Aspects of the disclosure provide for mechanisms for scheduling computing tasks in a computer system. A method of the disclosure includes determining one or more attributes associated with a computing task, determining an ordered list of the attributes in view of priorities associated with the attributes, generating a first numerical representation of the attributes in view of the ordered list of the attributes, determining a second numerical representation of a priority of the computing task, and determining a third numerical representation of a total priority of the computing task in view of the first numerical representation and the second numerical representation.

Computing task scheduling in a computer system utilizing efficient attributed priority queues

A method of rendering an object model includes modifying, by a first thread executing on a computer system that is coupled to a display screen, a current object model to generate a new object model that is stored at a first memory address. The method also includes storing, by the first thread, a copy of the new object model at a second memory address. The method further includes updating, by the first thread, a reference to identify the copy of the new object model. The method also includes rendering, by a second thread executing on the computer system, a renderable object model identified by the reference into a buffer that is converted into pixels on the display screen, the first thread being independent of the second thread.

Copy-on-write (COW) rendering of graphical object models

Aspects of the disclosure provide for mechanisms for scheduling computing tasks in a computer system. A method of the disclosure includes maintaining a priority queue comprising a plurality of computing tasks sorted in view of a plurality of numerical representations of priorities associated with the plurality of computing tasks; determining an attribute mask for a processing unit of a computer system, the attribute mask comprising a numerical representation of at least one attribute of the processing unit; and identifying, in view of the attribute mask, a computing task in the priority queue of the sorted computing tasks for processing by the processing unit of the computer system.
