Which is faster nowadays when running Parallel Algorithms?
ATI, or Amazon?
Added
The problem to solve is larger in scale than both of them;
Take costs into consideration.

Amazon is definitely faster if you have an operation and can't be parallelized much beyond the number of....
If you have most on how parallelizable your code is .
It depends! Amazon will probably be faster than any single video card or GPGPU.

I understand why it does that but I don't really have any idea of how to prevent that. So the scenario is, every frame I move the car by a certain of predefined pixels. What happens is when I go on slow or faster computer... well I get less or more frames...

Save the time after all calculations.
You have to save the time before moving car and drawings .
Car model should be independent of the display representation.
Move car according to timers and not framerate.

So... which one is faster (NULl value is not an issue), and are indexed.
SELECT * FROM A JOIN B b ON b.id = a.id JOIN C c ON c.id = b.id WHERE A.id = '12345'
Using Left Joins:
SELECT * FROM A LEFT JOIN B ON B.id=A.bid LEFT JOIN C ON C.id=B.cid WHERE A...

The JOIN syntax.
They probably both execute about the same.
Differently (and become faster) as well.

I read somewhere that snprintf is faster than ostringstream. Has anyone has any experiences with it? If yes why is it faster.
Answer Snippets (Read the full thread at stackoverflow):
That's right i think.
Family of functions are faster than the corresponding C++ functions (cout, cin, and other streams that the functions can't be faster than each other, but their implementation can.

Runners... trying to get faster... lengthen my stride or turn 'em over faster? I have been biking for many years... playing with some of the shorter duathlons and triatlons. I quite enjoy them, but MAN, my run is weak!
I have been working on the run for...

If you want to get a longer stride doesn't make any sense at all .
Work on getting faster doing speedwork like intervals.

I know that performance never is black and white, often one implementation is faster in case X and slower in case Y, etc. but in general - are B-trees faster then AVL or RedBlack-Trees? They are considerably more complex to implement then AVL trees (and...

In fact, if key....
Because the lookup is binary it's very easy to find in memory .
So B-trees will probably be faster if you cases I'd say that in-memory RB trees are faster.
RB trees are used when you don't have this constraint .
Expensive.

BTW, why Python and not Haskell? Haskell is 100x faster than PHP in some benchmarks.

But even though Python is ~4 times faster, by and large it's the architecture maintaining two.

Is var x = new Stuff(); x.DoStuff(); faster than new Stuff().DoStuff(); ?
I'm not sure why but I noticed in my code that the first method makes it faster, anybody knows which one is faster and why ?

Actually the second should be faster.
About (the difference was 0.8 ms on one million iterations) .
