Intel released its version 7.0 compiler suite for Linux and Windows, for the x86 and Itanium1/2 architectures. Optimizations include support for SSE2 in the Pentium 4 CPU and software pipelining in the Itanium1/2 CPUs. Inter-procedural optimization (IPO) and profile-guided optimization (PGO) can provide greater application performance. Intel Compilers support multi-threaded code development and optimization through the Auto-Parallelism feature and OpenMP 2.0 support. Intel claims that the new version of their compilers are now much more compatible with Linux code (including the GCC C++ ABI) and that they also outperform GCC 3.2 by 30% at the produced executables. There is a 30-day evaluation version for everyone to try out.
Windows and Linux versions are available. The full version is $399 and can be purchased at their online store.
