Abstract
Embodiments relate to a system, program product, and method for leveraging thermal profiles of processing tasks to dynamically schedule execution of the processing tasks. Thermal profiles of the processing tasks are generated, where the thermal profiles include core hardware and core processing measurements and predictions of thermal performance based on the measurements. The execution of the processing tasks are scheduled in processing devices to mitigate a potential for reducing a margin to a hardware thermal limit.
Claims20
A computer system comprising:
- one or more multi-core processing devices, each multi-core processing device of the one or more multi-core processing devices comprising two or more cores, the two or more cores configured to process one or more first instances of one or more processing tasks and one or more second instances of the one or more processing tasks;
- one or more memory devices operably coupled to the one or more multi-core processing devices;
- one or more hardware thermal counters coupled to each core of the two or more cores;
- one or more core processing performance counters coupled to each core of the two or more cores;
- and
- a scheduler module residing within the one or more memory devices, wherein the one or more multi-core processing devices are configured to implement the scheduler module, the scheduler module configured to:
