ITT:People who never set fps=0 and gfps=5 in the init.txt

[fanatic]

Who cares?

I'm hoping that since improved pathfinding is number 3 in the Eternal Suggestions, we'll see marked improvements once that's addressed.

Hope - is a stupid feeling

Regarding the two of the top ten ESV items not specifically addressed on the new page, sped-up pathfinding and graphics support, the idea with the first is an upcoming date with the linux profiler now that we've got DF running over there to address the low-hanging fruit on the main grievance behind the suggestion (large, slow forts).

Ha!

Two moths and five bugfixing releases later

I'll probably start out in August with the site sprawl over the world map and keep up with that for as long as it takes to allow adventurer sites and the other things that come out of it.

Nothing about optimization in the forseeable future. I guess he doesnt want to do it but doesnt have the guts to say it outright. So yeah hope here is pointless. Just saying. Sorry for necroing the thread.

Momma always said not to feed the Trolls, but I don't listen too good...

I guess your feelings got hurt because your pet peeve wasn't directly addressed, and you lack the emotional maturity to not whine about it.  So yeah, hope for useful posting here is pointless.  Just saying.  Sorry for feeding the troll.

Just tried to callgrind one of my bigger forts with that binary with symbols.
80.9% time - moveunits()
74% time - moveunit() (called from moveunits())
15.58% time - update_health() (called from both moveunit() and moveunits())
4.45% time - shoulddie()
5.57% time - contaminant_advance()
4.46% time - assignjobs_des()
1.75% time - advancebuildingstates()

I'm too lazy to properly analyze results right now (there are about 2000 functions), but even quickly looking at results i see that healthcare is definitely eating more than it should, for example. And moveunit() has very obscure call-graph, seems it triple-checks each path before actually moving.
So as i said before, theres alot of space for optimization even with single-threaded style and same pathfinding

mmmmm.  I would love to optimise DF, lots of juicy cycles to save.
I guess the fun's all Toady's though.  I'll go change my vote on the eternal suggestions list, give him something to look forward to :O.

[ungulateman]

I think update_health is keeping track of creature's injuries and missing body parts, rather than healthcare. It's bloated by the fact it keeps track of dead creatures even when they've rotted away, as well.

[Neonivek]

And I don't mean because it's 20 years in the future and we all have quantum computers

No we are pretty close to having those kinds of computers now. Before Dwarf Fortress will even have its first version out (V1) we will have computers that can run it.

Technology is odd that way.

On that note, people in this thread are vastly underestimating the growth of computing power. At the current rate of growth, for 1000 USD, in 2030, it will be possible to buy a computer more powerful than a human brain. By 2050, every brain combined. By 2080, every human brain ever.

Lately computing power has been growing in a way that's not compatible with DF: multiple cores. Who's to say DF will ever capitalize on future improvements?

[Urist McDepravity]

At the current rate of growth

Growth? Somehow I didn't notice any since 2003.
Yeah, they keep stuffing more cores in single CPU now, but thats extensive path, and the one which cannot be utilized by DF (lack of multithreading).

So you're saying that DF won't run on a multicore computer?I am running a quad core and it runs DF fine.

[nbonaparte]

There's more than silicon. There's still a lot of room to go smaller before you need multiple cores. We're approaching silicon's limits, so we're beginning to do the multicore thing. But I will agree that to keep up, Toady will eventually have to implement multithreading.

Gah, ninjas! Eh, I've already written the response.

[Mazonas]

I can confirm that an i5 750 processor allows DF to be played at high FPS even at high population counts.  Not mine sadly, the other half's.  I'm stuck with a dual core processor that sucks for DF at the moment.

Expensive solution, but I plan on saving up for one.

Erm, how is that possible? Ex.: Isn't a E8400[dual core / 3Ghz] is better for DF than the i5 750[quad core / 2.66Ghz]? DF isn't using multiple cores afterall...

[Mazonas]

I assume it is the quality of the cres themselves.  I know the OH restricts 1 of the cores just for DF

Core i3/i5/i7 series are more efficient than earlier processors so it wouldn't surpise me if 2,66Ghz > 3Ghz.
