Facilitating scheduling of jobs by decoupling job scheduling algorithm from recorded resource usage and allowing independent manipulation of recorded resource usage space

A method, system and program product are provided for facilitating scheduling of computer jobs of a computing environment having a plurality of resources. The method includes decoupling a job scheduling algorithm from responsibility for maintaining data structures for tracking recorded usage of the plurality of resources by computer jobs. The decoupling includes (i) providing resource space data structures separate from the job scheduling algorithm for recording usage of the plurality of resources by computer jobs; and (ii) providing operators for facilitating manipulation of values within the resource space data structures by the job scheduling algorithm and by one or more functions external to and independent of the job scheduling algorithm.
