A method for estimating component power usage using aggregate power usage data are provided in the illustrative embodiments. A power estimation model is received, the model correlating a factor of the component with an aggregate power consumption of a set of components during a period, the component being a member of the set of components, the component being a hardware device operating in the data processing environment and consuming electrical power, the factor being a characteristic of the component related to the consumption of the electrical power in the component. A value of the factor at a determined time is received. The value of the factor is applied to the power estimation model to generate an estimate of electrical power consumed by the component. The estimate is output as the estimated power usage of the component when the factor attains the value.

Estimating component power usage from aggregate power usage

A method for discovering thermal relationships in a data processing environment is provided in the illustrative embodiments. An output temperature of a cooling unit operating in the data processing environment is changed from a previous output temperature to a new output temperature. The difference between the previous and the new output temperatures is a change in the output temperature. A change in an ambient temperature proximate to a data processing system is measured. The change in the ambient temperature is a difference between a previous ambient temperature and a new ambient temperature. An expression that represents a relationship between the change in the output temperature and corresponding change in the ambient temperature is determined. The expression is used to determine a cooling correspondence between the cooling unit and the data processing system.

A method of processing audio information for broadcast to an audience can include changing first audio information from occurring in a first time interval to occurring in a second time interval to provide time-changed audio information. The time-changed audio information can be combined with second audio information that is responsive to the first audio information to provide broadcast audio information.

The invention is directed to a method of and apparatus for initiating a duplex communication in response to a received simplex communication. In one embodiment of a method of converting a simplex communication to a duplex communication a simplex message is received; a duplex communication protocol is transmitted in response; and a duplex communication is initiated based on the response. In another embodiment of a method of converting a simplex communication to a duplex communication, a simplex message from a sender is received that includes the sender's simplex ID. A duplex communication protocol associated with the sender's simplex ID is sought, and a duplex communication based on the duplex communication protocol is initiated when the protocol is received.
