Predictable performance in SMT processors: synergy between the OS and SMTs

Current operating systems (OS) perceive the different contexts of simultaneous multithreaded (SMT) processors as multiple independent processing units, although, in reality, threads executed in these units compete for the same hardware resources. Furthermore, hardware resources are assigned to threa...
