  • iPhone OS Memory Warnings. What Do The Different Levels Mean?

    - by dugla
    Regarding the black art of managing memory on iPhone OS devices: what do the different levels of memory warning mean. Level 1? Level 2? Does the dial go to 11? Context: After an extensive memory stress testing period - including running my iPad app with the iPod music player app playing, I am inclined to ignore the random yet infrequent memory warnings I am receiving. My app never crashes. Ever. My app is leak free. And, well, the mems warnings just don't seem to matter. Thanks, Doug

  • Which RAM is faster (or, is Crucial's Memory Advisor giving non-optimal advice)?

    - by adpe
    In general, if a PC's motherboard is only specified for RAM up to a given core speed x, will that PC be faster with: RAM of latency y capable of running at a maximum core speed >x or RAM of latency <y capable of running at a maximum core speed of exactly x ? I would have thought the latter, but Crucial's Memory Adviser tool advises the former. So, which of us is correct - me, or the machine? (Here is a concrete example: I wish to upgrade a Toshiba Satellite Pro L300-155 laptop from its current 1GB RAM to 2GB Crucial RAM. The laptop's specifications are given here. I see from those specifications that the laptop is designed for DDR2-667 Ram. Crucial sells two compatible 2GB kits, priced exactly the same as each other: DDR2-667, CL=5; DDR2-800, CL=6. It seems to me that of these two upgrade kits, the first kit would run slightly faster on the L300-155 than the second, because both will presumably be capped at DDR2-667 core speed (see laptop specs), but the second kit has more latency. However, Crucial's Memory Advisor tool recommends the second kit.)

  • How can I find out how much memory an object (rather the instance of an object) of a C++ class consu

    - by Shadow
    Hi, I am developing a Graph-class, based on boost-graph-library. A Graph-object contains a boost-graph, so to say an adjacency_list, and a map. When monitoring the total memory usage of my program, it consumes quite a lot (checked with pmap). Now, I would like to know, how much of the memory is exactly consumed by a filled object of this Graph-class? With filled I mean when the adjacency_list is full of vertices and edges. I found out, that using sizeof() doesn't bring me far. Using valgrind is also not an alternative as there is quite some memory allocation done previously and this makes the usage of valgrind impractical for this purpose. I'm also not interested in what other parts of the program cost in memory, I want to focus on one single object. Thank you.

  • is it possible to load a shared library on a shared memory?

    - by quimm2003
    I have a server and a client written in C. I try to load a shared library in the server and then pass library function pointers to the client. This way I can change the library without have to compile the client. Because of every process has its own separate memory space, I wonder if it is possible to load a shared library on a shared memory, pass the function pointers and map the shared memory on the client and then make the client execute the code of the library loaded by the server.

  • My Android game runs out of memory when it is closed and opened and couple times.

    - by sirconnorstack
    I have an Android game that has an activity for the menu, and then another activity for the game that creates a SurfaceView and Thread to deal with canvas drawing and game logic. When you exit the game and start it up again too much or if you open and close the keyboard (thus restarting the activity), the game runs out of memory, usually when loading a bitmap: java.lang.OutOfMemoryError: bitmap size exceeds VM budget How can I keep all my images in memory without loading them again when the game changes state, or how can I release them from memory and let them reload when the game is restarted?

  • Check if a pointer points to allocated memory on the heap.

    - by Ugo
    Ok, I know this question seems to have been asked many times on stackoverflow. but please read Well the answer for any address is "No you can't" but the question here is to know if a pointer points to a piece of memory allocated with malloc/new. Actually I think it could be easily implemented overriding malloc/free and keeping track of allocated memory ranges. Do you know a memory management library providing this specific tool ?

  • Windows 7 host with Ubuntu Guest and a performance hit, memory locks?

    - by Cyrylski
    I have a brand new Lenovo T510 with Core i5 and 4GB of RAM with Windows 7 on it. I Installed Ubuntu 10.10 in a Virtualbox. For some reason system gets really slow on this setup which makes me really angry. There's a video card shared with full 3D support enabled and 1GB of RAM allocated for the Ubuntu machine. It may sound stupid, but WHY is the whole memory consumed in an instant when I run Virtualbox? I struggled for like 10 minutes restraining myself from a brutal reset, and now everything runs smooth but memory "in use" in Resource Monitor is 3GB flat with only Chrome running. I'm new to Windows 7, but I'm really disappointed with performance at this point... I used to work in a different environment with much slower hardware and there was no such problem (WinXP over Ubuntu, 1GB out of 2GB allocated for WinXP guest on intel GMA). This is, until I clogged RAM totally there. But I was capable of running Chrome, Firefox and Apache server on a 1GB RAM in Ubuntu there and Photoshop CS4 on Windows XP and it worked. In this case I can't go beyond setting up Ubuntu properly. I bet I'm doing something wrong.

  • Very high Magento/Apache memory usage even without visitors (are we fooled by our hosting company?)

    - by MrDobalina
    I am no server guy and we have issues with our speed so I come here asking for advise. We have a VPS with 2 cores and 2gb of RAM at a Magento specialized hosting company. Over the course of the last weeks our site speed has gotten worse, even though our store is new, has less than 1000 SKUs and not even 100 visitos a day. At magespeedtest.com we only get 1.87 trans/sec @ 2.11 secs each with a mere 5 concurrent users. Our magento log files are clean, we have no huge database tables or anything like that. When we take a look at our server real time stats, we see that the memory usage jumped up from about 34% to 71% and now 82% in just a few days in idle, with no visitors on the site. Our hosting company said that we do not need to worry about that as it`s maybe related to mysql which creates buffers (which are maybe not even actually being used) and what is important is CPU and swap - stats are ok here. They also said that the low benchmark scores are caused by bad extensions or template modifications on our side. We are not sure if we can trust that statement as we only have 4 plugins installed (all from aheadworks and amasty which are known to be one of the best magento extension developers). Our template modifications are purely html and css, no modifications to the php code. Our pagespeed is ranked with 93/100 in firebug and Magento is properly configured, so the problem really just gets obvious when there are a handful of users on the site at the same time. Can anyone confirm our hosting`s statement about memory usage and where can I start looking for a solution?

  • how to open many tabs in chromium but unload/disable inactive/notCurrent ones, releasing memory and cpu?

    - by Aquarius Power
    So I have 50 tabs opened on chromium, but that is using too much memory and some of the CPU. How can I have all those concurrent researches I am doing opened but not clog my machine? I think there should have a way that only the active tab is loaded in memory and running, and all the others should stay closed/unloaded from memory, until I want to look at them... Any extension can do something like that?

  • When is a program limited by the memory bandwidth?

    - by hanno
    I want to know if a program that I am using and which requires a lot of memory is limited by the memory bandwidth. When do you expect this to happen? Did it ever happen to you in a real life scenario? I found several articles discussing this issue, including http://www.cs.virginia.edu/~mccalpin/papers/bandwidth/node12.html http://www.cs.virginia.edu/~mccalpin/papers/bandwidth/node13.html http://ispass.org/ucas5/session2_3_ibm.pdf The first link is a bit old, but suggests that you need to perform less than about 1-40 floating point operations per floating point variable in order to see this effect (correct me if I'm wrong). How can I measure the memory bandwidth that a given program is using and how do I measure the (peak) bandwidth that my system can offer? I don't want to discuss any complicated cache issues here. I'm only interested in the communication between the CPU and the memory.

  • How to limit memory of a OS X program? ulimit -v neither -m are working

    - by hectorpal
    My programs run out of memory like half of the time I run them. Under Linux I can set a hard limit to the available memory using ulimit -v mem-in-kbytes. Actually, I use ulimit -S -v mem-in-kbytes, so I get a proper memory allocation problem in the program and I can abort. But... ulimit is not working in OSX 10.6. I've tried with -s and -m options, and they are not working. In 2008 there was some discussion about the same issue in MacRumors, but nobody proposed a good alternative. The should be a way a program can learn it's spending too much memory, or setting a limit through the OS.

  • GeForce 9600GT support for dual monitor setup

    - by Theo
    I have a NVIDIA GeForce 9600 GT (point of view, link) on an Asus M2V-MX motherboard. The card has one DVI, HDMI and S-Video output. The graphics card does not seem to support dual monitors: the driver control panel for the graphics card does not detect a second monitor that is attached via S-Video (which leads me to believe that it doesn't support dual monitors with DVI and the other connections). Would it be possible to use a VGA/DVI splitter to attach two monitors to the single DVI output on the graphics card? Would this allow for a dual monitor setup, or only mirroring? How do I know if the graphic card supports this? With this particular motherboard, would it be possible to use the onboard video for another monitor?

  • 8400GS causes BSOD in Acer M1610 running Windows 7 32-bit

    - by Arch Angel
    Title says it all, just installed the Nvidia card, I know this is a driver related issue I just don't know how to fix it I cannot find a driver version that will work not even the one that windows selects for the card, or the one on the disk supplied with the card. Any help will be appreciated. BSOD output: What happens when I try to install Any driver that does install causes a BSOD the driver disk says it supports windows 7 and the drivers on the disk cause a BSOD too i'm at a loss of what to do. EDIT: Yes I uninstalled the intergrated drivers. PCIE x16 Card from Gainward Tried multiple driver versions Versions that wont install because they cannot pick up card 190.38, 191.07, 196.21, 197.45 Versions that install and cause BSOD 258.96, 260.99, The drivers on the disc (not sure of the version) and drivers from the gainward website (driver version 263.14)

  • How to implement smart card authentication with a .NET Fat client?

    - by John Nevermore
    I know very little about smart card authentication in general so please point out or correct me if anything below doesn't make sense. Lets say i have: A Certificate Authority "X"-s smart card (non-exportable private key) Drivers for that smart card written in C A smart card reader CA-s authentication OCSP web service A requirement to implement user authentication in a .NET fat client application via a smart card, that was given out by the CA "X". I tried searching info on the web but no prevail. What would the steps be ? My first thought was: Set up a web service, that would allow saving of (for example) scores of a ping pong game for each user. Each time someone tries to submit a score via the client application, he can only do so by inserting the smart card into the reader. Then the public key is read from the smart card by native c calls through .NET and sent to my custom web service, which in return uses the CA-s authentication OCSP web service to prove the validity of the public key/public certificate (?). If the public key is okay and valid, encrypt a random sequence of bytes with the public key and send it to the client application. If the client application sends back the correctly decrypted random sequence of bytes along with the score of the ping pong game, then the score is saved in the database for the given user. My question is, is this the correct way to do it ? What else should i know about smart card authentication ?

  • Working on WPF application Memory Profiling

    Today, I am going to start with the task of memory profiling the WPF application, on which I am working from past few months. I have successfully done this in past, fixing a lot of memory leaks and improving the performance of WPF applications; As in past, I am hopeful of fixing some very interesting bugs and improve the application performance. I am very excited as current application is very different from the previous WPF applications I had profiled, all the previous application were pure WPF...(read more)

  • OpenSolaris / Nexenta problems with NetXen 4-port NIC card (ntxn driver)

    - by ewwhite
    Hello, I'm running NexentaStor Enterprise on an HP ProLiant DL180 G6 server. The onboard NIC interfaces surface as igb0 and igb1 and work well. However, I've added an HP NC375T 4-port network card using the NetXen 3031 chipset. This card should be handled by the ntxn driver in the SUNWntxn package, but that results in "ntxn0: failed to map doorbell" messages upon boot. The network interfaces don't show up. After some research, I found HP's driver package for the card. The release notes for the driver package state: This version of the Driver is supported only on Oracle Solaris 10 5/09 & 10/09. Oracle Solaris 10 5/09 & 10/09 contain an older version of NetXen P3 driver package called SUNWntxn. So, adding another version of NetXen P3 driver package using pkgadd command might result in conflicts with the NetXen driver binary & related files. Users are advised to uninstall native SUNWntxn driver package before installing the new package. The install completes, but I end up with a different set of errors in initializing the card. ifconfig ntxn0 plumb ifconfig: cannot open link "ntxn0": DLPI link does not exist dmesg output: Jan 29 07:20:17 ch-san2 ntxn: [ID 977263 kern.warning] WARNING: Memory not available Jan 29 07:20:17 ch-san2 ntxn: [ID 404858 kern.notice] NOTICE: ntxn0: Mac registration error Trying to manually create the device files: root@ch-san2:/volumes# add_drv -i "4040,100" ntxn ("ntxn") already in use as a driver or alias. Update the driver: root@ch-san2:/volumes# update_drv -f ntxn devfsadm: driver failed to attach: ntxn Warning: Driver (ntxn) successfully added to system but failed to attach Any ideas on how to get this driver working, or should I ditch the card and go with an Intel or something else?

  • Virtual Sound Card for Windows Server?

    - by Ian Boyd
    i have some software running on a server which requires a sound card to be installed. i'm trying to find a virtual, or emulated, sound card driver for Windows 2000 Server. It doesn't have to play anything, send streams anywhere, or do anything. It just has to be there. Note: This is a physical machine, but i want the solution that will port to a Microsoft Virtual Server machine running Windows 2000 Server. (in other words, buying a sound card will not work) i've already tried the REaudio driver from MixW; it does not work (no sound card virtually appears in the system). Update: 1k views? Obviously people are finding it an interesting question to keep stumbling across it. Up-vote it!

  • Can I monitor a service's memory/cpu usage on OpenSolaris?

    - by Phillip Oldham
    What would be the best way to monitor a service's memory/load on the OpenSolaris platform so that one can send alerts and automate service management (restarts, etc) based on "rules"? On the linux platform I use Monit, but since OpenSolaris has SMF I thought there may be a complimentary service "built-in" if SMF doesn't have those features and I'd prefer to use a standard OpenSolaris app if there is one.

  • Recovering Pictures & Movies from Formatted Memory Card

    - by Donotalo
    I thought I've copied all of the pictures and videos that I've taken using my digital camera Canon Digital IXUS 860 IS to my computer. Then I format the memory card. Then I found I didn't take all of the files! I don't have any other means of connecting the memory card to computer except via the camera. But the camera doesn't show it as a removable device directly in my computer so programs like Glary Utilities and PC Inspector didn't find the drive. I didn't take any picture after I formatted it. Is there any free software that can help me to get the pictures and videos? My memory card is an 4 GB SDHC card. Thanks.

  • I Can Edit SD Card on Windows XP but Not on Windows 7

    - by David C
    I have an 8GB SDHC card which I have used to upload pictures onto my Windows XP machine using an SD card reader ("SanDisk Ultra II"). I could also delete pictures and create folders on the card. I recently obtained a new computer that runs Windows 7 and, while I can view and upload the photos, I am unable to delete photos or create folders. When I attempt to do either of these two operations, the desired option does not appear in the menu ("Delete"/"New Folder"). Also, the shortcut keys do not work (e.g. the Delete key and Alt+F+W+F). I have attempted to change the Properties from Read-only, but am greeted with a "media is write protected". I should add that when I insert the Card Reader back into my Windows XP computer, I am granted full write permissions. Why can't I modify the SD Card from Windows 7? And, related, how can I fix this issue? Let me know if you have any additional questions. Thanks!

  • Atheros AR9485 wireless card doesn't work in an ASUS K53E

    - by John
    I just installed Ubuntu 11.10 32-bit version in dual boot mode on an ASUS K53. Every thing seems to work fine except for the wireless. The wireless works on Windows 7. Ubuntu finds the wireless card, but it does not appear to be turned on. The only physical means of turning on the card is the FN-F2 key combo. That works on Windows, but not in Ubuntu.
