You should have gone down the street earlier this week to the SIAM conference on
parallel processing for scientific computing, and asked there. There are some people
that go straight C++, but for the most part, the people that want to use C++ and are
serious about high performance will put C++ wrappers around the Fortran computational
kernels to get the high performance of Fortran. And of course, most scientists still
use Fortran as the sole language.
I think there are some comparisons out there, but I don't have the locations.
