[SercoSteveB]

What does the For Loop 'P' Terminal, identified by the arrow, indicate?

a) That the loop is configured for parallel execution

b) That each iteration of the loop will pause for the duration, in milliseconds, passed to the terminal

c) That the loop is configured to run as a While loop

d) That the loop will pause when the iteration count terminal reaches the value passed to the terminal

Has anyone got a use case for Parallel For Loop execution?

[JGmitter]

Only use case I can see is performance increases.  I have not used this yet but I probably should be.  See link.

I haven't used them myself, but I hear from some people where they are good for massive computations.  The CLA-R prep material has a question where the computing of FFTs are the best choice for parallelization.

[LordNobady]

as a use case I think some calibration on single array values can be used.

lets say you have an array of collected analog data that to get the correct working value needs some single elements calculations ( lets say an offset and a factor )

by Paralizing you can use all the machine's CPU's to calculate it. ( is mostly interesting with more time consuming actions )

[mini09]

Agreed A as well... I`m not used parallel for loop...
