C Parallel Programming

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 be run on a large scale cluster by ...

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 ...

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 ...

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 ...

This paper mainly focuses on the synchronization mechanism of UPC, through a large number of program instances, so that the learners of UPC language can learn more comprehensively the usage of upc_barrier, upc_notify, upc_wait and upc_fence statements. Unified Parallel C (UPC) is a parallel programming language that supports multithreading. It is based on the C language to join the upc_barrier,upc_notify, and upc_wait statements to ...

Normally do we need a new programming language? You might think we do not need it. But if you understand the recent trends, your ideas may change. Why did Google use both GO and DART programming languages? Why did IBM, Cray and Red Hat create X10, Chapel and Ceylon respectively? In the future, these 10 programming languages ​​(DART, Ceylon, GO, F # OPA, Fantom, Zimb ...

Do we need a new programming language? You may not think you need it, but if you go to the latest trends, you may change your mind. Why does Google use go and dart two programming languages? Why do IBM, Cray, and Red hat create the three languages of X10, Chapel, and Ceylon, respectively? In the future, are these 10 programming languages (DART, Ceylon, go, F #, OPA, Fantom, Zimbu, X10, Haxe, Chapel) able to shake it. The new programming language is ...

Why create a Julia programming language? In a word, because we thirst for knowledge, constant pursuit. We have the core users of MATLAB, there are good at Lisp hackers, Pythonistas and rubyists experts also have a lot; In addition, there are some Perl Daniel, some developers used Mathematica before we had a little understanding of the fur. In other words, they understand more than just the fur, more than others, the development of R language. and C language for us is a deserted island. I ...
