[FEATURE] Improve job scheduling when a function uses pytorch

[badmonster0]

What is the use case? Currently we're using a global mutex to make one function (using pytorch) is executed at a time, to avoid conflicts. We should improve the scheduling strategy.

Describe the solution you'd like We may try to use multiprocessing for this.
