Compute-intensive simulations typically charge substantial workloads on an online simulation platform backed by limited computing clusters and storage resources. Some (or most) of the simulations initiated by users may accompany input parameters/files that have been already provided by other (or same) users in the past. Unfortunately, these duplicate simulations may aggravate the performance of the platform by drastic consumption of the limited resources shared by a number of users on the platform. To minimize or avoid conducting repeated simulations, we present a novel system, called SUPERMAN (SimUlation ProvEnance Recycling MANager) that can record simulation provenances and recycle the results of past simulations. This system presents a great opportunity to not only reutilize existing results but also perform various analytics helpful for those who are not familiar with the platform. The system also offers interoperability across other systems by collecting the provenances in a standardized format. In our simulated experiments we found that over half of past computing jobs could be answered without actual executions by our system.
