Deallocate memory as soon as possibleDeallocates the memory of every VI after the VI runs. This option can improve memory usage in some applications because subVIs can deallocate their memory immediately after running. However, this option significantly slows performance because LabVIEW must allocate and deallocate memory more frequently. In some instances, deallocating memory might lead to excessive memory fragmentation.
Use default timerToggles use of the default timer.
Check available disk space during launchReports the amount of disk space available in the temporary directory as LabVIEW starts.
Note Changes to this option take effect the next time you start LabVIEW.
Abort if less than (Kbytes)Indicates the minimum amount of disk space needed to run LabVIEW. If less than this amount of disk space is available, LabVIEW aborts its launch. If you place a checkmark in the Use default option, you cannot edit this field.
Use defaultSets Abort if less than to its default value of 500 KB.
Warn if less than (Kbytes)Indicates the preferred minimum amount of disk space needed to run LabVIEW. If less than this amount of disk space is available, LabVIEW warns you and continues its launch. If you place a checkmark in the Use default option, you cannot edit this field.
Use defaultSets Warn if less than to its default value of 2,000 KB.
Run with multiple threadsEnables multithreading. This option is available only on operating systems that support multithreading. If you remove the checkmark from this option, the execution system behaves as though you have only a single thread. Single thread execution removes some overhead from the execution system. However, you do not benefit from the advantages of multithreading, such as multiple processor support and the ability for a higher priority operation to interrupt a long operation (such as a screen redraw) to get better responsiveness from the application. Remove the checkmark from this option for VIs that are not compatible with a multithreaded execution system.
Note Changes to this option take effect the next time you start LabVIEW.
Compact memory during executionMacintosh Compacts memory approximately once every 30 seconds. This reduces fragmentation by moving allocated memory to adjacent locations. However, this option might slow performance because LabVIEW must compact memory more frequently.
Cooperation levelMacintosh Controls how cooperative LabVIEW is with other background applications. If you select Low, LabVIEW does not share time very frequently with other applications. This improves the performance of LabVIEW but slows the performance of any other applications that run in parallel. If you select High, LabVIEW performance slows, but other applications have more time to run.
