摘要： A method, system and memory controller for implementing memory hierarchy placement decisions in a memory system including direct routing of arriving data into a main memory system and selective injection of the data or computed results into a processor cache in a computer system. A memory controller, or a processing element in a memory system, selectively drives placement of data into other levels of the memory hierarchy. The decision to inject into the hierarchy can be triggered by the arrival of data from an input output (IO) device, from computation, or from a directive of an in-memory processing element.

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： 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.

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： 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.
