Intel's new compilers optimize for Hyper-Threading
According to this story
over at The Inquirer, Intel has released a new version of its C++ and Fortran compilers for Windows and Linux that optimize for Hyper-Threading. The new compilers pour over lines of code looking for opportunities to parallelize tasks and take advantage of Hyper-Threading's additional logical processor. The more applications are optimized for parallel execution, the better Intel's Hyper-Threading Pentium 4s should perform. As an added bonus, any parallel execution optimizations should also give users of real dual processor systems a healthy performance boost.
