Enhanced Backfill Computing

We are motivated to study (and eventually deliver) a cloud facility that has its "back door" open for incorporating voluntary computing resources, and such implemented cloud infrastructures have the potential to harmoniously serve both on-demand and non on-demand requests/jobs at possibly the lowest cost because of involvement of the low or no cost of using voluntary computing resources. This short paper presents our idea of enhancing the "backfill computing" model originally proposed by Marshall, et al. by incorporating voluntary computing resources into the resource pools of clouds, and summarizes the simulation results we had recently obtained.
