Abstract:
A program product and method of managing task execution on an integrated circuit chip such as a chip-level multiprocessor (CMP) with Simultaneous MultiThreading (SMT). Multiple chip operating units or cores have chip sensors (temperature sensors or counters) for monitoring temperature in units. Task execution is monitored for hot tasks and especially for hotspots. Task execution is balanced, thermally, to minimize hot spots. Thermal balancing may include Simultaneous MultiThreading (SMT) heat balancing, chip-level multiprocessors (CMP) heat balancing, deferring execution of identified hot tasks, migrating identified hot tasks from a current core to a colder core, User-specified Core-hopping, and SMT hardware threading.
