Parallel program not using more than 1 CPU

Sorry did that after.

But then a comment to the code, are you only interrested in the last value for each column that is above the threshold?

Reemeber that LabVIEW 2012 has the conditional tunnel, which allows you to do basically the same, but parallelize the loop. 😄

With the default settings, it executes in 130ms on a single core but in 10ms with the parallel FOR loop. (16 core dual xeon). Seems significant!

(You also really need to disable debugging on the VI. I also think you forgot the conditional terminal in the innermost loop.)

The i7-3820 has only 4 hyperthreaded cores (8 virtual cores, but that's not really significant). You will not get much more than 4x out of it.
