I'm always surprised by that myself. I routinely do stuff like writing
an application in a "scripting" language and putting the CPU intensive
stuff into C subroutines, and every once in a while (usually while OS
hacking since the compilers are now very good) one throws an asm()
statement or .S file into the mix.
I think part of the issue is that most people doing scientific
computing don't have computer science backgrounds, which is a
