This is going to be interesting ... perhaps.

I'm currently compiling the version of gcc I used to use with kubuntu.. interesting as it has a proper -march=core2 optimisation flag and it's the experimental branch for autovectorisation..

Although I think a lot of the previous av branch changes have been merged with mainline, it has resulted in some good performance increases for kubuntu on my x2 4400.. so it will be interesting to see what the likes of openoffice and stellarium etc will give on my MBP as they did give pretty good results before

Before anyone says anything.. the xcode gcc version does not understand what a core2 is thus does not have native support..

I might have to look at compiling PoV then running the standard examples as a benchmark.

twiddles thumbs... fans@6,000rpm captain and she's holdin' steady@63degC.

While the coreduel autowaving star field does work, does it not void the EULA and is missive about the massive transfer of electron particles through the PSYCHO KILLER HAWKING ether? Can't you just use OS X like the rest of us?

I've got a Computer Science degree and it still makes no sense

Something about an compiling an experimental version of gcc that allows him to specify his machine architecture as dual-core and thus take full advantage of his cpu's?? :confused:

Yeah but there's something about Core2's and AMD processors in there. Mutually exclusive that is.

currently the POV 3.7beta is being a PITA...

BOOM, Mr Jobs says:

Code:

Most inconsiderate.. looks like there's a very subtle library difference...

I think you'll find you're missing a ~ there....

... possibly a threading issue... well that's what you get with beta software!

Slogan · 1 Apr 2008 at 22:00

I was only joking.

I've no idea what you posted at all. Looks good though.

Got it working my setting the architecture type to i386 in the POV build.. so that 32bit! The issue is todo with 64bit app vs 32bit library (so the system isn't getting it right or there's a bug in the 64bit version of the Xcode GCC 4.0.1..).

Roll on..
