Letter of Volatility

Please provide me with a Letter of Volatility for the Motion Control Boards PCI-7344 and PCI-7354. I would also appreciate one for the Video Capture Board PCI-1409. A declassification procedure for each of these boards would also meet my requirements. Thanks.

I don't believe there is a price for the letter, but I could be wrong. The best way to proceed with this, if you call us at 1-866-ASK-MYNI (1-866-275-6964) and create a service request, or I can pull your information and send you this information myself if you give me permission to access your information for that purpose.

  • Letter of Volatility for PXI-8108?

    Is there a Letter of Volatility Available for the PXI-8108 describing volatile and non-volatile memory

    To anyone interested in getting a Letter of Volatility (LOV):
    We have started posting LOVs on some product pages of our website in the resources section, so it is worth checking there before contacting us. In many cases, as it was in this one, we have not made the LOV publicly accessible at this time.
    In that case, the most efficient way to get LOVs is to contact our support engineers by calling 866-ASK-MYNI (275-6964). They will be able to talk to you about your need for the document and speak with our internal resources to get that to you fairly quickly.

  • VXI-1000 Letter of Volatility

    I'm trying to locate a Letter of Volatility for the VXI-1000 Mainframe, but haven't had any luck searching the web site.  I tried to submit a support request but don't have a membership number to do so.  Any help would be greatly appreciated.  Thanks. 

    Hello mdbeer,
    The VXI-1000 main frame was End of Life (EOL) in approximately 1997 and thus the documentation such as the Letter of Volatility is unavailable. I apologize for the inconvenience.

  • Volatility letter for VXIpc-872B?

    To satisfy our security requirements, I need a volatility letter covering the VXIpc-872B controller (or, more generally, the VXIpc-870 series of controllers), but I couldn't find one on the NI web site. Can someone send me one?
    Also: By reviewing the user manual I've already identified at least two types of nonvolatile memory in the controller -- battery-backed CMOS for BIOS settings (and more?), and an EEPROM, half of which is user-accessible. The manual provides a procedure for erasing the battery-backed CMOS, but I didn't see one for the EEPROM; does such a procedure exist, at least for the user-accessible half?

  • PXI-2599 Declassifi​cation/San​itization

    I am going to be using a PXI-2599 switch card in a system with data sanitization requirements.  I have a letter of volatility listing memory and sanitization requirements, and it says that a low-level utility is required to sanitize PROM on the board.  Where would I be able to find this utility, or specifications on how to write one?

    Hello,
    This utility is currently under development by R&D.
    However, something to note is that this utility has never been provided to a customer. The only way to write to the memory of the card is through a low level program owned by NI R&D and this program has not been shared. The only things that are stored on the memory of this card are the serial number, the module identity, and relay count information. An attempt to write application specific information to this memory component without knowing what you are doing would most likely corrupt the board and would not be wise to do. Let me know if you feel that you still need this utility.

  • Volatile Keyword

    I am confused with the keyword "volatile". Few questions.
    I have seen two different descriptions for this keyword.
    1) Processors store data in their own registers for more efficient use.In Multiprocessor environments, the "volatile" keyword will ensure that a piece of shared data is always picked up from the (common) memory location and not reused from the (private copy) register for that processor.
    If this is the case, then dont we require to use this keyword for all class level variables(static) ? Or does putting static keyword ensure this? (A static member is supposed to hold a common copy for all instances - how does it internally work in a multiprocessor environment?)
    Is it possible that an instance may be partly serviced by one processor and partly by another in a multiprocessor env? In that case, dont we need to declare all instance variables as "volaile"?
    2) "Volatile" keyword ensures that the data is "sequencially consistent" - meaning
    if we have --
    volatile int a = 5;
    volatile boolean flag = true;
    Then if flag is set to true, then a will already have been set to 5 always (this means this may not always be the case in the Runtime env, if the keyword is not volatile -- so in multithreading env..there can be problems if global variables are not "volatile"
    Am I on the right track? The two descriptions of "volatile" seem very different. Are they both correct? I also read that many JVMS dont implement this as of now..so where do we stand in the use\relevance of this keyword?
    Thanks,
    Mathew Samuel.

    If this is the case, then dont we require to use this
    keyword for all class level variables(static) ? Or
    does putting static keyword ensure this? (A static
    member is supposed to hold a common copy for all
    instances - how does it internally work in a
    multiprocessor environment?)First, lets correct one of your statements. You say, "A static member is supposed to hold a common copy for all instances" It may seem subtle, but a static variable is associated with the class, not any instance. There doesn't need to be any instances of a class for a static to exist. The point is that there is not a 'copy' for each instance.
    In a multi-threaded environment, each thread can cache it's own data. This is for performance. It takes time to keep the threads from interfering with each other.
    Is it possible that an instance may be partly serviced
    by one processor and partly by another in a
    multiprocessor env? In that case, dont we need to
    declare all instance variables as "volaile"?If you synchronize access to variables, you don't need to declare things as volatile. volatile isn't used all that often. Mainly, it's for certain situations where full synchrionization is not required.
    2) "Volatile" keyword ensures that the data is
    "sequencially consistent" - meaning
    if we have --
    volatile int a = 5;
    volatile boolean flag = true;I can't really confirm or deny this.

  • Fixing Double-Checked Locking using Volatile

    Oooh - what a scandalous subject title! :)
    Anyhow, I was expanding my knowledge on why the double-checked locking idiom used in Singleton classes fails (after reading that JSR-133 is not going to fix the problem!), when I read http://www.cs.umd.edu/~pugh/java/memoryModel/DoubleCheckedLocking.html and found a spicy section titled "Fixing Double-Checked Locking using Volatile" (at the very bottom of the document).
    As it is quite hard to find information (all sources revisit all the basic problems), I was wondering if anybody could back this up/refute it.
    Just one more thing. I anticipate that many people who are researching this matter would like to have this clarified, so it would be beneficial to keep posts very much on topic. There is already a lot of information available about double locking failures in general.
    The problem this post faces lies in a lot of statements saying "using volatile will NOT fix double-checked locking" that refer (I think) to the current JDK.
    Thanks heaps!

    Volatile only checks that not more than one thread is accessing the variable at the same time (amongst other things of course), so in the example, it could cause problems. Let me explain a little here. Given a situation where two threads wish to aquire the Helper:
    Step 1: Thread 1 enters the method and checks the helper status
    and sees that it is null.
    private volatile Helper helper = null;
    public Helper getHelper() {
      if (helper == null) { // <!-- Thread 1 requires helper, and sees that it is null
         synchronized(this) {
            if (helper == null)
               helper = new Helper();
       return helper;
    }Step 2: Thread 2 enters the method, before the lock can be
    acquired on the this-object and notices that the helper is
    null.
    private volatile Helper helper = null;
    public Helper getHelper() {
      if (helper == null) { // <!-- Thread 2 requires helper also
         synchronized(this) { // and it is still null
            if (helper == null)
               helper = new Helper();
       return helper;
    }Step 3: The first Thread creates a new Helper
    private volatile Helper helper = null;
    public Helper getHelper() {
      if (helper == null) { // <!-- Thread 2 waiting for lock realeas
         synchronized(this) {
            if (helper == null)
               helper = new Helper(); // <!-- Thread 1 creating new Helper
       return helper; //
    }Now for Step 4, there are a few possibilites here. Either Thread 1 returns the helper it created, or Thread 2 can create the new Helper before the Thread 1 returns the Helper. Either way, the result is unwanted.
    private volatile Helper helper = null;
    public Helper getHelper() {
      if (helper == null) {
         synchronized(this) {
            if (helper == null)
               helper = new Helper(); // <!-- Thread 2 creating new Helper
       return helper; // <!-- Thread 1 returning Helper
    }The code can also create interesting situations (deadlocks?) due to the synchronized(this) statement used in a ... creative way in this case.
    I might be wrong of course. Just my �0.02.

  • When is volatile needed?

    I know you need to use the volatile keyword when multiple threads might be accessing a primitive or reference without external synchronization. Suppose your class implements Runnable and has one member variable, a final int. The constructor takes an int and simply assigns it to the one member variable. You dump it into an ExecutorService with submit()--do you need to use volatile to make sure that the other threads see the assigned value of the int? The int is only assigned once in the constructor.
    It would seem to me the logical answer here is no; the VM would enforce a memory barrier between unassigned variables turning into assigned variables, but I'm just making sure, since what I've found doesn't really clarify this for me.

    Just out of curiosity, suppose the field was
    non-final. Would volatile still not be needed?If the value never changes, and if you don't let a reference leak out of the constructor, then I'm not sure if you'd need volatile.
    In general, it's possible for one thread to set a value, and another thread to never see it, if there's no syncing and no volatile. I thought that something in the new JMM prevented that in this particular case--i.e., a constructor, but I'm not sure if that's true, or what the details are.
    The answer should be here: http://java.sun.com/docs/books/jls/third_edition/html/memory.html#17.4

    You can seach the net for solutions like this one http://appletvvpn.com/how-to-connect-apple-tv-2-to-vpn/ another idea is to use a PC as the control and fit that with a wireless card and set up a ad hoc wireless network that the Apple TV uses.
