US Patent 8645745 Distributed job scheduling in a multi-nodal environment

Techniques are described for decentralizing a job scheduler in a distributed system environment. Embodiments of the invention may generally include receiving a job to be performed by a multi-nodal system which includes a cluster of nodes. Instead of a centralized job scheduler assigning the job to a node or nodes, each node has a job scheduler which scans a shared-file system to determine what job to execute on the node. In a job requiring multiple nodes, one of the nodes that joined the multi-nodal job becomes the primary node which then assigns and monitors the job's execution on the multiple nodes.
