   • Parallel processing using "parallel" in R

     Parallel processing allows your application to do more tasks in less time. These assist in solving significant issues. In this article, we are going to look at how we can do parallel processing using the parallel library in R Programming Language.

     Using parallel library

     The parallel is a base package that was included in R 2.14.0. It expands on the work done for CRAN packages multicore and snow and offers drop-in substitutes for the majority of those packages’ capabilities,

     You can import the library using the following command:

     library(parallel)

     You can also check the number of cores in your system using the library. The following code does the same:

     R

     library(parallel) detectCores()-

     Output:

     8

     Methods of Parallelisation

     The code can be parallelized primarily in one of two ways: either using sockets or by forking.

     Using sockets with parLapply()

     This kind of parallel processing is slower and more difficult to use. The standard procedure we’ll use is as follows:

     • Start an n-node cluster.
     • Run any necessary pre-processing code in each node.

   • Parallel processing with Numpy.loadtxt()

     It looks like numpy.loadtxt() is your problem.

     http://codrspace.com/durden/performance-lessons-for-reading-ascii-files-into-numpy-arrays/

     According to these sites, you're better off not using numpy's load function at all.

     pandas.read_csv and read_table should be helpful from the pandas module.

   • Parallel Processing using Java and Spring

     Top Answer

     Glaring performance is based on the design of spring batch implementation and we are sure you will get with spring batch as we are processing millions of records with select delete and update.

     • Each user's record should get executed parllely. Each user can have maximum of 1.5 lakh records."Partition the selection based on User and Each user will run as parallel steps."
     • Every user can have update and delete records. Update records should run before delete." Create a Composite Writer and delegates added for update Ist writer and delete 2nd writer "
     • Update/delete sets should run parallel on their own. But strictly all updates should complete before delete."Each writer step update and delete manages the transaction and make sure update executes first ".

     Please refer below

     Spring Batch - Read a byte stream, process, write to 2 different csv files convert them to Input stream and store it to ECS and then write to Database

     Why don't you use the much simpler parfor? At the moment you're running the loop on each workers, and I assume that you wanted to run the iterations of the loop in parallel.

     nIter = 10;result = zeros(1, nIter);-matlabpool open local 2 parfor a = 1:nIter data = generate_data(); fprintf('%s: processing set %i/%i\n',datestr(now),a,nIter) result(a) = process_data(data); endendmatlabpool close

     This answer is outdated. Please see this answer instead.

     Your code will run concurrently, but not in parallel. You can make it run in parallel by setting GOMAXPROCS.

     It's not clear exactly what you're trying to accomplish here, but it looks like a perfectly valid way of achieving concurrency to me.

   What is parallel processing in Computer Science?

   • In general, parallel processing refers to dividing a task between at least two microprocessors. The idea is very straightforward: a computer scientist uses specialized software created for the task to break down a complex problem into its component elements. Then, they designate a specific processor for each part.

   How does parallel computing work?

   • Parallel computing, on the other hand, uses multiple processing elements simultaneously to solve a problem. This is accomplished by breaking the problem into independent parts so that each processing element can execute its part of the algorithm simultaneously with the others.

   What is the difference between parallel and serial processing?

   • Complex operations and computations are frequently completed in parallel processing. At the most fundamental level, the way registers are used distinguishes between parallel and serial operations. Shift registers operate serially, processing each bit one at a time, whereas registers with parallel loading process each bit of the word simultaneously.

   What happens when processing is done in parallel?

   • When processing is done in parallel, a big job is broken down into several smaller jobs better suited to the number, size, and type of available processing units. After the task is divided, each processor starts working on its part without talking to the others.

   Parallel computing is a type of computation in which many calculations or processes are carried out simultaneously. [1] Large problems can often be divided into smaller ones, which can then be solved at the same time. There are several different forms of parallel computing: bit-level, instruction-level, data, and task parallelism.
