How to speed up ladybug fly computing?

I have 30 programs that need to be run one by one, but the computation time is too long if I use a ladybug fly for control. How can I divide the 30 programs into 3 groups, each group running 10 programs each, and these 3 groups can run different programs at the same time. Thus reducing my calculation time to a third of what it was. Is there any program that can help me to achieve this?
