Speed Test: Comparing Intel C++, GNU C++, and LLVM Clang Compilers

Nerval's Lobster writes "Benchmarking is a tricky business: a valid benchmarking tries to remove all extraneous variables in order to get an accurate measurement, a process that's often problematic: sometimes it's nearly impossible to remove all outside influences, and often the process of taking the measurement can skew the results. In deciding to compare three compilers (the Intel C++ compiler, the GNU C++ compiler (g++), and the LLVM clang compiler), developer and editor Jeff Cogswell takes a number of 'real world' factors into account, such as how each compiler deals with templates, and comes to certain conclusions. 'It's interesting that the code built with the g++ compiler performed the best in most cases, although the clang compiler proved to be the fastest in terms of compilation time,' he writes. 'But I wasn't able to test much regarding the parallel processing with clang, since its Cilk Plus extension aren't quite ready, and the Threading Building Blocks team hasn't ported it yet.' Follow his work and see if you agree, and suggest where he can go from here."

DIe Buisness Intelligence DIE

What on earth does compiler benchmarking have to do with the BI section of slashdot?

Furthermore, why on earth are you idiots creating a blurb on the main screen that just links to a different slashdot article? Its such terrible self promotion. Just freaking write the main article as the main article. No need to make it seem as if the Buisness Intellegence section is actually worth reading, its not.
