog. The concept of MapReduce is described in a more popular way. As follows, the translator is the Huanghui Oracle online. Yesterday, I delivered a speech about MapReduce in the Xebia India Office. The speech went well and the listeners were able to understand the MapReduce concept (...).

The word cloud was born in the third quarter of 2007, in English (cloudcomputing), but after only six months, the word was more focused than grid computing. However, there are at least 100 or more of them that can be explained by cloud computing, until now there is no accepted definition. One of the most widely accepted claims at home is the definition given by Professor Peng, the deputy director of China's cloud computing expert Advisory Committee, that "cloud computing provides scalable, inexpensive, and distributed computing power over the network." Cloud computing is now ...

Cloud computing is a very popular concept nowadays. What kind of a good thing is it? The following Gartner-given definitions have become classic and are heavily referenced: Cloud computing is "a style of computing where massively scalable It-related capabilities are provided ' as a service ' across the Internet to mul ...

Research on load Balancing strategy of Distributed system South University Li Deng Although load balancing has been studied for nearly 20 years, the load balancing strategy is a NP complete problem, and the real satisfying system is not many. In this paper, the distributed system and distributed object technology are discussed, and then the algorithm and model of load balancing are studied in detail, and the reasons of extra cost are studied, and the difficulties in the research of load balancing strategy are researched. The innovation of this paper is to put forward the information center scheduling strategy, which is widely studied in the current typical load ...

Large-scale distributed solution of packet Dantzig Selector Liang of China University of Science and technology the main work of this paper includes: (1) using the Dantzig selector to solve the linear characteristics of the path piecewise, the Dasso algorithm to improve the Dantzig selector, The superiority of the improved algorithm is highlighted by comparing with the linear alternating direction multiplier method. (2) Overcome the difficulty of solving the constraint condition in the packet Dantzig selector, introduce the intermediate variable to simplify, and apply the alternating direction multiplier method (ADMM) and the alternating direction of linearization.

Design and implementation of distributed computing framework for mass remote sensing images Cheng Miaofang Yang Wenhui Chen Ken in view of the processing and computation of the massive remote sensing image, based on the MapReduce calculation model, a distributed computing framework SPC (Split Process) suitable for mass remote sensing images is designed and implemented. Cluster). The SPC framework can segment the remote sensing image data, and then the distributed processing through Hadoop, finally, the clustering algorithm is adopted to merge the results, so as to realize the distributed processing of mass remote sensing images. Test knot ...

In October 2016, Alibaba Cloud announced a comprehensive reduction in the price of cloud products in China, with a maximum drop of 50%. This is the 17th price cut by Alibaba Cloud in one year.

Why is cloud computing successful? The success of cloud computing can be said to be "weather, geography, people and" the result of the comprehensive effect. "Timing" here refers to the timing of the introduction of concepts, "geographical location" refers to the concept of the technical basis, and "people and" is a lot of concepts advocates and huge market demand. Only the technology and market base can sometimes not be successful, but also need to have the right time. The financial crisis that swept the world in 2008 gave the cloud a chance. Affected by the financial crisis, a large number of companies to cut it costs, the original bulk of the procurement has been unable to ...

The platform can be divided into three categories: a storage-based cloud platform based on data storage, a computational cloud platform based on data processing, and an integrated cloud computing platform that combines computing and data storage processing.
