State of research
- SMT is simulated and evaluated with Spec92, Spec95, and with database transaction and decision support workloads
- Mostly unrelated programs are loaded in the thread slots!
- Typical result: 8-threaded SMT reaches a two- to threefold IPC increase over single-threaded superscalar.
State of industrial development
- DEC/Compaq announced Alpha EV8 ( 21464 ) as 4-threaded 8-wide superscalar SMT processor
