Why is the synchronization statistics are not Performand and memory profiler?

Hello

I have a Subvi, which I have timed with a stopwatch to 88 seconds, and the Profiler is telling me that the total time is 20 seconds.  The Subvi is activated by a button, contains a loop for, and is the last action in the program.  Everything is always changing as expected - if I reduce the number of iterations inside the Subvi loop for by a factor of 10, I can measure and 9 seconds with my stopwatch and the Profiler tells me 2 seconds.  What is going on?  Why is the Profiler to offshore?

Ken

Ken,

AVI playback has a period included widening due to the framerate of the video that you read. If the fps (frames per second) of the video is for example 30, you have to wait between two images 1/30 s = 33.3 Ms during this time of waiting, the Profiler does not show the appellant as active VI. The caterpillars needed time by calling contains only the loop and the call to IMAQ AVI reading Frame.vi. No time the Subvi takes.

If you look in the time taken by IMAQ AVI frame of reading, you won't see the "wait time", as it is once again a function called by this VI...

hope this helps,

Norbert

  • I have an email stuck in my vision of the box. Are not sent and cannot be deleted. How he get out of here.

    He has been there 3 days.  Systems turned on and turned off several times and as e-mail remains in the Outbox.

    You don't mention what email program you use. If Outlook Express check for working offline and deselect the preview pane and see if it will remove this way. If this is not the case, the sending, or sent items box is corrupt.
     
    Proceed as follows for the Outbox and if the problem persists, repeat for the sent items after you move the messages you want to save to a local folder that you create.
     
    Tools | Options | Maintenance | Store folder will reveal the location of your Outlook Express files. Note the location and navigate on it in Explorer Windows or, copy and paste in start | Run.
     
    In Windows XP, Win2K & Win2K3 the OE user files (DBX and WAB) are by default marked as hidden. To view these files in Windows Explorer, you must enable Show hidden files and folders under start | Control Panel | Folder Options icon | Opinion, or in Windows Explorer. Tools | Folder options | View.
     
    With OE closed, find the DBX file for the folder in question {Outbox.dbx} and delete it.  Another will be created automatically when you open OE.
     
    General precautions for Outlook Express:
     
    Do not archive mail in the receipt or sent items box. Create your own user-defined folders and move messages you want to put in them. Empty the deleted items folder daily. Although the dbx files have a theoretical capacity of 2 GB, I recommend all a 300 MB max for less risk of corruption.
     
    Information on the maximum size of the .dbx files that are used by Outlook Express:
    http://support.Microsoft.com/?kbid=903095
     
    After you're done, followed by compacting your folders manually while working * off * and do it often.
     
    Click Outlook Express at the top of the the folder tree so no folders are open. Then: File | Work offline (or double-click on work online in the status bar). File | Folder | Compact all folders. Don't touch anything until the compacting is completed.
     
    Disable analysis in your e-mail anti-virus program. It is a redundant layer of protection that devours the processors and causes a multitude of problems such as time-outs and account setting changes. Your up-to-date A / V program will continue to protect you sufficiently. For more information, see:

    Sorry, but the live feeds are not saved and cannot not even be found using recovery software because they have not been saved as files.

  • Why the acquired data are not from min to max (DAQmxCreateAIVoltageChan, PXI-4472) values

    Hello

    I'm developing a program for the PXI-4472 acquisition on opensuse 11.4 device (linux 2.6.34).

    I try to acquire analog data and to read in a wav file.

    Configure the task of acquisition with the following functions:

    DAQmxCreateAIVoltageChan(taskHandle,"Dev1/ai0","OnboardClock",DAQmx_Val_Cfg_Default,-10.0f,10.0f,DAQmx_Val_Volts,NULL);
    DAQmxCfgSampClkTiming(taskHandle,"",48000,DAQmx_Val_Rising,DAQmx_Val_FiniteSamps,48000);

    DAQmxDisableStartTrig (taskHandle);

    I don't understand why the data stored in the wav file are not-10V,-10V but-5V, 5V... (the value of the gain is 0dB). (Perhaps a scale of 0.5?...)

    Thanks for your help,

    Questions 1)

    Not because the LRDATA file is fair previews, what LR displays on your screen for a faster loading of the image and will be recreated. The previews only stored in the folder LRDATA is the basic overview created at time of importation for the display of thumbnails and previews of 1:1 for images that you have actually looked in the Loupe View or I guess that appears in the develop module.

    He get all the data to create the image themselves file extracts.

    If you have several files on your system that have pictures in them and you select one of them that you have not looked at in a while, you will notice LR creation of previews for these images, there will be 3 white dots in the upper right corner of the thumbnail. It's LR creation of previews for the thumbnail view. If you scroll quickly in the grid view, you'll notice a few thumbnails of images are gray, until you stop scrolling, then the upper left tile will come in clear view and the white dots will appear on the other images. It's LR creating previews for those of other images. Once LR created the preview of thumbnails that are on your screen, white spot will disappear. If you scroll down again, you will see more white dots

    If you switch to another folder that LR begins again create preview images in this folder. The total number of previews created and stored based on caching of the preview you have in the catalog settings dialog in the management of the files tab.

    If not, you need not the LR Previews.lrdata folder. Whenever LR is not very good this folder with a catalog he recreates it to store previews in.
