>From memory, Haney published such a comparison between F90, C++ and F77 a
couple of years ago in Computers In Physics. F77 compilers produced the
fastest-executing code. However, several of his tests showed C++ quicker
than F90. A search of their back issues should uncover this article.
For web sites, you might try and sarch for Veldhuizen's (sp?) at the
University of Waterloo. He claims quite rapid execution for his Blitz
library/templates.
Regards,
Dave.
