As of gcc 2.9, athlon optimizations were crappy. I haven't tried gcc 3.2 yet. If you have a P4, you can use SSE2 to do fpmath arithmetics. Now Intel Fortran compiler is a different story. It BLOWS away g77! Even i686 compiled fortan code on an ATHLON is WAY faster with IFC than g77. The fact is Intel has a Fortran 90 compiler, which gcc currently don't have in a decent state for now.

[Cooker] icc - Optimization
Is any optimiziation planned for the Intel(R) Compiler. Thanks harrison3001
Re: [Cooker] icc - Optimization
What do you mean? 1. Does Mandrake plan to use ICC? No. It's not gpl, and Mandrake's goal is to be 100% gpl. 2. Does ICC have better optimizations than gcc? Hard to say. In my own experience (computational chemistry), I've found IFC compiled apps equal to or slightly slower than gcc. GCC has very good optimizations FOR INTEL. I dunno about AMD. As of gcc 2.9, athlon optimizations were crappy. I haven't tried gcc 3.2 yet. Now Intel Fortran compiler is a different story. It BLOWS away g77! Even i686 compiled fortan code on an ATHLON is WAY faster with IFC than g77. 3. Can you recompile Mandrake apps with IFC? Sure. 4. Would they be faster binaries than with gcc? Try it and let us know.
