53 METHOD AND SYSTEM FOR SIMULATING THE EXECUTION OF A COMPUTER PROGRAM Abstract of the Disclosure A simulation system to simulate the execution of a computer program. The computer program is developed for invoking operating system functions of a first operating system. Each operating system function performs a behavior in accordance with passed parameters. The simulation system generates a log during the execution of the computer program under control of the first operating system. The log includes an indication of each invocation of an operating system function by the computer program and an indication of each parameter passed to the operating system function by the computer program and the current time. The logged execution is then simulated by the simulation system on a second operating system. The simulation system invokes an operating system function of the second operating system to perform a behavior similar to the behavior performed by each logged invocation of the operating system function of the first operating system in accordance with the passed parameters. Comparison of the functionality, reliability, and performance of the two systems are thereby enabled.
