  • Publication number: 20240111588
    Abstract: Intelligent process management is provided. A start time is determined for an additional process to be run on a worker node within a duration of a sleep state of a task of a process already running on the worker node by adding a first defined buffer time to a determined start time of the sleep state of the task. A backfill time is determined for the additional process by subtracting a second defined buffer time from a determined end time of the sleep state of the task. A scheduling plan is generated for the additional process based on the start time and the backfill time corresponding to the additional process. The scheduling plan is executed to run the additional process on the worker node according to the start time and the backfill time corresponding to the additional process.

  • Patent number: 11930411
    Abstract: Disclosed herein a system, a method and a device for selecting between a primary link and a secondary link for AR/VR applications. A console can provide a VR/AR session to a user through a head wearable display. The console can determine that a first measurement of a primary link between the console and a head wearable display is less than a first threshold. The first measurement can include a quality metric of the primary link. The console can activate a secondary link between the console and the head wearable display. The console can determine whether a second measurement of the primary link between the console and the head wearable display is less than a second threshold. The console can transition when the second measurement is less than the second threshold, traffic on the primary link to the activated secondary link.

  • Patent number: 9159353
    Abstract: Fabrication methods for magnetic recording media that use a plasma polish are disclosed. For one exemplary method, a film of a magnetic recording medium is deposited, and a top surface of the film is polished utilizing a plasma formed by a noble gas to smoothen the top surface of the film. A subsequent layer is then deposited onto the polished top surface of the film. A top surface of the subsequent layer has a reduced roughness by being deposited on the polished top surface of the film.
