One example would provide for maximum throughput thus increasing capacity during times when only low and medium priority work is running while allowing for the shorter turn around times required by critical work. Moreover, it creates a "SMT Control Monitor" (SCM) which would examine the type of work running on the machine. This monitor would turn ON/OFF SMT feature, and suspend/resume job threads as the work load demanded. This idea is different than other SMT control disclosures because it incorporates information from the batch system. This additional information will be used to better manage the state of SMT and the job threads.
