UmbralRaptop: Ah, I see

I love how finicky C++ optimizations are
<awang>
Replace a loop boundary with a compile time constant and add a "final" qualifier to a member function cuts runtime in half
<awang>
Granted, those are things that the compiler can't figure out on its own, but still
<awang>
It's amazing what little things are stopping the compiler

"The fundamental problem was their use of water vapor emissivities exceeding unity, which caused their model atmosphere to radiate more efficiently than a blackbody."
<awang>
Looks like one reason the small changes from yesterday netted such large speedups is because Clang still isn't as good as GCC with its optimizations
<awang>
One test Clang got about 210 seconds, GCC about 164
<awang>
That was before the optimizing changes
<awang>
I'm a little less optimistic about easy speedups now :(
<awang>
Erm

Clang is complaining about not being able to vectorize something due to a switch statement

Also, C scares me.

it's well worth writing at least a few programs in it UmbralRaptop, particularly if you get your head around pointers

UmbralRaptop, I like that this collection has papers for each week

Anyone here know how much I should expect branch prediction and other fun to mess with IACA results?
