Using dynamic global policies in power and energy management on high performance computing platforms

A computer system comprising:

• a processor;
• and
• a storage device storing instructions which when executed by the processor comprise instructions to:
• determine a metric associated with power and energy management in a high performance computing (HPC) system,
• wherein the HPC system comprises a plurality of nodes running a plurality of jobs, wherein a respective node comprises one or more processing elements, and wherein the metric is based on a factor which is configurable, an amount of energy consumed by the HPC system, and a runtime associated with the plurality of jobs;
• calculate the metric at predetermined time intervals;
• identify a global policy for providing power to the HPC system;
• determine that a change is to be made to the global policy;
• and
• change the global policy dynamically by:
• configuring the factor in the metric to a value which corresponds to a new global policy;
• and
• setting, based on the configured factor, an assigned power per processing element corresponding to a minimum of the metric.

A non-transitory computer-readable medium storing instructions to:

• determine a metric associated with power and energy management in a high performance computing (HPC) system,
• wherein the HPC system comprises a plurality of nodes running a plurality of jobs, wherein a respective node comprises one or more processing elements, and
• wherein the metric is based on a factor which is configurable, an amount of energy consumed by the HPC system, and a runtime associated with the plurality of jobs;
• calculate the metric at a predetermined time interval;
• identify a current global policy for providing power to the HPC system;
• and
• dynamically change the current global policy to a new global policy, which comprises:
• configuring the factor in the metric to a value which corresponds to a new global policy;
• and
• setting, based on the configured factor, an assigned power per processing element corresponding to a minimum of the metric.
