programmatically creating parallel loops

[Ujjval Shah]

Hi

I have a VI which i want to call a number of times defined by the user. so i can simply put the vi in a for loop and call it accordingly.

now each time the vi is called, it executes data independently of the previous call. Hence i want to run them in parallel using reenterant subvi property.

However the no of times a vi needs to be called can be determined only during run time..

How do i do this?.. hope i have made my question clear

thanks in advance

What does the subVI do? Is it supposed to run continuously? Does it have a loop? If so, then you should launch the VI using the VI Server functions. This allows you to launch the VI and then go to the next iteration of the loop to launch a new instance.

Check the examples that ship with LabVIEW on using the VI Server to launch VIs dynamically. You will also find numerous examples in this forum.

Hi smercurio_fc,

Thanks for your reply.

I tried using VI server reference.

The subVI has a for loop inside it

However i am not getting the desired result. According to what you said, using the vi server reference in a loop should launch the subVI  and move on to the next iteration and then call another clone of the subVI- correct me if i misunderstood-.

and if i understood correctly then this is not happening cause LabVIEW is waiting for this called subVI to execute completely and then only it moves on to the next iteration. I want multiple instances of the same VI to run in parallel

initially i thought it might be a problem of the subVI being non-reeenterant, but even after making it reenterant, i am having the same problem.

pls share your thoughts and help me.

Thanks

ok, i just figured it out.

the example of multiple pop ups came into handy.

Thanks!

problem solved
