YH-SUPE (YinHe-Simulation Utilities for Parallel Environment) is an infrastructure for developing and executing the programs of parallel simulation. Parallel simulation based on the high performance computer is often applied to get the final results that acquired only after parallel simulation is executed for many times with different scenarios and parameters. If it is users’responsibility to

Instance-intensive workflow is an important and increasingly widely used commercial application. Online shopping with millions of transactions each day, which is still growing at a rapid rate, is just an example of the instance-intensive workflow applications. While traditional distributed computing, parallel computing and grid computing can hardly handle the fast growing instance-intensive workflow applications with
