• For loop in place, images to scale and move

  I have an image which I enclose, is the white part of the image (I recorded it on a black background so it is easy to see, but it's on a transparent background, saved as a gif file and imported to flash). When my for loop runs, I'm trying to put this image on stage by programming, but it seems that it is not doing things. It will scale the image and positioned some in all directions

  I wanted the images (8) appears in 2 columns each staggered regularly, but he fails to do so. The clip holds the image below. Since it is an irregular shape, it also seems to make the edges really rough.

  (1) why is the loop generating these images in all directions like this?

  (2) it would be more ideal to draw this shape with flash, rather than by using a gif image? Such a form is even possible to draw?

  This is the code:

  Fl.transitions import. *;
  Fl.transitions.easing import. *;
  import flash.events.TimerEvent;

  var imageLoader:Loader;

  var xmlData:XML;

  var bucketItem:MovieClip; They hold the attached picture
  var bucketHor:MovieClip;

  placeBuckets();

  public function set {loadedXML(xml:XML):void}
  xmlData = xml;
  }

  function placeBuckets (): void {}
  var all: Number = 50;
  After var: number = 115;
  
  var bucketCount:XMLList = xmlData.product;
  for (var u: uint = 0; u < bucketCount.length (); u ++) {}
  bucketItem = new bucket();
  bucketHor = new bucketr();
  
  If (bucketCount.country.text ([u]) == 'USA') {}
  1st = bucketItem.y;
  bucketItem.x = 100;
  var bucketTween:Tween = new Tween (bucketItem, "x", Regular.easeOut, bucketItem.x, 0, 0.5, true);
  } else {}
  bucketHor.y = after;
  bucketHor.x = 300;
  bucketItem.scaleX = - 1;
  var buckettwoTween:Tween = new Tween (bucketItem, "x", Regular.easeOut, bucketItem.x, 0, 0.5, true);
  }
  var bucketImgTrans = new TransitionManager (bucketItem);
  bucketImgTrans.startTransition ({type: Zoom, direction: Transition.IN, duration: 3, easing:Strong.easeOut});})
  var bucketImgTransH = new TransitionManager (bucketHor);
  bucketImgTransH.startTransition ({type: Zoom, direction: Transition.IN, duration: 3, easing:Strong.easeOut});})
  trace (bucketItem.y);

  trace (bucketHor.y);
  addChildAt (bucketItem, 0);
  addChildAt (bucketHor, 0);
  After = (after + 200) - 115;
  1st (1st + 130) = - 50;
  }
  }

  It's the Stmt trace for two position there of bucket

• Prompt the user for a parallel process

  Hello

  I am developing a software where I constantly read data from equipment. There is a command that requires a password to enter in this software. I tried to use the query the user entry to receive the password for the user. However when the guest user screen opens, my software stops the reading of data from the equipment until the user enters the password. I don't want that. I want to read the data coming from the equipment, while the user inserts the password again.

  Is it possible to run the query the user entered a parallel process during execution of the read data part? Is there another way to request a password from the user?

  Thank you for helping!

  Hi Ariyoshi,

  LabVIEW is based on DATA streams. When there is no dependence on the data between segments of code, and then they run in parallel.

  Put your password dialog box in a parallel loop...

• 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?

  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.

• 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.

• Waiting for timeouts in parallel for loop

  Hello

  I am currently working on a project where I communicate with a number of devices over TCP. This happens at the same time, which is not a problem as long as does not change the number of devices. Now, I want to open my project to support the case with different numbers of hardware devices, which I want to make a loop (read the device of DB information in an array and iterate over all items).

  I read on a single loop parallel execution for, but it seems that the logical cores is a limiting factor for the number of alternative treatments. Unfortunately, I must also take into account delays in communication which translates as the waiting time for each iteration of the loop.

  As you can see I have this creates a lot of idle time that adds up quickly (running with 10 carrots 4 logic devices takes three times the delay to finish without the loop it would not delay time as all connections are pending at the same time.

  I hope someone can direct me to a solution.

  Thank you

  Move the reference VI opened in the first LOOP.

  You use the same reference for all instances.  So wait for asynchronous call will just see one of them finished and the results.  By placing the reference VI open inside your loop, you will have a different reference for each call of your VI.

• 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).

• Can we use DBMS_JOB for parallel processing?

  Hi all

  I wonder if we create 10 jobs each inserts 100 rows in a specific table. Will it be parallel? In other words, please correct me if I'm wrong, when a job starts Oracle does not wait for it until he finished. It run other respectively, right? If this logic is true, then we can use DBMS_JOB and DBMS_SCHEDULER for parallel processing?

  Thanks in advance.

  Yes, you can use these 2 packets for parallel processing. I suggest using DBMS_SCHEDULER instead, because it is much more powerful than DBMS_JOB. I noticed a kind of latency using DBMS_JOB between the presentation of each batch.

  I usually combine DBMS_SCHEDULER with DBMS_ALERT to acknowledge the completion of the work.

  As suggested, you can also use DBMS_PARALLEL_EXECUTE. This package uses the dbms_scheduler logic.

• For loop within a while loop

  I have for loop within a while loop... admission to the for loop N comes from the VI selection... the while loop I a condition essentially statement it stops just after to finish all the iteration in loop...

  Entrance to the N loop is bascially driven by a local variable... that's the problem Iam having:

  When I press the Start button to run the program... regardless of the output of the select VI is gives the N of the for loop, then the loop starts and then ends in place... and when the output of the select statement takes a different value (the N of the loop for) loop not work until I restart the program again... What can I do so that the for loop runs again for another value of N, the RUN program button is enabled.

  1. clean your diagram.  Style guides suggest keep the pattern of a single screen.  With a little effort, I was able to get your DB less than 1600 x 1000 pixels.

  2 then I can see (some) it happens all at once. This thing does nothing?

  3. local variables can lead to race conditions.  Output in Angle position may be a race condition, although is probably not what you wanted to do.  What does the wired local time at the moment present terminal meter? (Ooops! Two controls with the same name - which can be quite confusing as well!)  If you need or want two components of façade having the same text, use the legends.  Make the labels is different so the comic is more readable.

  4. having more than one Dequeue function on the same queue will lead to unpredictable results.  When an item is removed, it is removed from the queue and is not accessible to any other Dequeue function.  In parallel loops, you have no way of guessing which Dequeue will seize any particular element.

  5 use Boolean reverse instead of Select with wired False to true and true cable at the entrance to false entry. Better, just make the case of forgery in the structure of the case within the for loop the real deal. No required reversal.

  6. I was not looking for to determine the logic of the code within the structure of this case. It seems I could have posted a much simpler way to do this several weeks ago.

  7. use multiply from the Digital Palette rather than a node form multiply by 4 or 1.8. Uses less space BD and is much easier to read.

  8. as has been suggested, learn how to work the machine architecture and the State of producer/consumer.  They can make your life much easier.  Do not try to convert immediately to these models.   It's too much bite to at some point.  Learn how they work first.  Make a few simple examples.  Then rewrite this program in this format.  Probably faster than fixing what you have now.

• Parallel processing in ODI

  Hi experts,
  
  I have 30 + files in text format, that contain the partitions of the same table. These partitions can / must go through the same parallel processing and must then be added to one big file.
  
  I would have no problem in designing the transformations in ODI (since I have the SQL code), but I'm looking for "elegant" way solve the problem. By elegant I mean modular, with minimal work replication, etc.
  
  Thank you very much.
  
  Joan

  1. create a dummy data store in ODI with column structure imitating the structure of your file under file template
  2 duplicate this data store in the Oracle model.
  3 duplicate the LKM file to oracle using the charger and modify it so that the two target table and data path/file come from options KM (add these options if they are not already).
  4. develop an interface with these data banks and new LKM. Use an IKM that makes a straight line create a target table and load without worrying about creating I$ (IKM SQL append seems ideal, but you may need to change in order to ensure that the target table is variable). Use two variables (var2 and var3) to specify the new options in LKM (and if necessary IKM).
  5. create a scenario.
  6. create an Oracle table that contains a sequence, the target_table_name and the source_file_with_path.
  7. create a package, which defines the variable (say var1) to 1, use two other variables to store target_table_name and source_file_with_path based on var1 and call your scenario. Check for error and success, var1 and loop increment.
  8. in the end, create your large table with partitions and write an ODI procedure to loop through the tables to the target and make a partition change.

  This is the more modular approach, I can think.

• Some performances are not completed to help put an end to everything in the model of parallel processes

  Hello

  This question confued me recently, I would use a parallel process of model and to finish running at the same time.

  If there are action steps in order, it seemed that will put an end to the execution of all.

  However, I put a wait instead of steps of the action function, there are a few executions not interrupted while I pressed the button finish everything in the toolbar.

  Hope someone can give me help. Thank you very much.

  PS. the number of testsockets has the value 9 in my teststand.

  I ran your sequence again, and I have reproduced the issue.

  It seems the action of the polls Test for success/failure of the VI at full speed.

  It will consume your CPU resource to 100%.

  So I add some delay in the VI to prevent election full speed.

  Please see the following block diagram.

  

  I tried and it seems resolved the problem.
