Haim,

I would admit that few developers use Intel's compiler to build 100% of the application (i.e. exclusively). However, I will stand behind the statement that I made before that A LOT of software uses the Intel compiler for key performance parts (i.e. you might have your performance critical functions in a single or couple of source files that are compiled with the Intel compiler and then linked under MS VC with the rest of the sources - A VERY COMMON practice).

I can buy the use as a plug-in for specialized app and your other reference of Direct3D. These require distribution of multiple executables to address different flavors of MMX/SSE/3Dnow, which very few companies do. It's probably similar to how companies used assembler: rarely and handled with extreme care.

Debugging of the C++ code is enough of a nightmare, and throwing in another unknown is a risk few companies can afford.

Joe

Since the SPECfp code is written in Fortran, that would require rewriting the critical code sections in Fortran. While that would be pretty easy with C, it would not be trivial for C++, and a lot more work then just recompilation.

Plus, of course, the Pentium 4 version of the Intel compiler is not for sale yet.
