Hi,
I cannot make Zorro S use more than 1 CPU core during TRAIN mode, with or without Walk Forward.
This command has no effect:
if(is(INITRUN)) NumCores = -1;
No matters the number I assign to NumCores, the total CPU usage is around 15%. And I can see just one CPU running with Resouce Monitor.

Are there code restrictions to enable multi-core processing?

I'm using Zorro S 1.96 in an Intel i7 PC.

Thanks in advance.
