Abstract: In an example, a management node includes a version rollback module to receive a request to upgrade a distributed computing system. Further, the version rollback module may upgrade the distributed computing system including a first service and a second service to a second version while retaining the first version of the first service and the second service. Upon upgrading the distributed computing system, the version rollback module may detect an issue associated with the second version of the first service. Upon detecting the issue, the version rollback module may perform a rollback operation to roll back the first service to the first version while retaining second version of the second service.

Abstract: A method includes determining, through test instructions executing on a processor of a data processing device, utilization of a graphics engine of the processor by an application executing thereon based on initiation thereof through a driver associated with the processor and/or an operating system executing on the data processing device, and detecting, through the test instructions, an idle state of one or more non-graphics engine(s) of the processor. The method also includes transitioning, through the processor, a frame buffer associated therewith into a self-refresh mode of low power utilization thereof, and copying data related to the execution of the application to a memory of the data processing device. Further, the method includes clock-gating the one or more non-graphics engine(s) to reduce a power consumption of the data processing device, and enabling the graphics engine to utilize the copied data in the memory for continued execution of the application.

Abstract: A method includes abstracting, through a driver component, a Graphics Processing Unit (GPU) of a data processing device as a set of GPUs. The GPU is configured to be received in an expansion port on a motherboard of the data processing device. The method also includes enabling, through the abstraction, utilization of a more number of lanes on the expansion port and/or another expansion port on the motherboard of the data processing device than a capability of the GPU otherwise.
