A bit of additional testing, re: Intel vs. gcc

[Scott Robert Ladd]

I'm getting solid feedback from the Intel C++ vs. gcc benchmarks I published
yesterday. Thanks to those who've given me suggestions and ideas.

Today, I've had a chance to get both compilers working on a piece of
in-house production code: an 11,000-line simulation. Compiled with Intel C++
7.0, a deterministic "run" takes 6:23 minutes; when compiled with gcc 3.2.1,
the run executes in 5:28.

According to profiling, the Intel compiler is still limited by the
performance of its vector<> (the C++ template) implementation -- showing
that it isn't just code generation that affects program performance.
