Hi Dirk,
Dunno what the best is. I use VS .NET 2003 but one compiler's enough for
me. I couldn't afford Intel C++ as well but from everything I read
(non-Blitz++ related) the Intel compiler is usually better. FWIW in my
inner loop I moved away from Blitz++ and do it all with inline SSE now. I
also removed all function calls and inlined them instead. This was as a
result of profiling. I don't know offhand if any compilers will generate
SSE code for you. For me development time isn't really an issue - inlined
SSE development is almost as fast as C++ development.
