Constantine, as you may or may not know, HyperThreading is a form of SMT that allows one processor to execute two threads at the same time. The pipeline and execution resources are shared between the two threads, unlike other processors that have to do context switches to go from one thread to another. However, if one of the threads does a lot of useless work, the performance of the other thread (probably doing useful work) could suffer. The solution is twofold: 1) Put SMT-aware functions in standard libraries and have programmers start using them. 2) Have the compiler produce SMT-friendly code (i.e. code that doesn't waste execution resources that it could afford to lose in single-threaded mode).
