Patent attributes
Methods, nontransitory computer readable media, and systems are disclosed for servicing a job queue. Each job has node resource requirements. Composite job memory and processor requirements is determined from these requirements. Nodes that satisfy these requirements are identified by obtaining, for each class of a plurality of node classes: an availability score, a number of processors, and a memory capability. A request for nodes of a class is made when a demand score for the class satisfies the class availability score. An acknowledgement and updated availability score is received upon request acceptance. A declination is received upon request rejection. The submitting and receiving is performing multiple times, if needed, until each class has been considered for a request or sufficient acknowledgements are received to satisfy the composite requirements of the jobs. Each node in the cluster draws jobs from the queue subject to the collective requirements of the drawn jobs.
