Abstract: The disclosed embodiments relate to a system, a method and instructions embodied on a non-transitory computer-readable storage medium that facilitate executing an external command during query processing. While commencing execution of a query that streams data through a pipeline comprising consecutive commands that are chained together (including the external command), the system launches an external process that executes the external command. Next, as chunks of data are subsequently streamed through the pipeline during query processing, the system uses a transport protocol to communicate the chunks of data to and from the external process to facilitate executing the external command on the chunks of data, without terminating and re-launching the external process between chunks of data.

Abstract: An integrated circuit package includes a digital logic die disposed on a substrate; and an interposer die stacked vertically with the digital logic die on the substrate. The interposer die includes at least one vertical transistor configured to selectively provide electrical power to a portion of the digital logic die.

Abstract: Various embodiments of the present invention are directed to methods that enable a memory controller to choose a particular operation mode for virtual memory devices of a memory module based on dynamic program behavior. In one embodiment, a method for determining an operation mode for each virtual memory device of a memory module includes selecting a metric (1001) that provides a standard by which performance and/or energy efficiency of the memory module is optimized during execution of one or more applications on a multicore processor. For each virtual memory device (1005), the method also includes collecting usage information (1006) associated with the virtual memory device over a period of time, determining an operation mode (1007) for the virtual memory device based on the metric and usage information, and entering the virtual memory device into the operation mode (1103, 1105, 1107, 1108).

Abstract: Various embodiments of the present invention are directed a multi-core memory modules. In one embodiment, a memory module (500) includes at least one virtual memory device and a demultiplexer register (502) disposed between the at least one virtual memory device and a memory controller. The demultiplexer register receives a command identifying one of the at least one virtual memory devices from the memory controller and sends the command to the identified virtual memory device. In addition, the at least one virtual memory devices include at least one memory chip.
