In mid June Intel released Version 9 of its C++ and Fortran
compilers. The new version of compilers is not principally different
from previous Version 8.1. Its main features are compiler integration
for IA-32, IA-64, and EM64T (x86-64) platforms into a unified package
and additional options for processors with Hyper-Threading and
multi-core processors as far as code optimizations are concerned. In
particular, Software-based Speculative Pre-Computation (SSP).
In this article we shall analyze how fast the new version of compilers
is compared to the previous version on top (or almost top) single core
processors — both from Intel (Pentium 4 and Pentium M) as well as...
from AMD (Athlon 64 FX-57 — of course, with some code adjustments, see
below). Read on at Digit Life.
