Abstract
The industry is rapidly moving towards the adoption
of Chip Multi-Processors (CMPs) of Simultaneous Multi-
Threaded (SMT) cores for general purpose systems. The
most prominent use of such processors, at least in the
near term, will be as job servers running multiple indepen-
dent threads on the different contexts of the various SMT
cores. In such an environment, the co-scheduling of phases
from different threads plays a significant role in the over-
