• How to measure the execution time of a specific to a VI process?

  Hello! My VI has two processes: compression and edge detection image and I'm trying to measure the execution time for the process of detection of edge of my VI, but I don't know how to do. Please give me some ideas on how to do it. Thank you!

  There are several ways that you can do.

  -L' one is using the number of cycles before and after your vi to get time like here: http://digital.ni.com/public.nsf/allkb/6F6B9F4E149C80578625652800784764

  - or use the profiling: https://zone.ni.com/reference/en-XX/help/371361H-01/lvhowto/profiling_vis/

  Edit: If you're open to suggestions:

  -You have not to load the image inside the loop instead, make him outside of the loop.

  - And I see of many IMAQ buffers are not removed properly. You can have everything at once by Images (No) by logging in to Boolean TRUE: http://zone.ni.com/reference/en-XX/help/370281P-01/imaqvision/imaq_dispose/

• How to shorten the execution time of the NXT (TETRIX & MATRIX toolkit) brick

  Hello

  How to shorten the execution time of the NXT brick?

  Hi 40123157,

  You use the module in an appropriate manner, and there is no simple way to improve the time of loop iteration beyond what you've done. Here are my suggestions:

  (1) the i2c commands take a long time. In your application, it may speed up if you run only move the engine only when the engine speed has changed.

  (2) for this particular example, you do not use the release of the report engine. If this VI does not need to run it can be removed.

  (3) If you need to speed up execution other than that, as a user advanced LabVIEW, you can create a copy of the VI of engines to move and change it as you choose. All you have to to the "DC motors' entry is use cluster to array on the cluster, as shown below. I think you can speed it up by running all the settings before the loop (type sensor and fixed connection configuration), and removing the value of power if you send only the values between-100 and 100.

  (4) drawing on the screen can be slow you down here.

  

• How to calculate the execution time of a SCTL in FPGA VI?

  Hello

  Can someone guide me that how to calculate the execution time of a SCTL for an iteration in the FPGA VI?

  Thank you and best regards,

  Rashid

  Hello r,.

  A SCTL will always run in a beat the clock it has been linked to.  So, if you use a 40 MHz clock, this loop will run in 25 ns.  If the code cannot complete in that, or if it requires two graduations of the watch to do the calculation, your code does not compile, then you have the guarantee that this will always be how long it takes this piece of code to run.

• Why the execution time increases with a while loop, but not with "run continuously?

  Hi all

  I have a problem of severe weather that I don't know how to fix it because I don't know exactly where it comes from.

  I order two RF switches via a data acquisition card (NI USB-6008). One job at the same time can be selected on each switch. Basically, the VI created for this feature (by a colleague) resets all the outputs of acquisition data and active then those desired. It has three entrances, two chain simp0le controls and a cluster table, that contains the list of all the outputs and some practical information to know what is connected (specific to my application).

  I use this VI in a complex application, and I have some problems with the execution time, which increased whenever I said the VI, so I did a test VI (TimeTesting.vi) to determine where the problem came. In this special VI I record the execution time in a csv file to analyze then with excel.

  After several tries, I found that if I run this criterion VI with the while loop, execution on every cycle time increases, but if I remove the while loop and use the funtionnality "Continuous run", the execution time remains the same. In my high level application, I have while loops and events, and so the runtime increases too.

  I someone could explain to me why execution time increases and how can we avoid this? I have attached my VI test and the necessary subVIs, as well as an image of a graph that shows the execution time with a while loop and «run permanently»

  Thanks a lot for your help!

  Your SetReset_DO VI creates a channel whenever it is called.  And that you never delete a task.

  When running continuously, that it's as if it only runs once and LabVIEW has internal mechanisms to close references that will not be used again.  When a VI is used as a Subvi, LV does not know if she will be called again, and lacks these things until the first level VI stops. You have a memory leak.

  Just as you open and close your file outside the loop for, create your channel out of the loop.

• After installation, I can't find the execution time

  It sounds ridiculous.  I produced an executable with Installer (2009) and install it on a pc and everything worked fine.  Now, I tried installing on a 2nd pc, and although N.I. Run Time files are obvious, can't get the button to push to get the run-time operation.  Is there a main file I should be by clicking on?

  I'm curious, what exactly is your problem?

  The system requirements for PSE14 and ss14 requires Quick Time 7 on Win or Mac.

  I just checked that I had not installed on my PSE14 on 10 to win Quick Time 7. No problem, but I rarely videos, and I have other viewing software like VLC media player.

  Just out of curiosity, I installed Quick Time 7 without problem.

  Wouldn't be a problem with Premiere Elements or Mac?

• Resource plan in order to limit the execution time

  Hello
  I use 11.1.0.7 database. Can someone guide me how can I create a resource group resource consumers plan and assign them to my user "dev" so that any query that is run by this user shouldn't take more than 10 minutes for execution and must be abandoned if the execution time exceeds 10 minutes.

• How to know the execution time of query in sql plus

  Hello
  
  I want to know the duration of execution of query in sql more accompanied by statistics
  
  I say time is set on;
  Set autotrace on;
  Select * view where usr_id = "abcd";
  
  
  If the result is 300 lines it scrolls up until all the rows are retrieved and finally gives me the run time in 40 seconds, or 1 minute... (it is after all records scrolls)
  
  but when I run it in Toad he gives 350 milli seconds...
  
  I want to see the execution time in sql how to proceed
  
  client and database server 11g is g 10

  In sqlplus you can do set autotrace traces to suppress the display of the selected lines.

• Get the response time more with First_Rows Hint.

  Hello
  I use 10.2.0.1.0 oracle version. I have a sql query that gives performance with cutting-edge FIRST_ROWS problem.     I expect the best response time with suspicion of "FIRST_ROWS (5)", but his is the worst, with use of a different set of the index, which is local to the partition. Please, help me to understand, the reason behind this change in negative execution path?
  

       First query gives all the ~3488 rows within ~1 minutes but the query with HINT is taking ~15 minutes for providing initial few rows itself. 
  For second one i am not able to get the exact and estimated cardinality stats , as it was taking lot of time for completion, so providing Autotrace plan only.

  Yes, Jonathan, in fact in the first case, i 'I' table is being analyzed using an overall index, but suspicion FIRST_ROW sound using the index that is local to the partition. resulting in the digitization of all partitions of 448. I think it's causing bottleneck. Is there something like: FIRST_ROW suspicion that affect this type of systematic index scan?

  In the first case the optimizer has unnested subquery of REACTION and used to bring to the table, I, and that's what dictated the choice of index.

  In the case of first_rows (5) decided that the range index scan will take adequate data if some time he chose a different index - running subqueries in the REACTION as a subquery for filter on each line. But it is the estimate of how long it will find adequate data (and how much time he will have to run the subquery to eliminate unnecessary data) does not.

• Get the response time data VI

  Hi guys,.

  I am trying to use CD get time response data VI my VI. When I choose the pair of input-output, I can get the response data determined by the digital input to the output value. However, I need more of a pair of response data. I try to use the list of input-output, but there is no output data and response time of the VI with table 1 d of numbers.

  My question is how to use the CD get time VI data response with the list of inputs-outputs configuration? Thank you.
