1. A computer system with simulation computational resources including a plurality of computers with a processor and a memory and configured to execute a simulation, comprising: a dynamic computational resource distribution unit which is connected to a terminal via a network, receives a request to create a simulation task from the terminal, creates a simulation configuration included in the simulation task based on the request from the terminal and issues a simulation included in the simulation configuration to the simulation computational resources; a storage unit for storing the request to create the simulation task received from the terminal; and a history monitoring unit for collecting an operation history for the simulation task received from the terminal and loads of the simulation computational resources required to execute the simulation task for each user of the terminal; wherein: the simulation computational resources includes a plurality of types of simulators in advance; and the dynamic computational resource distribution unit records elements of simulations executed by the simulation computational resources, applies recorded elements of past simulations to the received simulation task and allocates the simulation computational resources for executing simulations to which the elements are applied based on the loads of the simulation computational resources collected by the history monitoring unit.
