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 ...

Large data "flooding": fusion of nuclear popularity parallel computing?

Beijing time this morning, Intel (Intel) officially released the Xeon Phi (Xeon) coprocessor based on an integrated Salt Lake City (MIC) architecture at the supercomputer (SC12) Conference held in the city. One of the Xeon Phi coprocessor 5110P with the date of shipment, January 28, 2013 GA, recommended customer price of 2649 dollars; Xeon Phi Coprocessor 3,110 families will be available in the first half of 2013, advising customers price less than 2000 U.S. dollars. Intel Xeon Phi Coprocessor Home ...

The technique of cable-bell filter based on parallel programming

Cable-Bell filter technology based on parallel programming computation Xu Changlong Wang Smart Shuo Hua with the increase of the data volume of remote sensing image, the computation time of the edge filtering operation in a single environment is also greatly 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. ...

-mapreduce of functional programming paradigm

One months ago, I was asked what is functional programming? Although familiar with some of the concept of functional programming, the Little Schemer bought from Canada six months ago also read the previous chapters, that day is not able to answer what is functional programming. Functional programming is a strange field for programmers familiar with procedural programming, and concepts such as closures (closure), continuations (continuation), and currying are a nightmare for programmers with procedural programming. Without u ...
