Cost of the memory of SubVIs

I have explored various options to reduce the consumption of memory in my LabVIEW applications and read a lot of threads on the forum and NO help/tutorials on the subject.

I noticed that when I generate a table in a Subvi it creation in my VI apparently cost me 1.5 times higher level memory allocation? I guess it's to do with the use of the indicator on the Sub - VI (which I need to transfer my data from sub to main VI VI), but I thought subVIs shouldn't have such an additional memory of costs.

I have attached two screws that I used to do a test. Just steps to the test in the face before of the main VI. Basically, I used Windows Task Manager to determine the consumption of memory during initialization a 3D Board first in the Mian Vi and then using a sub VI. I have found that the main method of VI consumed approximately 15.7 MB and the sub VI consumed method 23.5 MB.

Could someone explain the cost of additional memory and how I might be able to avoid when using sub screws?

Note: I've only used the concept of initialization for example. What I really want to do here, is to get my head around the areas where my LabVIEW applications consume memory and reduce the memory if possible cost.

If you go into the properties of VI for the Subvi there should be an inline option by calling the screws on the performance page.

This will eliminate the overhead of the call to the Subvi (do as if the Subvi code were part of the main VI).

Also, make sure that you have disabled for the Subvi and the main VI of debugging.

  • Advice/cost for the upgrade of MacBook Pro memory

    I have a mid-2009 13-inch MacBook Pro. It has 2 GB of RAM and I want to update 8 GB of RAM. I heard it is expensive to have Apple install memory, but I really do not trust myself to install it alone! Does anyone have an idea of what it would cost (for the work of Apple and memory) for this upgrade? And if no Apple, anyone have any suggestions for qualified but cheaper alternatives? Thank you!!

    Dailey,

    You can upgrade RAM yourself at a reasonable cost.

  • Compilation of FPGA - real formal error on the cost of the port cannot be an expression

    Details:

    The compilation happens to step "using the unit felt" but then stops soon after with a compilation error.

    The line in question (1408) refers to the output of a "Reinterpretation FXP" node with the text

    Cost => (others-online '0'),

    in the part of port of the code card.  This is the output of the FXP reinterpret node is directly connected to an indicator in a VI sub whose output is then entered directly at a crossing high multiply node.  The code is part of a cosine sine LUT I programmed.  She used to compile without a problem, but I think I know where is the problem.  In one case, I have used only the sine of output of the algorithm and theory, Xilinx can optimize away from the part of cosine.  I have two instances of this VI in my code and looking at those generating any errors, the output is associated with a cosine indicator.

    Cost-online s_Cosine_2434,

    It seems that the track is essentially optimized away, but the compiler, Xilinx has a problem with the flag being present on the sub - VI but the idnicator is not used anywhere.  As a result, the cost gets set to an invalid value.  I guess close to reinterpret it FXP at the exit of the Subvi is an important aspect of this problem.

    I think I know enough now to fix this (remove the path manually by duplicating the sub - vi), but it may be useful for future bug fixes feedback in the FPGA module.  It is not the first time that this kind of removal of incorrect code me has given problems, but this is the first time I could clearly identify the problem.

  • Use of the memory of blackBerry Smartphones

    I'm a little red faced.  But thanks for the instructions to the new Message.  I'm new to blackberry.  I have a lot of emails between different accounts.  This is my first experience with the receipt of e-mail to a "mobile phone".  I have checked through earlier assignments and know that my options are set for 30 days.  All these messages with attachments that have been opened are beings stored on the device memory?  It seems that I'll take five to 10 messages at once, or at least when I check, and I have not the time to remove a.  I also know that I can delete multiple messages as soon as possible.  Please, don't think it's crazy, but I hope that tolerate the elderly, it seems that if I just ignore these messages that I don't want to not display on my blackberry, stored in a bunch?

    Hi and welcome to the Forums!

    There are three types of potential memory on a BB: 1) application memory, the device memory) 2 and 3) Media/SD memory card

    Application memory - it is the most important; It is protected (not available to the user), dedicated and (fixed size) space as the destination for the installation of applications (more a few storage applications, overhead and other costs). You can't touch AppMemory. You cannot improve the maximum AppMemory that your BB has. It is what it is. Applications can install only here... There is no other choice.

    The device memory - it is space on your BB you can touch these files, images, media, etc. In general, it is not very big, but it is available.

    Memory card SD/Media - is what it says... your SD card to store files, media, photos, etc.. It can be as large as your BB OS can support... see this KB:

    On some devices/OS levels, enforcement and the memory of the device are combined into "free file"... This is, IMO, a little more difficult to administer that you can't see really how AppMemory you have. Nevertheless, here are some tips to use:

    In addition, it is always important to correctly close applications when you are finished with them. Using the back or on the red button won't do that - those leave the app to decide what to do... and some let themselves memory-resident, consumes resources on your BB, slowing down the overall performance. Rather, to close an application, press the BBKey and select 'Farm' or 'Quit'... that forces the application to be closed, freeing for your new use the resources it consumed. Some applications will always be running (in general - BBMessenger, browser, homescreen, phone and Messages)... but, you should always close them properly - especially the browser... If we leave on a web page, it will not consume only additional resources, but the power of the battery as well.

    Now to your question... Yes, if you do not erase the messages, they take place on your device. But wherever we consume is more delicate than what I described above (there are a few other places of memory... but I did not fully understand those!). Basically, if your device starts running out of space to store messages, it will start delete 'old', even if the timer you have set has not yet expired on these points. It protect themselves first, then try to keep things for you.

    As for the attachments... I don't think not that those who download, unless you open in fact the message and then again to open the attachment,... so, if leave you a message without opening it, the only storage that it'll take is the bit of the message itself... the attachment occupies no space if you don't ever get it.

    Good luck!

  • Confusion over the memory of a bunch of Java and WLS_FORMS

    Hi all

    Background first:

    Oracle Forms/Reports 11.1.2 64-bit
    WebLogic Server 10.3.6
    JDK 1.6 update 37 64-bit
    Microsoft Windows 2008 R2
    Using nodemanager to start/stop the servers managed

    After reading all the documentation and searched this forum and the Internet for advice, I'm still totally confused about how best to make use of memory on the server (the server I'm working now on a 8 GB). Two trains of thought that I discovered in my research:

    (1) do not change the size of Javaheap at all (stick with the default values) and just create additional managed servers on the same machine.

    (2) increase the size of the heap Java for WLS_FORMS

    That said, here are my questions:

    (A) what is the best practice approach (#1 or #2)?

    (B) if it is the #2, what is the approved way to increase the heap size? I tried to add - Xms and arguments - Xmx to the WLS server begin arguments in the WLS console. They are applied when the managed server is started (confirmed in the log file), but because of the way WLS_FORMS is started, there are more - Xms and arguments - Xmx applied after mine, and peaks of Java one last mention if there are duplicates.

    1st update: Question #2 seems to be answered by the support notes 1260074.1 (the only place I had not yet looked at)

    Thanks for any idea that you can provide. If there is a document that I missed somewhere, I'm happy to be told where it is, and will read and summarize the results here.

    Kind regards

    John

    John,

    I'll try to comment on each of your own:

    (1) we had been make some type errors "Unable to contact forms Apache Server" (users see the error "Failed to bridge APACHE server"). The logs showed nothing interesting. I increased the memory allocated using setDomainEnv.cmd, and the error seems to have disappeared. Yes, I know it's a shotgun approach, try something without really having a reason to do it, but it seems to have helped Edit: now I have review of OHS logs instead of WLS_FORMS newspapers, I found the log messages, which brings me to Doc 1380762.1, who tells me that I need a patch. DOH. Oh crikey, forms 11.1.2.1 is out and it came out shortly after that we have downloaded 11.1.2.0 to create these environments. Good and the bad new kind of thing...

    The Apache Bridge error is relatively in line toward the front if you understand what it is say you. It is an error generated by mod_wl_ohs which is the property of SST (Apache). This module is responsible for the relationship between OSH and WLS. The Apache bridge error means that OSH (mod_wls) has been unable to get a response from the managed server WLS he called. Basically, he was unable to cross the bridge ;) The cause could be anything from the managed server does work not, management server is busiest, or there is a problem of network configuration and the server simply didn t hear appeal of OSH.

    It is all described in Note 1304095.1 MOS

    Regarding 11.1.2.1, this can be installed fresh or as a patch on 11.1.2.0. So for machines which currently installed, you can go directly to 11.1.2.1 without having to first install 11.1.2.0.


    .

    (2) as tony.g suggested, we are looking for what we should do to solve them "I have n servers with x GB of RAM, what should I do to configure out-of-the-box forms for stability" issue.

    As I said, there is really no 'forms' specific settings associated with how much RAM your machine has. The only exception to this is (although a little indirect) to use the grouping of the JVM. JVM pooling can reduce the size of each execution process memory footprint by moving his calls from java to the pool of the jvm, then common queries of sharing with the other running execution environments. Memory, use of OSH or WLS managed server really has nothing to do directly with the forms. Specifically to the managed server, from a perspective of forms, I would not expect the cost of memory of WLS_FORMS spending a large part due to the workload. I'm expecting increase as the simultaneous load increases, but I would not expect it to be significant. If I had to guess, see an increase of 1 m or less per user wouldn't surprise me (that's just a guess - I don't know what would be the expected values). If we were to use our older scalability guidelines (Oracle), usually we would have suggested that you should consider about 100 sessions by 1 FMV for better performance. Given that v11 uses a newer version of java and scalability is better today, I suspect that you can easily spend a couple of hundred (300 for example) or more before the performance decreases. In addition, the need to add more managed servers would be probably necessary.

    This is discussed in Note 989118.1 MOS


    .

    (3) HA is important to us, so we set up a cluster of servers of forms/States with a BLT in front of her. I read in the literature on the management of clusters, cloning of a managed server and with the support, how to increase the memory heap for the WLS_FORMS server. My thought process was 'If Oracle gives me instructions on how to increase the heap memory and how clone managed servers, there must be a scenario in which do have advantage." I'm trying to understand the scenarios in which we would do either of these activities.

    Refer to the note that I mentioned above. As a general rule, if you limit the number of simultaneous sessions less than about 300-400, I think the default settings should be fine. If you think you want to go beyond 300 or 400 per managed server, then probably you need to increase the heap the managed server max. Yet once again, refer to the note that I mentioned earlier.

    See also Note 1260074.1 MOS

  • New on Apple computers - Question on the use of the memory (RAM)

    Hello

    I recently bought a rMBP 13 "with 8 GB of RAM. This is only my third time (I started for the first time last night). Here is a screenshot I took of the memory usage after starting it on for the first time. My question is: is it normal to see that most of the memory is in use, even if I only have Safari (1 inactive tablet on the homepage of Google) and open the activity monitor? I'm afraid that this is rare and not have a lot of wrong answers online.

    Second question, if someone has knowledge: 8 GB of RAM is good enough to run software such as MATLAB, AutoCAD and SolidWorks? Or 16 GB would be better? I still have time to exchange the rMBP.

    ElCapitan is designed to use as much RAM as possible at all times for efficient operation.  She will move to a video buffer, operations of common files, etc. in the RAM and the y keep in case he should run again.  CBS will move embusked operations out of RAM if new operations is displayed.

    As for "enough RAM for your planned tasks", 8 GB might be enough, given the fast read/write of the SSD and the very fast moving data in the SWAP file on the SSD.  But if you have any doubt, you have 14 days to return without any doubt and re - buy a Go 156 system.

  • Mac problems due to the memory

    I have problems with my Mac doesn't turn is not on. He turns sometimes and sometimes does nothing for days. I've read a lot online, and it seems to be the memory of the origin of the problem.

    When it's on I went t disc utility and of course there are 499 GB 500 GB used. I started the trash everything. I got up to 310 GB of used memory, but when I click in disk utility there are two levels of "Macintosh". Level 1 - logical volume memory I think it was called is still at 499 but the second level which I believe was called simply logical memory is 300 GB.

    I live in Tasmania where there is no official Apple store and authorized service location is closed on weekends so I'm pretty stuck for a few weeks before I can get down to one.

  • Satellite M40x - where the memory?

    Hi all

    I want to improve my memory of 512 MB to 1.5 GB. I bought 1 G RAM and when I plugged in the screen become white and computer laptop does not work. RAM is fine. I have contact the technical service of the seller, and according to them I need to remove the old 512 MB of RAM and plugged it my 1 GB of RAM for my laptop recognize the new RAM.

    To do this, I opened my keboard and under what I can only find WLAN in the middle in the left there is another local network. and the far left, I see my DVD - ROM. On the right PC card and what is - this. I don't know where is the 512 MB RAM slot. It is there somewhere.

    Is there any expert who can tell me where to find 512 MB RAM slot?

    PS: I even call Toshiba support and they said sorry according to policy, we cannot tell you.
    If expert laymen captions please help me to solve this problem.

    Please

    I checked the manual of the Satellite M40x (it can be downloaded from the Toshiba site) and if you look at page 8-7 you can find a description of the memory upgrade.

    In my opinion the 512 MB that you already is a built-in RAM that can t be upgraded because the bottom of the laptop is on only one memory slot.

    However, I think that it is not a problem to use an additional RAM module, but maybe the new RAM is not compatible with your laptop.
    What type of memory you have bought exactly? Maybe you should try it with another.

    I hope I could help a bit.

Maybe you are looking for
