overflow memory for the producer consumer

• Data types in the design for the producer consumer model

  Is it possible for me to use any type of data in a model of design producer consumer, without specifying specific data type?

  what I mean is if there is a way to connect to a data type with which I can use any other type of data, not to mention that one that I have connected, and if not, how can I specify the data type for a number or any other data type, for use in a design of producer-consumer model?

  You can make a part of your cluster of data a Variant.  It will take any type of data.  A common architecture for the producer/consumer is a cluster which is an enum and a Variant.  The enum contains all possible "orders", you might want to send.  The variant contains data that could be of any type.

  Ungroup you in the consumer and get the enum and Variant.  Attach the enum to a case structure.  In the specific case, convert the variant type in a data type of regular LabVIEW and with it as you please.

• Using the producer/consumer with GPIB/VISA model

  Hi all

  So I have a .VI I learned to communicate with my camera, I joined. I tried strip down as much as possible, just to understand the concept. It basically just takes a resource VISA name, use this open VISA, then uses the same resource VISA to write a command that reads the data from my machine (xall?) and then bed in 500 bytes and which prints. If it works, and it's good.

  I try to use producer/consumer model for doing essentially exactly what this guy. I have a RLC, I want to press a button that starts my measure, I want him to taste several times per second, save the data in a text file or .csv and then stop when I press the stop button. Thus, he will be given indefinitely potentially.

  I would like to have the data in a format something like:

  Time C R

  0 5.0 4.3

  ... etc.

  I read the link of model p/c above, but my LabView knowledge is still low. Currently, my plan is to take the part of read/write of my attached VI, which are a sub - VI and then put that in the pink box in the VI for the producer/consumer above page that is labeled "produce data to be placed in the queue":

  

  What prevents me to do this, it's that I can't get the piece of read/write to work properly as a standalone Subvi.

  What is the right way to go about this?

  Thank you!

  I put if you actually found data of your instrument.  Your instrument is not made to take new measures or just send you the last reading, she did.

  Insofar as the file IO, I recommend that you learn to use the palette for the file IO functions.  You need to create your file before your loop, write in a text file inside and then close after the loop.  I don't do the thing the comment on the express VI entry will do what you want.

• First try the producer consumer Architecture: continuous play and dynamically update settings.

  Hello

  I am currently working with two instruments; an Agilent E3646A and a NI 6212 BNC. My goal is to have the 6212 continuously take measures according to predefined parameters while the E3646A parameters can be continuously updated. This combination simple instrument aims to help me learn the manual architecture; continuous measurement, output dynamic controls and instruments more will be added in the future.

  I've already posted on a similar, but more complicated configuration (http://forums.ni.com/t5/Instrument-Control-GPIB-Serial/Split-second-lag-when-controlling-two-instrum... and was advised to try the producer consumer Architecture.) I found the documentation on the website (http://www.ni.com/white-paper/3023/en/, https://decibel.ni.com/content/docs/DOC-2431), searched the forums and built my own VI. While my first attempt at a producer consumer Architecture has solved some of the problems I had when I posted on the subject, however, new questions have been raised regarding the reading and adoption of the VI.

  I am currently able to run the VI and update the settings on the device. Previously, I'd get a freeze while the instrument has been updated and could not switch settings until it was done. This has been resolved, although that reading updates only when a parameter has been updated, although it is outside the structure of the event. In addition, the Stop button does not in any context. I also got occasional mistakes on the part of Deqeue, but the major part of the sentence is error-200279 'A tried to read samples that are no longer available' to DAQmx Read. I realize that there is a problem in my loop of producer but have not been able to find a way to solve it.

  This is my first attempt at a producer consumer Architecture and already I can see that it is a powerful tool. I read as much as I could and looked at examples, but should have some problems at the beginning. Would be very grateful of any advice so I can take full advantage of the architecture.

  Hope to hear from you,

  You're going to overflow this buffer, unless the events are generated faster than "sample rate/number of samples.   Period.  Nothing could be simpler.

  You don't need a local to stop your curls.

  Try something like this attachment.  I simply moved the structure of the event in its own loop dedicated since it had nothing to do with acquiring data at all.

  Data acquisition loop stops very well when you destroy the task and destrying the stops of power queue (sending the default values of the queue for the power control) for EXAMPLE, to ADD a group of setting 'Safe shutdown' to a 'package' and it wire to the Center terminal (Prototype).

• Convert single while loop with variable Timing literal to the producer consumer

  I have a controller for a biological system that updates every n minutes or every minute 2n, under certain conditions. My app has a synchronization controller calculates if the current iteration is n or 2n and feeds the output of this calculation in a loop of "Timing" VI in my all. If I understand correctly, this is similar to the issuance of an order of sleep() in a language similar to C and should be avoided. I'm refactoring my code and I heard that they are well suited for this kind of things. Here's how it should work:

  1. Loop begins at the time T, T is saved.
  2. Schedule controller runs and calculates if loop will get minutes 2n or n minutes. This controller will take a number of milliseconds to complete, so we are is more to time T.
  3. Now that the update interval (n or 2n, let's call it u) is known, the loop must until T +u fill.
  4. The PDC is executed, but a number of milliseconds to execute.
  5. The rest of the time until the next iteration of loop should produce the CPU for other processes.

  It sounds to me like it's the kind of a real-time system, although as long as we are in the minute of the original deadline, there will be nothing wrong.

  What the producer-consumer loop would look like? Assumed that the synchronization and the main order controller are separate from the VI.

  
  

• recommendation of the memory for the guest operating system

  Hi guys,.

  What happens if I don't set up the limits and booking hotel and leave all default? What is the point of the week in this configuration? If I leave all default each VM does not use memory a cpu as it needs?

  Thank you specify in advance

  To add the tips of memory... Many people allocates memory for the virtual machines that will never be used, and ultimately you consume the memory of your host much faster than necessary. Start low when allocating memory to a virtual computer. Adding memory is simple to make, after you have collected on the functioning of your host performance data. The Performance tab will show you what is happening.

• Cannot terminate everything in a loop to the producer/consumer

  I have attached a simple vi which was built from the producer/consumer (events) model.  In vi I set up a counter.  I want to be able to complete the meter when you press the stop button.  This does not work as expected.  The meter goes to its full count before the program stops.  The vi works as expected when run in execution to highlight mode.  Cannot understand it.

  Thanks in advance.

  Race condition.  No matter what time something behaves differently with that highlight run it at full speed, and suspect it is a problem of synchronization due to a race condition.

  As soon as your producer loop has the command queued up, she is ready to handle the next event.  If you press the stop button, it is ready to deal quickly and the stem while the ends of the loop and Stop immediately gets back to false.  This probably happens before the loop of consumer has the opportunity to read the local variable of the button stop in the moment, it's true.  Have your consumer while loop redefine the Stop button to false instead ensuring consumer loop has a chance to see if it is true.

• Instead of using the structure of the event with the producer consumer?

  I used the architecture of producer-consumer in the past to control a state machine with the structures of the event.  I'm working now with the basic version of LV that does not include the structure of the event.  Can anyone recommend alternatives to the use of the same architecture in this case?  Thank you, David

  Before the introduction of the structure of the event, the only option was the election.  Control terminals are in a time loop (the producer) with shift registers and a wait, usually about 100ms.  At each iteration of the loop, the control's current value is compared to the previous value.  If it has changed, and then take appropriate action.  Andrey suggested, queues are a good way to pass information between the loops.

  It works for the equivalent of the value change events.  Things like mouse to top or filter events were much more difficult or not possible.

• Fingerprint memory for the LabVIEW 7.1 development system

  Hello

  I would like to know the size memory for LabVIEW 7.1 full development System.Both during the installtion and to develop applications later.

  If anyone can help. Thank you.

  There is no one answer for this, as this varies considerably.

  For what is on the disk, if my memory serves, the 7.x base takes a few hundred MB, but which could greatly inflate according to the modules and drivers you add.

  For the RAM, I believe than 7.0 used to identify approximately 20-50 MB immediately after loading, but this number then would also change a lot over time depending on what you are doing. Loading, editing and execution of code just regularly change the amount of RAM used.

  Why do you ask? Also, are you aware that 7.1 is relatively old now (came out 7 years ago)?

• State machine in queue with the producer consumer

  Hello

  I am trying to build a VI where the user allows some Boolean controls on the front panel.
  VI uses a producer consumer in which based on Boolean values clicked architecture.
  some States are queued one recorded in a table.
  After the user is done by selecting, Boolean values should get disabled and the table of States
  should be indexed one after the other.
  It is an attempt to solve the review model car wash.
  However, the VI does not generate the required results.
  Can someone help me please understand what is the correct way to this implementation.

  Thank you

  Its because you have wired the consumer while loop the first stop. Remove and in your loop of consumer, make a comparison of the States that you receive and if it is equal to stop, stop the loop of the consumer.

• HP recovery D needsrepairs says not enough memory for the backup

  need to know which files can be deleted or how re-branded more memory for this partition without damaging it.

  Do not delete anything and do not write something here! And do
  do not try to assign any disk space more (it is not called 'memory' on a
  hard drive) to it.

  It is a recovery partition; its purpose is to provide what you need
  to reinstall Windows if it should be necessary. Anything for her and
  you will lose this ability.

  Your computer comes with instructions on how to write its contents
  on a DVD so that you would be able to reinstall Windows if your drive is dead.
  Which should have been the first thing you did when you got the
  computer, then do so immediately as soon as possible.

  And another point: backup to a second partition is by far the
  form of backup is the lowest. It's better than no backup at all,
  but barely. I do not recommend backup a second not removable
  hard drive (or worse, a second partition on your hard drive only)
  because it leaves you likely to be simultaneously the original losses
  and backup for many of the most common hazards: severe defects of power,.
  nearby lightning, virus, attacks even the theft of the laptop.

  In my view, secure backup must be on a unguarded and removable media
  in the computer. For backup really secure (required, for example, if the)
  the life of your company depends on your data), you should have several
  generations of backup and at least one of these generations must be
  stored off-site.

  My computer is not used for business, but my personal backup plan
  use two identical removable hard disks, I alternate between the two,
  and use Acronis True Image to create a complete copy of the primary
  drive.

  I also use a 1 GB USB key pair to make more frequent backups
  my most sensitive data (for example, financial information). For this, I just
  Drag and drop.

• Reservation of memory for the server sqql

  Hello

  I am running two SQL servers with 4 virtual CPUs and each has 12G of RAM available.

  We have noticed that sql process uses only 180MB of RAM while SQL is designed to use all available memory... We decided to use a reservation of memory for these boxes and grant a full 12 GB for each booking.

  (1) that would be really useful?

  (2) I noticed that after having reserved memory, that the system has taken something like 10 minutes to start, can anyone explain to me why?

  Thank you

  The shares of resources can be adjusted if necessary. I don't think that you need. As well as the host has only a single virtual machine now, who knows what the future may bring. You add multiple virtual machines and you will start to do the math. ESX let his work resources and balance. If you see performance degradation then start looking at the distribution of resources.

  As for the CPU that the virtual machine is not the only object on the system might compete for processor resources, you also have the SC. When you give the VM 4 vCPU find the system to wait on the availability of all hearts.

  You can reduce the number to 2 and even play with the processor affinity if you want, you should try to determine the weather your SQL system really needs the CPU/MEM tweaks (in my experience IO is the cause of the headache of performance most SQL).

• Satellite 1130 - more memory for the chart

  Hello

  is it possible to change the memory of the integrated graphics chip of a satellite? right now I'm just 64 MB. When I bought it, 2 years ago they said it can be extended, but so far it is not possible to change it in the bios (phoenix)...
  Any suggestions?

  Hello ric

  Sorry, but something like that is not possible. The only thing that you can develop is RAM.

  It is very interesting to know who they are. You're probably talking about the local dealer. I also heard that they often give some useful tips, information and suggestions.
