METHODS AND APPARATUS FACILITATING ACCESS TO STORAGE AMONG MULTIPLE COMPUTERS

摘要

Multiple applications communicate tasks to a collective arbitrator. The arbitrator submits the tasks to a shared resource (work processor) for execution. For each segment of multiple segments of time, the arbitrator tracks consumption of time associated with execution of pending tasks submitted to the shared resource for execution on behalf of multiple applications. The arbitrator further controls subsequent submission of additional sets of one or more tasks to the shared resource for each of the multiple applications over successive segments of time depending on how much time it took the shared resource to perform the submitted tasks in one or more prior time segments. Tracking an amount of time that it takes the shared resource to execute submitted tasks and using such information to control future submission of tasks ensures that each of the task generating resources, over time, is provided fair use of the shared resource.

1. A method comprising:
partitioning time into contiguous time segments; submitting tasks from multiple resources to a shared resource for execution; within each time segment of the contiguous time segments, tracking time associated with execution of the tasks submitted to the shared resource for execution; and controlling subsequent submission of additional tasks to the shared resource for each of the multiple resources depending on the tracked time associated with execution of the submitted tasks.
