The main objective of the supply Chain Master planning module (master calculates) is to enable the material to flow synchronously throughout the supply chain. The Supply Chain Master planning module provides a way to make medium-term decision making for effective utilization of production, transportation, supply capacity, seasonal inventory and balance of supply and demand. The result of synchronization is that the production and distribution departments can reduce the corresponding inventory levels. Without centralized control of the Master planning module, a large amount of buffer inventory must be added in order to ensure a continuous flow of material. By reducing the degree of change in production and distribution, the Synergy Master plan can reduce these security eases ...

This paper is an excerpt from the book "The Authoritative Guide to Hadoop", published by Tsinghua University Press, which is the author of Tom White, the School of Data Science and engineering, East China Normal University. This book begins with the origins of Hadoop, and integrates theory and practice to introduce Hadoop as an ideal tool for high-performance processing of massive datasets. The book consists of 16 chapters, 3 appendices, covering topics including: Haddoop;mapreduce;hadoop Distributed file system; Hadoop I/O, MapReduce application Open ...

The cloud computing concept originated in super large-scale internet companies such as Google and Amazon, and with the success of these companies, cloud computing, as its supporting technology, has been highly recognized and widely disseminated by the industry. Today, cloud computing has been widely regarded as the new phase of IT industry development, which has been endowed with a lot of industry and product level significance. Because of the multiplicity of meanings, various concepts are complex, many companies and practitioners have their own cloud, as Xu Zhimo in the "accidental" a poem said: "I am a cloud in the sky, and occasionally projected in your wave heart." Traditional ...

In MapReduce, shuffle is more like the inverse process of shuffling, which refers to "disrupting" the random output of the map end according to the specified rules into data with certain rules so that the reduce end can receive and process it.

1 Hadoop pipeline improvement in the implementation of the Hadoop system, the output data of the map end is written to the local disk first, and the Jobtracker is notified when the native task is completed, and then the reduce end sends an HTTP request after receiving the Jobtracker notification. Pull back the output from the corresponding map end using the Copy method. 　　This can only wait for the map task to complete before the reduce task begins, and the execution of the map task and the reduce task is detached. Our improvement ...

The big data boom has sparked a major change in thinking, production and lifestyles, and it can be said that a new era has been opened up. For the financial industry with natural data attribute, on the one hand, large data can provide sufficient information support for the operation and management of financial institutions. On the other hand, large data-breeding new financial forms pose serious challenges to traditional financial institutions. What the financial institutions will do in this great social revolution is very much expected. 　　To this end, The Economist has invited a number of senior managers of financial institutions as well as industry experts to explore the financial sector in the big data era of change and development. ...

With the rise of new businesses such as cloud computing, mobile Internet and Web2.0, traditional data centers have been unable to meet. The industry is setting off a new wave of data center construction, with the next generation of cloud computing data centers. Network is one of the important components of cloud data center, the network Architecture of cloud data center must have five new technology features: 100G Ethernet technology, surge cache, network virtualization, unified Exchange, green energy-saving technology. 100G Ethernet Technology Bandwidth pressure is the core problem of cloud data center network. In the data center, like video-on-demand, 10G FCoE ...
