Abstract: A cooling system controller for a set of computing resources of a data center includes a first interface to couple to a first flow controller that controls a rate of thermal energy transfer to a PCM store from the set of computing resources, a second interface to couple to a second flow controller that controls a rate of thermal energy transfer from the PCM store to a cooling system, and a controller to determine a current set of operational parameters for the data center and to manipulate the first and second flow controllers and via the first and second interfaces to control a net thermal energy transfer to and from the PCM store based on the current set of parameters.

Abstract: A heterogeneous processing device includes one or more relatively large processing units and one or more relatively small processing units. The heterogeneous processing device selectively activates a large processing unit or a small processing unit to run a process thread based on a predicted duration of an active state of the process thread.
