Job agent-based power-capping of systems

A non-transitory storage medium that stores machine-readable instructions that, when executed by a first node, cause the first node to:

• acquire node performance data while a job associated with an application is being concurrently executed by a plurality of nodes containing the first node, wherein the plurality of nodes is power-capped by an existing node power consumption budget, and acquiring the node performance data comprises the first node receiving data from nodes of the plurality of nodes other than the first node;
• determine, based on the performance data, a performance footprint associated with the application, wherein the application transitions through multiple stages, and the performance footprint characterizes a current stage of the multiple stages;
• and
• determine whether to request a change to an existing node power consumption budget based on the determined performance footprint and a predefined power consumption policy.

An apparatus comprising:

• a processor associated with a first node of a plurality of nodes, wherein the plurality of nodes is associated with a job, the first node executes a leader instance of an agent, and each node of the plurality of nodes other than the first node executes a follower instance of the agent;
• and
• a memory to store instructions that, when executed by the processor, cause the processor to:
• communicate with the follower instances to acquire node performance data about the job while the job is being executed by the plurality of nodes;
• determine, based on the performance data, a performance footprint associated with the job, wherein an application is associated with the job, the application transitions through multiple stages, and the performance footprint characterizes a current stage of the multiple stages;
• and
• determine, based on the performance footprint, whether to request an increase in a node power consumption budget relative to an existing node power consumption budget from a power pool or return part of the existing power consumption budget to the power pool.
