My Mac seems to have a relatively old version of gcc:
$ g++ -v Using built-in specs. Target: i686-apple-darwin8 Configured with: /private/var/tmp/gcc/gcc-5367.obj~1/src/configure --disable-checking -enable-werror --prefix=/usr --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg][^.-]*$/s/$/-4.0/ --with-gxx-include-dir=/include/c++/4.0.0 --with-slibdir=/usr/lib --build=powerpc-apple-darwin8 --with-arch=nocona --with-tune=generic --program-prefix= --host=i686-apple-darwin8 --target=i686-apple-darwin8 Thread model: posix gcc version 4.0.1 (Apple Computer, Inc. build 5367) c-24-6-157-150:~ skybrian But I just installed Xcode 2.4.1 which included a gcc upgrade, so apparently this is current on OS X. I'll have to figure out how to use Xcode and Shark. - Brian On 2/22/07, Łukasz Lew <[EMAIL PROTECTED]> wrote:
I do not understand it. Maybe someone does? I've made some tests on 2 core processors, and I have strange results. Some of 2 core processors got results exactly 2x times worse than they should. Why? I have no idea. But 2.8 Ghz 2 core works exactly like my 1.4 laptop. Also version of g++ does matter.
