SPN model-based performance evaluation of job scheduling plans for distributed rendering environment

Based on the workflow of jobs under DRE (distributed rendering environment), mathematical modeling and performance evaluation were used to investigate different job scheduling plans. Firstly, a SPN (Stochastic Petri Nets) model for job scheduling with different priorities was constructed. Furthermore, using methodologies of SPN model and queuing one, effect of rendering rate, job priority on average completion time was conducted with exemplification, which offers key quantity foundations for designing and choosing appropriate job scheduling algorithms.
