    Abstract: Techniques for inducing non-uniform cooling are described. According to an embodiment, a system is provided. The system can comprise at least one processor device that executes components stored in a memory, wherein the components comprise: a flow control device that distributes coolant to a location of the at least one processor device; and a sensor controller component that detects a location of a thermal anomaly of the at least one processor device. The components can also comprise a cooling controller component that adjusts the flow control device to direct the coolant to the location of the thermal anomaly.

    Abstract: An aspect includes receiving a write request that includes a memory address and write data. Stored data is read from a memory location at the memory address. Based on determining that the memory location was not previously modified, the stored data is compared to the write data. Based on the stored data matching the write data, the write request is completed without writing the write data to the memory and a corresponding silent store bit, in a silent store bitmap is set. Based on the stored data not matching the write data, the write data is written to the memory location, the silent store bit is reset and a corresponding modified bit is set. At least one of an application and an operating system is provided access to the silent store bitmap.

    Abstract: According to one embodiment, a method for power management of a compute node including at least two power-consuming components is provided. A power capping control system compares power consumption level of the compute node to a power cap. Based on determining that the power consumption level is greater than the power cap, actions are performed including: reducing power provided to a first power-consuming component based on determining that it has an activity level below a first threshold and that power can be reduced to the first power-consuming component. Power provided to a second power-consuming component is reduced based on determining that it has an activity level below a second threshold and that power can be reduced to the second power-consuming component. Power reduction is forced in the compute node based on determining that power cannot be reduced in either of the first or second power-consuming component.
