TDMS write memory and VI a remake TDMS API - LV2009

• TDMS write memory leak

  I use TDMS to store test data that seems to be causing a memory leak in my (very convincingly) program. Below is a graph of the three versions of my program. Series 1 uses storing data open PDM, the data file added and closed every 5 seconds. Series 2 uses storing data PDM with a referense remaining open during operation and closed at the end 3 series written data in a CSV file. The charts show the use of LabVIEW memory each seconde.5 ~ 4 hours of a 10 hour test.

  LabVIEW 8.6.1

  Windows XP SP3

  

  Further explanations... when a TDMS file is opened, LabVIEW will create an index in memory structure that is used for random access to the file. The Streaming API integrated LabVIEW TDM will always create the index, even if you just write. The size of the index is not dependent on the size of the file, but on how fragmented file is. If you store a relatively small number of large blocks of data, the index will be very low. If you keep adding small amounts of data on your record, it could make big enough. A cure for this is the property of NI_MinimumBufferSize. You can set this property on a channel to the LabVIEW to a number of values of the buffer before storing. In this way, data from multiple calls to 'Write TDMS' counts as a data segment in the file. Typical values for this are 1000 or 10000. Fragmentation of files and memory footprint are reduced accordingly, but LabVIEW uses little memory for buffers.

  If all else fails and you do not have access to the file of reading while you write, you can also use the VI-based TDMS API. This will not build the structure of the index that I mentioned above, so there should be no increase in memory at all. In this case, I recommend to defragment files front of post-processing.

  Hope that helps,

• Sat Pro 2470 memory and BIOS update

  I recently received from Win XP SP 2 installed on the laptop and the free memory is very low (64 internal, additional 64 installed)

  I would like to add 2 x 128 MB to 320 MB total authorized under the current BIOS.

  After doing this, the manual says in Chapter 8 on page 7 that some files must be removed by following these steps:

  Click Start, and then turns off
  Brand to start the computer in MS-DOS klik OK

  Write to CD\Windows - renterb]
  Write the output - enter

  With XP, I can't find the option to choose start in DOS at the next startup. Is this also necessary when I add memory?

  Question: why should the battery be taken out when changing the memory? Isn't out enough power?

  WE BIOS: I can't find any information on what brings the BIOSupgrade available for this laptop. If I update the BIOS, which is the maximum size RAM and HARD drive? All the other important points?

  Hello

  I don't think that you should remove all files with Windows XP.
  Simply insert the modules of memory and power on the machine.
  Updated the BIOS normally does not increase the available memory.

  Good bye

• How to create a file in memory and then store it in the database

  Hi guys,.
  I wonder how I could create a file as plain text or css styleshhet in run mode and then store this file in the database. I need to save in the cause of database application doe doesn't have permission to write to the file system.
  Is this possible? A file can be created only in memory and saved in the database instead of the file system?
  I would appreciate your help on this.
  Thank you very much.

  Anyway, you cannot use the link tag to load the style sheet, because you do not have the file, you must set the css within the jsp (using the style tag or whatever it is).

  Hope that you do not build a serious application in this way.

  Actually, you can if you use a URL to a servlet that serves as the stylesheet directly from the DB.

• How to take movies on my macbook air to free up memory and still access those I downloaded from iTunes?

  I want to free up the memory on my macbook air and have 65 GB of movies hogging the space. I don't want to lose them forever if you want to know how I can free up memory and again back to the film at some point in the future.

  If they were purchased through iTunes, you can download again them at any time.

  However, there is no way to stream movies, so you have to download the entire file again for a movie.

  Open iTunes > iTunes Store > purchased (on the right side of the window) > movies.

  Make sure that the sort is set to "Not in my library" If you try to redownload something that has been removed from the computer.

  It depends on what Mac model you have and is not possible for all models. Go to the website of OWC or Crucial and check.

  See:

  Get only the memory of a place as above, since Macs are picky about the memory. Another place is crucial.

  If you can't swing for 16 GB (2 X 8 GB) replace a strip of 2 GB with a key of 8 GB.

• Memory and disk HARD upgrade question - Satellite 5200 801

  Hi all

  I really need your help to upgrade my toshiba Satellite 5200 801 (model: PS520E-31P1D-EN), basically it's the version specification factory (technical instructions on the link below)
  http://www.cwrose.de/Toshiba/S5200.html

  What I want is to get faster internal memory, you can buy for this model (currently I have two default 256 mb DDR 266 MHz CL2.5 memory sticks). Will probably do a gig of memory (I could have more, but it depends on the price).
  As well, I want to spend the HD to 160 gig (about), as well as get a faster hard drive then the current 60gig 4200 RPM Hitachi HD (as soon as possible for the specifications of my laptop).

  Anyone know what would be the best option?

  Someone said that it would cost all under 100 (that would be cool), but I don't know anything about the compatibility of different companies etc.
  Can anyone recommend what equipment... .and where * I hope that ebay or studs :)
  I need to go to get this sorted out

  PS:
  FYI, I mostly use the laptop for graphic design, video, and the interwebz.

  Thanks for any help you can give!

  Hello

  You can upgrade the Satellite 5200 801 memory and HARD drive.
  S for laptop computer memory can be improved up to 1 GB of RAM. So you can use 2 x 512 MB PC2100 DDR - RAM modules.

  Check this link 5200-801 Satellite:
  http://www.orcalogic.co.UK/ASP/ProdType.asp?ProdType=6116&ft=m&St=3

  In my opinion, you can use the modules of memory from different manufacturers, but the module must support these specifications: 200-Pin PC2100 (266 MHz) DDR SODIMM
  I suppose you could also use a 400 Mhz because the laptop supports a 400 Mhz FSB too.

  I think that an upgrade of the IDE 160 GB HARD disk is not possible. To my knowledge, the BIOS can support such massive size of the HARD drive. But this is only my personal opinion. If I was you I would try a smaller HDD like 100 GB or 120 GB.

• Can I change the new memory and at the same time to replace the Rams?

  Can I change the new memory and at the same time to replace the Rams?

  If a MacBook Pro RAM and drvie hard can be modified/improved depends on the submodel and we do not know yours. There are dozens of variations of the MacBook Pro issued since 2006, and you do not want guessing us!

  Please do "about this Mac" in your Apple menu to get this:

  

  Notice the line that I have highlighted with the red arrow. Please tell us what your computer has in the thr same place. However, do not post any serial number.

  With the exact submodel we can better advise you of any available upgrade paths.

• Can I replace the memory and not lose what is on the old memory for a Mid 2007 Mack computer desktop Intel Core 2 Duo, 2 GHz processor speed, 1 CPU, 4 MB of Cache L1, the 4 GB memory at 800 MHz bus speed.  Only 1 slot can play memory, the other is damaged

  Can I replace the memory and not to lose what's on the memory of the former?  I have a Mid 2007, 20 "desktop Mac, Intel Core 2 Duo, 2 GHz processor, 1 CPU, 4 MB L2 cache, 4 GB of memory, 800 MHz bus speed.  I have a backup device.  A RAM slot is damaged.

  You are confused of RAM and disk space available.

  RAM stores information temporarily while the Mac is enabled and the application is reached. RAM replacement has no effect on the long term of your information storage.

  The hard drive is where your information is stored in the long term. If you replace your hard drive, you need restore the information from a backup.

  FYI, for your iMac, the maximum RAM is only 6 GB.

• Extension of memory and HDD on Satellite 1805-s203

  Satellite 1805-s203
  Intel Celeron 800 MHz
  128 MB expandable to 512 MB
  15 GB HARD DRIVE

  I recently installed at 256 MB of memory and it seems that the memory slots. To develop my memory 512 MB what should I remove the memory of 128 MB and replace it with a 256?
  Addition, how else can in I put this laptop? I could increase the HARD drive? How could I increase it with 512 MB of memory?

  Hello

  It is not easy to find specific info on older models of laptops. According to the mobile news it can handle with max 512 MB of RAM. Compatible RAM module is KTT-SO815/256 256 MB memory-(Kingston). With the help of two of them you can have max RAM and laptop will go much quicker.

  Disk HARD is not easy to say with certainty, but I think that you can pass to 30 or even 60 GB, but 30 should not be a problem.
