Hi,

Via concurrent logic programming, and the
The Fifth Generation Computer Systems
10-year initiative launched in 1982 by Japan:

Fifth Generation Computer Systems (FGCS)
https://en.wikipedia.org/wiki/Fifth_Generation_Computer_Systems

There is a big fundus of material about
relating logic progra execution to parallel
execution. Unfortunetly the topic somehow

lost steam, and has been reduced to Remote
Procedure Call (RPC) of iterators inside the
Web Prolog initiative. But its evident that

this leads to nowhere, on modern CPU and GPU,
since RPC adds an additional comms aka message,
already to only communicate success or failure.

The other comms aka messages approach stems from
implementing parallel query executors for
relational databases and uses messages for

other things. It had already revival in 2008:

Just google MapReduce!

Bye
