Execution Properties Page

Select File»VI Properties and select the Execution page from the pull-down menu.

Use this page to set execution properties.

Refer to the Using LabVIEW to Create Multithreaded VIs for Maximum Performance and Reliability Application Note for more information about execution properties and reentrant VIs.

The Execution page includes the following components:

If another VI with higher priority calls this VI, the priority of this VI rises to match the priority of the calling VI. The priority of this VI never drops below the level you set in this dialog box.

Selecting subroutine priority tells the LabVIEW execution system to run the VI as fast as possible and never let any other VIs have any time. It also prevents any screen redraws and other system functions from occurring. You cannot abort a VI that has subroutine priority.

Normally, you set all VIs to run in the same execution system as the caller. To use an alternate execution system for a set of VIs, set the top level VI to that execution system, and all sub VIs will run in that execution system also.
