摘要： A computer detects a request by a process for access to a shadow control page, wherein the shadow control page allows the process access to one or more devices. The computer assigns the shadow control page and a key to the process associated with the request. The computer detects a request by the process via the assigned shadow control page for creation of a subset of devices from the one or more devices. The computer inputs information detailing an association between the subset of devices and the assigned key into a subset definition table, wherein the subset definition table includes one or more keys and one or more corresponding subsets.

摘要： According to one embodiment, a method for traffic prioritization in a memory device includes sending a memory access request including a priority value from a processing element in the memory device to a crossbar interconnect in the memory device. The memory access request is routed through the crossbar interconnect to a memory controller in the memory device associated with the memory access request. The memory access request is received at the memory controller. The priority value of the memory access request is compared to priority values of a plurality of memory access requests stored in a queue of the memory controller to determine a highest priority memory access request. A next memory access request is performed by the memory controller based on the highest priority memory access request.

摘要： 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.

摘要： According to one embodiment, a system is provided that includes at least one power gated component and two or more power switch transistors configured to provide one or more conductive paths between a common power supply rail, the at least one power gated component, and a ground. The two or more power switch transistors each include a source terminal, a drain terminal, and a gate terminal configured to control current flow between the source and drain terminals. The system also includes a rotating voltage control coupled to the gate terminals and configured to apply a sequence of control signals rotating between an on-state and an off-state to each of the gate terminals while the at least one power gated component is turned on. A switch activation ratio level is programmable to set a number of power switch transistors in the on-state relative to a total number of power switch transistors.

摘要： An aspect includes providing rollback support in an exposed-pipeline processing element. A method for providing rollback support in an exposed-pipeline processing element includes detecting, by rollback support logic, an error associated with execution of an instruction in the exposed-pipeline processing element. The rollback support logic determines whether the exposed-pipeline processing element supports replay of the instruction for a predetermined number of cycles. Based on determining that the exposed-pipeline processing element supports replay of the instruction, a rollback action is performed in the exposed-pipeline processing element to attempt recovery from the error.

摘要： Embodiments relate to sequential location accesses in an active memory device that includes memory and a processing element. An aspect includes a method for sequential location accesses that includes receiving from the memory a first group of data values associated with a queue entry at the processing element. A tag value associated with the queue entry and specifying a position from which to extract a first subset of the data values is read. The queue entry is populated with the first subset of the data values starting at the position specified by the tag value. The processing element determines whether a second subset of the data values in the first group of data values is associated with a subsequent queue entry, and populates a portion of the subsequent queue entry with the second subset of the data values.
