Intel Releases Compiler Suite 7.0
Yokaze writes "Intel boosts its Pentium 4 and Itanium 2 and released Version 7 of its compiler suite. On the Windows side, there is the plugin compability to the .NET enviroment, on the Linux side better compability to the GNU compiler, including the Common C++ ABI.
As usual, there are 30-days evaluation copies and for Linux an unsupported non-commercial version after previous registration at the Intel Evaluation Centre. According to the comments published by Intel marketing, Dr. Fons Rademakers, CERN, claims high compability with GCC 3.2 and a performance increase of up to 30% on their code (The ROOT System)."

I just downloaded the new intel compiler for windows. Tested it with a opengl application I made that runs really slow. The difference between the microsoft c++ compiler and the intel one is about 15%. Not quite 30%, but that probably applies to particular situations...

It's not in CVS yet (server down, other issues), but Linux from Scratch builds GCC 3.2.1 for most people out of the box with the same commands as 3.2. Also, many have reported that they have built LFS with glibc 2.3.1, and have experienced huge speed increases. I know a few on the IRC channels who have successfully built glibc 2.3.1 with no changes to the commands used in LFS 4.0. Note that GCC 3.2.1 is required for glibc 2.3.1.

Gentoo has a package for icc, as well as gcc. BTW they had a working autobuild for gcc 3.2.1 two days before the slashdot announcement of the release

Just for peoples reference, I came across these patches for the FreeBSD kernel (LINT) to get it going with icc.
I haven't tried them yet but I would love to see the whole of FreeBSD compiled with icc. The speed increase would be very cool.

It's doubtful that compiling any OS kernel with Intel's compiler will result in significant speed increases. Most architectural optimizations that the Intel compilers make that gcc doesn't lie in the area of SIMD instructions, and instruction scheduling to maximize pipelining, parallelism, etc. It will be very useful in areas such as graphics, multimedia, other heavy-duty computation, and the like, but not in a general purpose OS, where the instructions are mainly loads and stores of data.
