Abstract
Simultaneous multithreading (SMT) is an architec-
tural technique in which the processor issues multiple
instructions from multiple threads each cycle. While SMT
has been shown to be effective on scientific workloads, its
performance on database systems is still an open question.
In particular, database systems have poor cache perfor-
mance, and the addition of multithreading has the poten-
