How to create parallel tasks using parallel for loops

Hello

I'm going to put in place a program that communicates with the six logical controllers and must read the status of the system every 100 Ms. we use OPC datasockets for this, and they appear a bit slow.

I created a uniform method of comm. for all controllers, and now I find myself this method of programming six times to communicate with each system. I was wondering if it could be done more elegant using the parallel for loop, in which case I program an Exchange once and then six workers running simultaneously. Since a picture is clearer than a thousand words, what I'm asking is:

Is it possible to replace something like

by

and that for performing these tasks in parallel loop (on different cores / in different threads)?

I have configured the loop to create instances of the 8 to the compilation, so I would 2 surplus available when running instances if I find that I need an additional system.

The benefits of the Show method in the second photo for me are:

* takes less space

* changes need be made only once

* less blocks, son and other things makes it clearer what is happening.

* flexibility of the actual number of tasks running (8 available runtime instances)

* If multiple tasks are necessary, I need only update the maximum number of instances and recompile, i.e. no cutting and pasting necessary.

Unfortunately, I don't have these available system yet, so there is no way to test this. Yet, I would like to know if the above works as I hope - unfortunately the help of labview is not quite clear to me on that.

Best regards

Frans

Frans, the parallel for loop will work as expected in this situation. The six tasks will run simultaneously in different threads. What part of the aid could be made clearer?

  • How to create a positioning using Dw for 2015

    Hi, I'm working my way through tutorial CSS Layouts from Train Simple, which is not yet in 2015 mode.  I am in terms of relative positioning and open the page that contains two items on it.  The guardian said > div tag and then create the new item that I made - it now appears in the window of the selector and the DOM, but I can't find the positioning options window on my workspace.  I double clicked on everything but can not find the placement options is absolute to parent (shown in 2014).  I tried the online help of Dw and even YouTube but found nothing.  Train Simple informs me that the new 2015 updated tutorial is about to be released but tempus fugits!

  • How to create a chart using two independent loops while?

    Hello world

    I'm currently developing a program for the acquisition of data. In this program, I have two independent, while loops that each output a number of type double with each iteration of the loop. I am able to successfully create two independent waveform graphs (data / time) for each of the loops when placed inside. However, I now want to create a live data xy chart (the output of a loop is x and the output of the other is there).

    I have a problem, that the distinct nature of loops... When I try to extract data outside of the loop (naturally), it is not refresh with each iteration of the loop causing the graph xy does not work in the way I intend. Is there an easy way to solve this problem? If more clarification is needed, please let me know!

    David

    If the two loops are not synchronized, exactly how do you do the xy graph, where each point, by definition, must have a value of each loop.

    1. updated when updates or the other value and combine with the last value from the other loop?
    2. updated on a constant basis with the current value of each loop?
    3. ... There are many other possibilities.

    #2 is the easiest. Simply create a third loop with a reasonable time and graph the two values via local variables. You probably also should limit the history of ranking somehow.

  • How to create a task that runs once a day, immediately after the opening of session?

    Hello, I'm wondering how to create a task using the Task Scheduler that runs once a day, immediately after I have logon.

    The reason is I want to use Bing Desktop to change my wallpaper every day. However, I just want to run the first time I start my computer every day, so it will change the wallpaper. By default, it starts whenever I have to logon. It's annoying, because I just want it to start once a day to change the wallpaper. However, using the Task Scheduler, I put only a trigger to start "at the opening of session' or"once a day." If I choose once per day, it runs about 5-10 min after I login, instead of logon immediately after. If I choose the two triggers, then it starts after each session.

    Basically, I just want the Task Scheduler to launch the program after the connection the first time I connect to the computer on any given day. How can I do this?

    A parallel FOR loop has an overhead for parallelization (split the problem, then go back the results, etc.). If the code is very fast, the overhead is proportionally larger. If the Subvi takes a long time to complete, the overhead of parallelization is insignificant. It is often not worthwhile to parallelize the loops with a very simple and fast code.

  • Parallel for loop 2D table

    Hello

    I don't have any experience with parallel for loops, so I need your help.

    Goal: To do a calculation (average, average) on the rows (or columns) table 2D as quickly as possible. The calculations are independent of each other and I would get a table 1 d with the results.

    I read a few posts on parallel for loops and I would like to find an example for my trivial problem, but I can't.

    Could you help me, it is possible is improve it the effectiveness of the calculation on lines with parallelism in LabVIEW? and it is, could you post an example how to do?

    Thank you

    If the speed issues, do not write your own "average." First of all, it already is in the range of statistics, but then you must be inline your average VI or do the calculation explicitly (as shown below). the size of the array never changes for the duration of the loop, it seems redundant to get the size of the array on each iteration.

    Here's what you could do.

    On my bench, it's much faster than the use of 'mean.vi' of the palette. Average a overhead, Subvi (1) (2) needs to get N with each call and (3) is also an unnecessary error checking.

    (Sorry, I have 32 processors, so the number of instances is set a little high. Modify if needed).

  • LabVIEW parallel for loop and OpenMP

    Hello:

    It's just a curious post, I just learned about OpenMP and I found that OpenMP helps you to parallelize loops in c about the same way that you can use the loop For parallel in LabVIEW.

    The loop For Parallel LabVIEW is being implemented under the hood using OpenMP? Or is it just a coincidence?

    No, it is not implemented LabVIEW parallel for loop under the hood using OpenMP. You might be interested to read this article on modern developments in the LabVIEW compiler architecture. Specifically, in this case, it's the DFIR technology discussed here that facilitates parallel for loop transformations.

    Can't do much about that because it depends on what authenticate you the VPN server and how the settings. But let me introduce you to the memory layout. Once you install and open a VPN client. Press it again and it opens up a new page for the VPN config.
