Although SMP is an abbreviation for Symmetric Multi-Processing (multiple processors or processor cores with shared memory), SMT is not symmetric but Simultaneous Multi-Threading. To get back on topic, SMT is often confused with barrel processors that switch threads between clock cycles, like the Honeywell 800 with special register groups. The "simultaneous" in SMT means that a single processor core runs instructions from multiple threads on the same clock cycle.
