I didn’t find any information about asynchronous programming in Prolog. So, how to use asynchronous programming in Prolog?

Do you mean [threads](https://www.swi-prolog.org/pldoc/man?section=threads)? Maybe [coroutines](https://www.swi-prolog.org/pldoc/man?section=engines)? What is your definition of “asynchronous programming”? I cannot find anything online that mentions “asynchronous” without mentioning threads, but those are so easy to find that it is very improbable that you didn’t find any information.
