Parallel Iterations: Improving For Loop Execution Speed

You can improve the execution speed of a For Loop by enabling parallel iterations. LabVIEW normally partitions For Loop iterations into chunks and executes them sequentially. When you enable parallel iterations on a For Loop, LabVIEW executes chunks simultaneously, improving the execution speed of computationally intensive For Loops.
Complete the following steps to execute For Loop iterations in parallel:
- Enable parallel For Loop iterations.
- Verify that the For Loop can run with parallel iterations.
- If necessary, programmatically configure parallel For Loop iterations.
Review the performance considerations to ensure that a For Loop will benefit from parallelization.
Examples
Refer to the Parallel For Loop Reduction VI in the labview\examples\Structures\Parallel For Loop directory for an example of using a For Loop with parallel iterations.

Not all For Loops can run with parallel iterations. Check for a set of errors and warnings that prevent a For Loop from running with parallel iterations.
