How is "num_nodes" in the {{ num_nodes }} set? Can it be modified?

In the "config_batch.xml" file there is a variable "num_nodes". Is this modified automatically?
When I run the tutorial command for setting up a new case,
./create_newcase --case ~/cases/b.day1.0 --res f19_g17 --compset B1850
and then running ./case.setup, and ./case.build,
the "num_nodes" is automatically revealed as 6.

I think this is causing runtime error in the new machine upon running ./case.build.

Yes this is modified automatically based on the NTASKS and MAX_MPITASKS_PER_NODE values.

Thank you so much! I figured it out based on your suggestion
