Hello,
This may be a silly question, but I have setup a process that is supposed to take advantage of the Parallel Processing Extension, but I don't see any way to determine if it is actually doing so properly. I'm looking at the number of cores being used by my machine and I don't see all of them working. I know in previous versions of RapidMiner, if I used the X-Val (Parallel) process, the display would show parallel processes as being separated with a "|" character, ie: ForwardSelection>>[1]Xval(Parallel) | [2]XVal(Parallel) | [3]XVal (Parallel), etc. Here is my process:
