Task scheduling through an operating system agnostic system abstraction layer from a top of the rack switch in a hyper converged infrastructure

摘要

An operating system agnostic task scheduler executes on a top of the rack device. The task scheduler receives from each of multiple nodes an operating system agnostic description of the node's computational resource capability and availability. The task scheduler uses the received information to maintain a resource accounting for each node. Requests to execute tasks are received by the task scheduler from external sources. The task scheduler matches specific tasks to specific nodes, based on the resource accounting. In response to matching a given task to a specific one of the nodes, the scheduler assigns the task to the node, and the task executes thereon. The task scheduler updates the maintained accounting based on computational resources allocated to the task by the node to which it was assigned.
