  • Publication number: 20190012197
    Abstract: In a data processing system running at least one application on a hardware platform that includes at least one processor and a plurality of coprocessors, at least one kernel dispatched by an application is intercepted by an intermediate software layer running logically between the application and the system software. Compute functions are determined within kernel(s), and data dependencies are determined among the compute functions. The compute functions are dispatched to selected ones of the coprocessors based at least in part on the determined data dependencies and kernel results are returned to the application that dispatched the respective kernel.

  • Publication number: 20200201648
    Abstract: Execution of multiple execution streams is scheduled on a plurality of coprocessors. A software layer located logically between applications and the coprocessors determines dependencies within the execution streams, each said dependency being a condition in one of the execution streams that must be satisfied in order for execution of at least one other of the execution streams to proceed on corresponding ones of the coprocessors. The dependencies are then represented in a data structure and an optimized execution schedule is determined for the execution streams according to the dependencies. Simultaneous execution of a plurality of the execution streams is then dynamically reordered according to the optimized execution schedule.

  • Publication number: 20170293510
    Abstract: An interface software layer is interposed between at least one application and a plurality of coprocessors. A data and command stream issued by the application(s) to an API of an intended one of the coprocessors is intercepted by the layer, which also acquires and stores the execution state information for the intended coprocessor at a coprocessor synchronization boundary. At least a portion of the intercepted data and command stream data is stored in a replay log associated with the intended coprocessor. The replay log associated with the intended coprocessor is then read out, along with the stored execution state information, and is submitted to and serviced by at least one different one of the coprocessors other than the intended coprocessor.

  • Publication number: 20190114254
    Abstract: At least one application runs on a hardware platform that includes a plurality of coprocessors, each of which has a respective internal memory space. An intermediate software layer (MVL) is transparent to the application and intercepts calls for coprocessor use. If the data corresponding to an application's call, or separate calls from different entities (including different applications) to the same coprocessor, to the API of a target coprocessor, cannot be stored within the available internal memory space of the target coprocessor, but comprises data subsets that individually can, the MVL intercepts the call response to the application/entities and indicates that the target coprocessor can handle the request. The MVL then transfers the data subsets to the target coprocessor as needed by the corresponding kernel(s) and swaps out each data subset to the internal memory of another coprocessor to make room for subsequently needed data subsets.
