Does running multiple tasks on the multifunction DAQ card cuase any problems ?

[Satya the truth]

Dear all,

I woul like to use the 6024E card for running atleast 3 tasks simultaneously, does it cause any problem ?

Any software issues?

I have a 3.0 GhHz HT processor with 256 MB Ram.

Any issues with labview ?

Satya,

It depends on what the tasks are doing. If they are completely seperate, then you should be fine. But if any two tasks use the same resource (e.g. Analog input 0 in one task, and Analog input 0 and 1 in another) then you will get a error, something like "Resource unavailable". But if your 3 task are completely different, e.g. on is an analog input, another is an analog out, and lastly one is digital out, then you will be just fine. Hope that clears things up for you.

Dear GDE,

Thanks for your reply. I probably will be running independent tasks, therefore it shoudn't be a problem, however I have doubts about the software, like sometimes labview used to hang even when I ran a single task. I have a 3.0 GHz machine with 256 MB ram, is increasing the ram a solution ?

Satya,

Increasing RAM will always help. Especially since you are running with only 256 MB RAM, for any type of work now days I would recommend 512 MB, if not 1GB. Now if you are getting LabVIEW to crash with a minimal application going this may indicate other problems. If you have a memory leak in your program, that could cause a crash and with 256 MB of RAM you will see a crash sooner, but it can still happen even with 512MB or 1GB. So double check for any memory leaks. Minimize the number of programs running in the back ground. If LabVIEW crashes with any kind of error, that would give us a good indication what is going on.
