DF working on more processor cores at once?
« on: July 04, 2012, 02:55:45 am »
As the topic says...

Is this possible? My friend and I are complaining that DF works only on one processor core at once. Is there an utillity to set more cores on Dwarf?

Thanks.

No, it's not possible, till Toady rewrites whole DF from scratch to support multithreading.

I just saw a guy with two broken legs push a minecart with a corpse in it. Yeah.

This has been covered many times on the forums.  Use the search for more information.

Nearly every program you run on your computer, especially games, only use one core.
Making a program truly multi-threaded is a non-trivial task, and leads to difficult bugs, especially in languages like C/C++.

That said, keeping SDL rendering and user input in a separate thread is (last I heard) already implemented, and those are the most important.

Moving pathfinding, or AI, to a separate thread may be possible, but Toady only has 24 hours in each day.  It's a matter of return on investment of time, and converting a program from single to multi is tedious.
