1. A method, comprising: performing rate-controlling data processing operations by a particular apparatus to stay within a heat budget for performing said data processing operations based on one or more heat price tags associated with said data processing operations, wherein said performing rate-controlling data processing operations includes: determining, by the particular apparatus, to delay performing a particular next scheduled non-latency sensitive or low-priority operation of said data processing operations in response to a particular heat price tag associated with the particular next scheduled non-latency sensitive or low-priority operation that would not allow said data processing operations to stay within a predetermined additional heat budget margin below the heat budget if the particular next scheduled non-latency sensitive or low-priority operation is performed prior to a time delay, with said heat budget margin providing a heat margin such that a low-latency or high-priority operation of said data processing operations may be performed prior to a next scheduled non-latency sensitive or low-priority operation if performance of the low-latency or high-priority operation will allow said data processing operations to stay within the heat budget; in response to said determining to delay performing the particular next scheduled non-latency sensitive or low-priority operation, the particular apparatus performing a particular latency sensitive or high-priority operation of said data processing operations while staying within the heat budget; and subsequent to said performing the particular latency sensitive or high-priority operation of said data processing operations, performing the particular next scheduled non-latency sensitive or low-priority operation in response to the particular heat price tag associated with the particular next scheduled non-latency sensitive or low-priority operation allowing said data processing operations to stay within the predetermined additional heat budget margin below the heat budget.
