Parallel processing in FPM is initiated by the process itself from its main thread by spawning child threads and once the child threads are running, main thread is monitoring their status and waiting till all child threads finish. Once finished, the main thread continues. It’s important to note that all parallel enabled processes in FPM share common code for both the main thread and child threads. This means that both are implemented by a single TI process.
The process enabled for parallelism must correctly distribute source data among the threads. It's crucial to ensure that no two threads write their results to the same data location.
