First race in call loops

• Other results: preliminary report does not properly during the first run in a loop

  I have an unusual problem with NI TestStand 4.1. I have a loop For and it contains, I have a call from sequence configured as a test of numerical limit. This test is configured to report additional results. All other results are preconditioned test cases. Here's the unusual part: during the first iteration of the loop, the test passes yet additional results for the parameters of all inputs are reported (output parameters are not presented at the time, but more on this later). Spend all additional this test iterations in the loop For and additional results are not reported.

  Regarding output parameters... If a test fails I'm expecting (input and output parameters) results to report. However when I encounter a failure only the additional results that are output parameters are displayed on the test report. Input parameters are not reported.

  If anyone else has experienced this? My expectation was that all additional results would be declared in case of failure. In addition, in the absence of a failure I expect not to see additional results. Thanks in advance!

  The short answer is that the condition of additional results for input is evaluated before it's called the subsequence, so that it uses the value of the previous iteration Step.Result.Numeric (or by default on the first).

  You can see this described as stage 15 in the following link:

• LabVIEW 8.6.1 AMD Multi Core Crash with call loops

  Hi all

  I tried, but I couldn't find all the messages with my exact situation.  Here it goes:

  I have a multi-core AMD Phenom 64 processor and I'm running Windows 7 64 and I am running an application in LabVIEW 8.6.1 in compatibility mode.  (I know, not a good idea)  I have a pretty complex application with several timed loops and the different ways to talk to FieldPoint (FieldPoint 6.0.6 and experimentation with Modbus talk to cFP-180 x).  You may be wondering why I'm using call loops.  It is an application of RT which can also run on Windows using structures conditional disable, etc.

  I had met sporadic crashing earlier in my files executable for more than a year and used a lvalarms.dll in only patched version my executables.  It was on a totally different processor and we were running Vista at that time.  Now, I notice a very similar behavior on 8.6.1, except now the development environment all crashes or breaks down my executable compiled as well.

  I found this KB, but he was referring to problems observed on LabVIEW 8.5, and the utility of the OS is only for Windows XP.  As recommended in the KB, I used BCDEdit to set the flag onecpu and now everything seems to work normally.  My PC is now significantly slower, however, and I wonder if there is another workaround solution that I might be able to try.

  If you have read so far and who have followed my description you already have my gratitude.  If anyone else has experienced this?  Someone at - it ideas?

  Thank you very much

  Jim

  Alright.  In case someone else runs into this apparently dark scenario, here's workaround solutions I've found:

  1. see if the problem goes away by setting the processor affinity using the Task Manager. Open the Task Manager, look under the "Processes" tab and right-click on the process. (for example LabVIEW.exe or your executable)  Under the context menu which select "set affinity...". "and select only the CPU 0.  In my case, I have a quad-core processor, so I up to four logical processors that are displayed in the dialog box that results.

  Run your application code or the executable file for a while, and if everything seems to be stable, it would seem that you have isolated the problem successfully.

  2. one of the solutions is to disable additional logical processors for the entire operating system, although there may be negative implications on performance.  In this case, try the steps in the lower part of this KB.  I have Windows 7, so I used the utility of command-line bcdedit with no problems.

  3. Finally, a really interesting option that is well worked for me should automatically set the affinity of the processor for each individual process.  There is at least a utility available to achieve this.  I've now changed my LabVIEW 8.6 shortcut to call RunFirst, which sets the processor affinity for LabVIEW to automatically use the first logical processor.  This way I can still use my processor image for all it's worth except in applications that have problems with it.

  I hope this helps someone else out there one day.

• happy 40th for the first cell phone call

  Today - 40 years - the first cell phone call was made by Martin Cooper of Motorola using what yould become the Motorola DynaTAC 8000 x.

  Weight - 2.5 lbs

  Cost - about $4000.

  http://www.FOXNews.com/tech/2013/04/03/first-mobile-phone-call-was-placed-40-years-ago-today/?intcmp...

  Heres another 40.

  Can you imagine saying one of those people holding the phone/anchor in 40 years, he would be carrying a device that weighed a couple of ounces and had more computing power than the first lunar module? I have now, imagine what will bring the next 40 years.

• First iteration of a loop problem

  I'm having a problem with the first iteration of a while loop. I want to save all the data a data acquisition over a period of time. In order to keep the unique 'small' file, I'm doing a VI that produce a new file every 10 min. about. But the first file I want to do is not due to the following problem:

  The first time I use the DaqMX read in the loop, it returns a blank. Why does do that?

  I'm not entirely sure why, but I just set the number of samples to a specific value so that you do not need the function of Ms. wait 100 in the loop.

• A problem with delays in call loops and DAQ

  I'm programming a simulation for nuclear Rewetting for a reception centre to my company in Switzerland. It is a "fuel rods" heating and then fill the water Chamber. The pump starts automatically as soon as the core of the stem reached 750 C. After that, a requirement that the flow rate be checked to ensure the operation of the pump in the necessary conditions. If not, the heating must be stopped to avoid, well... meltdown. However, we must allow 10 seconds for the pump to respond, while allowing a rate of acquisition of data from 10 to 100 Hz.

  The challenge is that I can not add a delay in my other main loop delay all acquisitions, but I can't understand how to trigger a device loop (with data acquisition for the single channel flow control) and the main loop when the loop device determines if the flow a initalised, answering the main loop with the agreement.

  I think that a large part of my confusion is in the interaction between loops and knots of default comments labview's willy nilly. The only solution would be to have two 'core' loops that do not communicate with them, but rather to do the same thing while operating different synchronization? Tell me if you want I will post the file (even if its on a unnetworked computer and I don't think that it would also be useful).

  Hi Peter,.

  I'm sorry for the inconvenience this causes. We know the performance issues that were introduced in version 7.2 with some AMD GPU cards.

  We're now investigating the problem.

  I know that's not ideal, but in the meantime, here are a few workarounds:

  -Back to 7.1

  -Disable GPU acceleration when you use these effects

  Here is a list of the effects that seem more problematic:

  * Fast color corrector

  * RGB curves

  * ProcAmp

  * Feather edge

  * Effects Lumetri looks

  These effects do not appear to hinder the execution in my tests:

  * All blur effects

  * Three way color

  * Harvest

  * Caches

  * Levels

  Again, I apologize the problem caused.

  Best,

  If you do not have a stop() command in frame 50, try putting an it, or explain why you will not.  Certainly put a trace in the frame of 50 to see if you keep coming back, as in... trace ("under 50");

• Why the table in the output of MT complex waveform modulation FSK 255 elements missing?

  Hello! I posted my question in the LabVIEW forum but an application engineer suggested I post here. I'm new so any help would be appreciated

  I use this example FSK in LabVIEW (VI is attached). As it can be seen in the block diagram, the number of samples by specified symbol is 512. If I run 2 - FSK, I have 1 bit per symbol. So I if I have 128 bits, 128 symbols. and if I have 512 samples per symbol, I expect 65536 samples/elements in the complex waveform of the MT output modulation FSK. However, I get only 65281 elements in the table. There are 255 missing items.

  If I run 4 - FSK and have 128 bit or 64 symbols, I expect to 32768 in the table. But then again, I'm running out of 255 items and get 32513.

  Am I missing out on something? Have I misunderstood something? Thank you very much for your help.

  I get the same results as you!

  I Dove a little inside, and it seems that the code that generates the symbols, two layers down, which reports an explanation to this.

  If you open MT modulate FSK.vi, then mod_FSK modular Phases.vi discontinuous to generate in the discontinuous case of the structure of the case, you will see the following code.

  

  You can see that when Reset is set to True (the default) and the external-loop for is in his first race, the inner-loop for work (samples per symbol) / 2 + 1 times (in your case, this number is 512 / 2 + 1 = 257.) Subsequently, the inner-loop for runs with 512 for each outer loop for iteration. This means that the first round fail to 512-257 = 255 samples, which causes the total to 255 less samples.

  I don't know what is the motivation behind this design. As a test, you could connect in a constant False to Reset of the MT Terminal modulated FSK VI, which causes all the samples to generate.

  Hope that clarifies it.

• LabVIEW FPGA while loop (first call? (VI) question

  Hi gentlemen!

  I am creating a LabVIEW FPGA VI appearing in a WHILE loop. He has a first call? VI in which, in the first occurrence of the loop, a variable must be initialized to some value. However, when I incorporate the VI in the FPGA, it would seem that the first call? VI has not been called. I also tried this implementation through registers at offset where the registry is initialized outside of the WHILE loop. However, the result is always the same. May I ask how the LabVIEW FPGA functions when it comes to everything IN a loop? Thank you very much!

  For some reason that I don't me remember not I avoided the use of FPGA FirstCall and instead, I use a change sign boolean, son of genuine in the terminal, on the left and a fake in the while loop to the right Terminal. As a result, you get a true for the first iteration only, in exactly in the same way that the function of FirstCall. It could even use fewer resources on the FPGA?

• Sound is played at the first time when it is called by VI

  Hi, I am creating a VI that creates bursts of noise of specific terms in the sequences. My problem is that the sound generation VI only plays the sound the first time it is called. I tried to put VI in a for loop to see if I can get to play several times, but no matter what I do it plays only generated sound once.

  I found the problem. Thank you. The problem was with the timer not reset in the loop (it fixed with a shift register) on second or other calls. Thus, the loop was ignored that the timer has been greater than the value specified after the first time through the loop.

• Simulation of phone call throws the null pointer exception in the first round

  I am trying to simulate a telephone call, but he throws null pointer exception in the first race after that the Simulator is launched. It works very well in subsequent executions. This is the scenario in single line and multi mode. I was able to test this on a camera right now.

  Can anyone guide me as to why this exception occurs? And how to solve?

  The code I used is:

  Single line

  PhoneArguments

  Call = new PhoneArguments(PhoneArguments.ARG_CALL, )

   

  Phone_Number);

   

  Invoke.invokeApplication (Invoke.

   

  APP_TYPE_PHONE

  Call);

   

   

   

  MultiLine:

   

   

  Phone.initiateCall (Phone.getLineIds () [0], Phone_Number)

   

   

   

  Thank you

   

   

  This null pointer exception will not come to the real device...

  According to my knowledge, you call another application so that the user must press the back button to return to your application.

• Geocoding takes VERY long for the first call in each session

  Hello
  
  We are moving to a system of very short response time where the user sends a query via mobile phone to our based Oracle server and the response THAT SMS must return a list of points of interest at a certain distance from the mobile phone.
  
  Previously we were using Oracle 9i, now we went to 10g (EE 10.2.0.4.0). Given that 10g supports geocoding out of the box, we intend to use it. What we are experiencing, this is when we create a new session, and then the first geocoding/reverse_geocode call takes about 1 minute in our test environment (that means 100% CPU load on the side of Oracle Server), the following calls are in the [http://0.1.. 0.6] second intervals. We only use sdo_gcdr.reverse_geocode () and sdo_gcdr.geocode () procedures.
  
  In a space book, we found:
  + "Note: the first call to a function of geolocation in a session requires several time (is longer) than subsequent calls." +
  "+ Is because the function must load and analyze arrays of profile". +
  
  Profile of tables do not change, why is he not analyzed at the start of the RDBMS and only once, not for each session?
  
  Is there a solution?
  
  Kind regards

  The patch that I suggest is precisely to allow the geocoder to work effectively in many countries. Its effect is to only load the profile for the country being geocoded. If profiles are loaded progressively as needed, avoiding the High overload at the beginning. With this patch, the first geocode a meeting is second.

  The time you specify (a minute for the first geocoded in a session) clearly indicate a problem. If this problem is not with bad indexes on the table of the region, you can check the box caching (CACHED_ADMIN_AREA_LEVEL in GC_COUNTRY_PROFILE should be 0).

  I think yiou need to capture a complete SQL trace of this first geocoded, so we can diagnose accurately what is happening.
