Method and apparatus to maintain node power budget for systems that share a power supply

A method for use with a plurality of nodes that share a common supply of power, the method comprising:

• receiving, by a first node of the plurality of nodes, a first indication;
• and
• in response to the receiving the indication, the first node temporarily performing power capping regulation for the plurality of nodes, including running power capping regulation logic to generate power control information to regulate power in the plurality of nodes including the first node and sending the power control information to nodes in the plurality of nodes other than the first node.

An article of manufacture having one or more non-transitory computer readable media storing instructions which, when executed by a system, cause the system to perform a method for use with a plurality of nodes that share a common supply of power, the method comprising:

• receiving, by a first node of the plurality of nodes, a first indication;
• and
• in response to the receiving the indication, the first node temporarily performing power capping regulation for the plurality of nodes, including running power capping regulation logic to generate power control information to regulate power in the plurality of nodes including the first node and sending the power control information to nodes in the plurality of nodes other than the first node.

A method for use with a plurality of nodes that share a common supply of power, wherein each of the nodes is operable to run power management logic, the method comprising:

• each of a plurality of nodes receiving power from a power supply unit shared by the plurality of nodes;
• and
• each of the plurality of nodes running power management logic for a period of time to generate power control information to perform power regulation for itself and other nodes in the plurality of nodes, such that only one of the plurality of nodes is performing power regulation for the plurality of nodes at any one time.
