System and method of performing a pre-reservation analysis to yield an improved fit of workload with the compute environment
A system and method are disclosed for receiving a request for resources in a compute environment to process workload, the request including a specification of a quality of fit. The system generates a substantial maximum potential quality of fit based on compute environment with an assumption of no competing workload to yield an analysis. The system evaluates a first resource allocation and a second resource allocation against the analysis to yield the first fit in a respective second fit. The system selects one of the first resource allocation and the second resource allocation based on a comparison of the first fit to the second fit as well as a cost associated with any delays.
