How to control the number of CPU cores used by POT? #384
Description
Describe the bug
It seems that for some functions of POT, all the CPU cores available for the machine will be used. How can I control the number of CPU cores to be used? For example, if the computer has 20 CPU cores, all of them will be used by POT, how can I control only part of them (such as 10 CPU cores) being used?
