Prioritizing power delivery to processing units using historical workload information

A computing system comprising:

• a plurality of power supplies;
• and
• a plurality of processing units, wherein a first set comprising a first processing unit of the plurality of processing units is configured to:
• distribute computing workloads among a second set of the plurality of processing units;
• responsive to detecting a reduced power supply capacity of the plurality of power supplies:
• determine, based on historical workload information reflecting one or more previously completed workloads, a first workload of the computing workloads to prioritize the completion thereof;
• and
• prioritize power delivery to a selected processing unit of the second set to which the first workload is distributed;
• and
• power down the selected processing unit responsive to completion of the first workload.

A computer program product for distributing power among a plurality of graphics processing units (GPUs) of a computing system, the computer program product comprising:

• a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code executable by one or more computer processors to perform an operation comprising:
• distributing computing workloads among the plurality of GPUs;
• responsive to detecting a reduced power supply capacity of the computing system:
• determining, based on historical workload information reflecting one or more previously completed workloads, a first workload of the computing workloads to prioritize the completion thereof;
• and
• prioritizing power delivery to a first GPU of the plurality of GPUs to which the first workload is distributed;
• and
• powering down the first GPU responsive to completion of the first workload.
