  • Publication number: 20250147802
    Abstract: Techniques and systems disclosed herein may relate to a server processing work requests of a work requester. For example, the work requester may generate a plurality of work requests comprising functions of an application to be executed by a dependency-aware (DA) server, determine processing dependencies associated with the work requests, communicate, to the DA server, the processing dependencies, and enqueue the work requests on a dependent queue and a conditioned dependent queue based on processing dependencies associated with the DA server. The DA server may then select one of the work requests from the dependent queue or the conditioned dependent queue for processing and processing the selected work request.

  • Publication number: 20250140642
    Abstract: A thermoelectric cooler (TEC) is positioned to move heat away from a hot spot on a semiconductor chip and toward a dielectric substrate. This approach to thermal management is particularly effective when used in conjunction with a buried rail and back side power delivery. The TEC may be in a layer that contains solder connections be between two device layers an IC package. Alternatively, the TEC may be in a metal interconnect structure over the semiconductor substrate such as in a passivation stack at the top of the metal interconnect structure. TECs at either of these locations may be formed by wafer-level processing.

  • Patent number: 12235693
    Abstract: A drive tray assembly is disclosed for placing drives (e.g., hard disk drives) in a computer chassis in a rotated orientation and without the need for additional tools. A tray base holding a drive can be slid into a receiving space of the chassis in a longitudinal direction. An installation lever rotatably attached to the tray base includes a shaft that engages a corresponding receiving slot of the receiving space. After the tray base is inserted, rotation of the installation lever to a closed position causes the tray base, and thus the drive, to move in a direction perpendicular to the longitudinal direction. A release lever rotatably attached to the tray base can secure the installation lever in the closed position until the release lever is rotated, freeing the installation lever to move to the open position in which the drive tray may be removed from the chassis.

  • Patent number: 12205635
    Abstract: A memory module with improved timing adaptivity of sensing amplification, comprises at least one sensing amplifier, a tracking word line, a tracking bit line and a pulse-width controller. The tracking word line comprises a front node and an end node. Each said sensing amplifier is enabled/disabled when an enabling signal is activated/deactivated. The pulse-width controller is coupled to the tracking bit line, the front node and the end node. When a voltage of the tracking bit line changes to a predetermined voltage, the pulse-width controller activates the enabling signal, and causes a voltage of the front node to change. When the voltage of the front node changes, the tracking word line causes a voltage of the end node to change after a first delay time. When the voltage of the end node changes, the pulse-width controller deactivates the enabling signal after a second delay time.

  • Publication number: 20230385103
    Abstract: In a method an Intelligent Data Conversion (IDC) engine of a dataflow system detects a stage transition of a dataflow application executing on the dataflow system. In response, the IDC engine determines that data among stage data of the application has a first Stage Data Format (SDF). The IDC engine determines that a first processing unit of the dataflow system can process data having a second SDF and determines a data conversion to convert data among the stage data to have the second SDF. The IDC engine also determines a second processing unit, of the dataflow system to perform the data conversion and dispatches the second processing unit to perform the data conversion. The dataflow computing system can include a runtime processor and the IDC engine can interact with the runtime processor to detect the stage transition and/or dispatch the first processing unit.
