"Graphics" distributed parallel programming with Hadoop (i)

Hadoop is an open source distributed parallel programming framework that realizes the MapReduce computing model, with the help of Hadoop, programmers can easily write distributed parallel program, run it on computer cluster, and complete the computation of massive data. This paper will introduce the basic concepts of MapReduce computing model, distributed parallel computing, and the installation and deployment of Hadoop and its basic operation methods. Introduction to Hadoop Hadoop is an open-source, distributed, parallel programming framework that can run on large clusters.

Domestic cloud service providers need parallel computing services

The author of this paper, Qi Haijiang, Qingdao Five-Pulse Spring Information Co., Ltd. Technical director, University of Pennsylvania Bioengineering, Ph. D., Nanjing University. For many years engaged in graphic images, 3D vision, neural computing, machine learning algorithms such as research. "Abstract" cloud computing services is essentially a sharing of social intelligence resources, through the cloud of technology packets, reducing the difficulty threshold, so that more users can use "very advanced" technology. China's mobile interconnection new economy is highly prosperous, need to have the corresponding technology high cloud computing service as keel support. Today's computing is the obvious trend: Video audio graphics + ...

Analysis of cloud computing distributed parallel computing: programming model

MapReduce is a distributed programming model developed by Google for mass data processing in large-scale groups. It implements two functions: map applies a function to all members of the collection, and then returns a result set based on this processing. and reduce is the classification and generalization of result sets that are processed in parallel by multiple threads, processes, or stand-alone systems from two or more maps. The Map () and Reduce () two functions may run in parallel, even if not in the same system ...

Building high performance distributed parallel computing environment based on MPICH2 in Linux system

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 ...

Distributed parallel programming with Hadoop, part 3rd

Foreword in the first article of this series: using Hadoop for distributed parallel programming, part 1th: Basic concepts and installation deployment, introduced the MapReduce computing model, Distributed File System HDFS, distributed parallel Computing and other basic principles, and detailed how to install Hadoop, How to run a parallel program based on Hadoop in a stand-alone and pseudo distributed environment (with multiple process simulations on a single machine). In the second article of this series: using Hadoop for distributed parallel programming, ...

Cloud computing with Linux and Apache Hadoop

Companies such as IBM®, Google, VMWare and Amazon have started offering cloud computing products and strategies. This article explains how to build a MapReduce framework using Apache Hadoop to build a Hadoop cluster and how to create a sample MapReduce application that runs on Hadoop. Also discusses how to set time/disk-consuming ...

A thorough interpretation of "It Tomorrow Star" cloud computing

The distributed computing technology proposed by Google makes it easy for developers to develop global application services, and cloud computing technology automates the management of communication, task allocation, and distributed storage among a large number of standardized (heterogeneous) computers.   The cloud comes from a decentralized, parallel operation, but better than the grid. Data computing cloud technology can be considered as a sub-set of grid technology, both of which are designed to hide the complexity of the system, so that users need to use it without knowing how the system works inside. The parties follow up with Google to promote cloud services, but the definition is different ...

Deep analysis of the specific technologies used behind cloud computing

As a new computing model, cloud computing is still in its early stage of development. Many different sizes and types of providers provide their own cloud-based application services. This paper introduces three typical cloud computing implementations, such as Amazon, Google and IBM, to analyze the specific technology behind "cloud computing", to analyze the current cloud computing platform construction method and the application construction way. Chen Zheng People's Republic of Tsinghua University 1:google cloud computing platform and application Google's cloud computing technology is actually for go ...

Hadoop: Calculate pi pi with parallel computation

About pi Everyone is familiar with: we learn from the textbook to as early as more than 1000 years ago, zu Pi to 3.1415926 to 3.1415927 ... After the birth of the computer, calculate pi is used to detect computer hardware performance, day and night burning CPU to see if there is a problem ... Others also want to see if there is a rule behind this mysterious figure of infinite extension, to discover some cosmic secrets ... Mention PI, cannot mention Fabrice Bellard, he is considered a computer genius, in the industry has ...
