Labiview dll parallel code

[buddace]

Labview 2012 in PXI (PXIe8135) with WIndows 7.

We are developing application based in some labview timed loop work in parallel with external DLL (c, mingv based) . DLL was imported in Labview.

External DLL create some thread but this in Labview working sloowely.
Maybe labview different schedule internal dll THREAD ?

Hi.

If i can help you, i have seen that in veristand or in labview timed loop has a higher priority than while loop.
I thonk the thread created in the dll is similar to a while loop.

So the fact that dll thread executes slowly is not strange.

Try to replace timed loop by while loop and check the priority and also the call parameters of the dll node (run in other thread is better than run in ui thread in ypur case).

Best regards.

Hi

By default the Call Library Function Node runs in the UI thread and is having to fight your application for time in that thread. try checking the Run in any thread checkbox and see if that helps your application
