Hyperthrea​ding performanc​e

I'm trying to wrap my head around a performance problem that I've been struggling with for quite some time now, as described here and here.
In short, my problem is that my applications, running on Ubuntu 8.04, are significantly slower on certain computers after upgrading from LV8.6 to later versions, while other computer shows a significant performance increase.
I'm now leaning towards this having to do with hyperthreading and the LV compiler. Hyperthreading is one thing that differs the computers (the "good" doesn't use it, the "bad" does), and the compiler is probably the main difference in the LV versions.
Has anyone experienced slowdowns related to Hyperthreading or multicore computers after an upgrade from 8.6? Unfortunately I can't turn hyperthreading off to test my theory.

Well folks, it turns out hyperthreading has nothing to do with the problem. Managed to turn it off and it didn't help, and NI support got the same result. The hunt goes on...

  • I can no longer print pages while using Firefox. Print dings. I can print when in Explorer.

    When I try to print articles, pages, etc. that have the print icon provided, or when I use the File/Print menu, the print options window opens but when the print command is clicked I get a ding sound and no printing. I switched back to Explorer so I could get my work done and the print functions work fine. This problem was just created this week (9/13/10) and prior has been fine.

    Is your printer selected at the top of the native print dialog box ''(what you see when you do File > Print)''?
    If so, try doing the '''reset''' mentioned in this article: <br />

  • AE CS6 renders 7-68 frames out of 889, but gives the "ding" and claims it's done!

    So, I set up my first render with CS6. Nothing too complicated, 889 frames long. I hit "Render" and it starts.
    About 30 seconds later, I hear the "ding," and am surprised to see that according to the program, the render has finished successfully. "Wow," I think, "CS6 sure is fast. A little *too* fast..."
    And sure enough, the render only exported 13 frames! Umm, odd. I check my settings and yes, I've set it to export the entire comp (the Work Area spans the entire comp anyway).
    Okay, strange fluke. Try again.
    7 frames. "Ding!"
    Ugh, try again...
    15 frames. "Ding!"
    And so on... 68 frames. 35 frames. 9 frames. 37 frames.
    What the hell, man! Why does AE think it's done the render successfully, instead of throwing an error? This is completely unacceptable. Obviously I'm not doing anything wrong here, otherwise the number of frames would be consistant.
    When I import the partial renders back into the comp, lay them on top, and export again (to avoid re-rendering those frames), I can get a longer export. So clearly the problem ony comes when there's real work to be done by the renderer, but it never renders more than 70 unique frames each time, and usually I get far fewer, 15 on average.
    This is just stupid, I can't live like this. There's no logic to this problem, which pissed me off so much that I punched a door.
    I've had nothing put headaches with AE CS6 (the new 3D renderer won't initialize with my CUDA GPU, and refuses to fallback to CPU; Dynamic Linking is slower than CS4, etc.), but I've been able to put off troubleshooting these problems so far, and I wasn't worried because there's always an answer out there somewhere, but this is a frickin' showstopper.
    Please help!

    I'm using the default "Lossless" (AVI) settings in the output module, sometimes "Lossless with Alpha" or similar setting. I almost exclusively use uncopressed renders for all my AE projects, as I prefer to use AME or PrPro when rendering out to compressed codecs.
    I've been working with multiprocessing disabled for awhile, so I haven't had to deal with this problem. But I have a moment to breathe between jobs now so I can more fully describe my setup, and run some tests.
    Most (but not all) of my projects have been largely made up of RED footage (r3d files from the original RED ONE as well as Scarlet/Epic), both 1080p and 4K. But I also frequently work with DSLR footage in the dreaded h.264 format (both mpg and mov). Performance within the program itself (including previews) seems quite good, regardless of which codec my layers are made up of.
    For effects and such: some projects have nothing but text layers and masks, while others have extensive keying, color correction, and animation. And some use the 3D ray-tracer and are made up of nothing but shape layers and color mattes, having no video footage at all.
    Since I last moaned about this issue, I have re-installed the CUDA toolkit (instead of just the graphics driver), and now the ray-tracer is working better, and Dynamic Link performance is better, but unfortunately, the problem described in the original post remains...
    When I have Multiprocessing enabled, any render of a comp with more than one layer seems to exhibit this problem. After trashing my preferences, I have been able get a succesful render or two with multiprocessing enabled, if the project is not too complex, but soon after the problem returns for all projects (it's hard to be precise about exactly when, and what project, triggers its return). I have no idea if trashing my prefs has anything to do with granting a momentary fix, or if it's just a coincidence. When multiprocessing is disabled, I generally have no problems of any kind when rendering (other than it being much slower, as expected).
    My system:
    OS: Win7 x64 SP1
    CPU: Xeon E5504 (x2) @ 2.0 Ghz (8 logical cores total)
    GPU: Quadro FX 3800
    RAM: 24 GB
    Multiprocessing settings:
    RAM for other programs: 6GB
    RAM per process/core: 2GB
    Processors reserved for other programs: 0
    Actual background processors used: 7 (this drops when I have PrPro or AME open reserving its own RAM, obviously)
    NVIDIA driver: 301.32
    CUDA version: 4.2
    I can't seem to identify anything unusual about my setup or configuration, and my Multiprocessing settings use recommended guidelines from the AE team (which have proved optimal in the past).
    Is there any other information about my setup that would be useful?

  • Just opened a new blank document in Pages (iWork 2009). When I try to type a letter (any letter of text) the computer just "dings" and types nothing.

    Just opened a new blank document in Pages (iWork 2009). When I try to type any text, the computer just "dings" at me and types nothing.

    Probably you have opened a blank Layout template which requires a Textbox for you to type into.
    Open a blank Word Processing template instead. The two types are listed in the Sidebar of the Template Chooser.

  • Typing yields only "ding" and no text appears!!!

    This can't get any more basic!!!
    New document, typing on keyboard yields only ding sound and no text appears in the document!!!  ***????

    You probably have opened a blank Layout mode template which has no default text area.
    There are 2 kinds of templates, Word Processing templates which flow from page to page and which you can just type into, and Layout templates which require you to create text boxes to type into.
    See the sidebar in the Template Chooser to see which is which.

  • Vibrate instead of ding on plug in?

    This is trivial but driving uscrazy!  I just bought 3 new iPhone 5s.  All identical all running the same software.  We also have 2 others bought 2 months ago.  When you plug in to charge your phone, it makes a "ding" like when you get mail.
    BUT inexplicably one of the new phones does not do this, but instead vibrates.  It is beyond annoying to the person whose phone this is.  She wants to hear the "ding" - she is my boss.
    I have compared all the sound settings and ring settings and I see NOTHING any different on these.  They all seem to be set the same.  It is not on airplane mode, etc.
    Does anyone have any idea why one phone does this while the others do not?  or how to set it to ding when plugged in and not vibrate?  there's no choice of "charging" under Sound choices.
    Thanks!

    Check the mute switch. That's normal behavior if the phone is on mute.

  • When using FaceTime, my iMac makes noises.  It dings like I am receiving an email and sometimes sounds like a busy signal, but this is while I am talking to someone. Any suggestions?

    Dear Mr. Toad (my all-time favorite ride at Disneyland ;-) ..
    Thanks so much for your detailed reply.. my netbook is in the bedroom, turned off.. I (so far) only use it in the evening, in the bedroom.. I've saved your response, and will try your suggestions, and let you know if they solve the problem I described. I really appreciate you taking the time to post such a detailed reply..
    I can't answer your Thunderbird "configuration" questions, because I'm in the living room, using the crap Vista laptop, on which I plan to install Thunderbird, and then take Windoze Mail out in the street and drive over it a few times.. I'll get back to you one way or the other, and let you know if your instructions solved the problem, or not..
    I don't understand why Thunderbird "out of the box", so to speak, simply doesn't forward HTML emails with embedded graphics, (like Outlook Excess, and Winblows Mail do).. without having to go through those steps. I personally HATE HTML email, but over the years, it's become more and more prevelant.. so it's a problem I must fix..
    Thanks again..
    Harv..

  • My iPhone 4s has suddenly stopped making a noise to tell me new emails have arrived, this was after an ugrade to IOS 7.1.2. It worked fine before and I didnt change anything but it just stopped dinging. I have checked Settings-Sounds

    My iPhone 4s has suddenly stopped making a noise to tell me new emails have arrived, this was after an ugrade to IOS 7.1.2.
    It worked fine before and I didnt change anything but it just stopped dinging when I got a new email.
    I have checked Settings-Sounds & Settings-Notification Centre and everything looks fine.
    It worked ok a couple of weeks ago but not after the latest update - anyone know why?

    Thanks Lawrence
    I omitted to say that it only occurs when the screen is locked - if I'm looking at something on my phone when an sms or email arrives, the phone 'notifies' me with a sound but doesnt do it when its screen is locked. Email messages and sms's (texts) still arrive but I get no sound to tell me they have.
    The MUTE swith is in the correct place and I have tried resetting the phone with the Home and Sleep buttons several times, still to no avail.
    I have noticed on the forums that many people are suffering or have suffered the same problem but Apple are never forthcoming, of course,

  • Import and Burn CD Ding When Complete

    How do I turn off the 'ding' notifier in iTunes when an import or cd burn is complete? I can't find how to do this and when I went to the Apple store, the guy at the 'Genius Bar' had no answer. I appreciate any help.

    it refuses to. i have no idea why. i have the latest version. i don't have any other cd burning software.
    just doublechecking something before we proceed. is this the message that you're getting?
    "Warning! The registry settings used by the iTunes drivers for importing and burning CDs & DVDs are missing. This can happen as a result of installing other CD burning software. Please reinstall iTunes."
    ... or are you getting something slightly different? if it's a bit different, what does your one say?
