Abstract: A non-transitory computer-readable storage medium may comprise a set of instructions for creating a subsystem process independent from a main system process for data computation. The set of instructions may direct at least one processor to perform acts of: in a main system process, receiving a user input; in the main system process, sending the user input to a subsystem process, the subsystem process is independent from and in parallel with the main system process; in the main system process, generating a first computation result according to the user input; in the subsystem process, generating a second computation result in parallel with the main system process according to the user input; in the main system process, receiving the second computation result from the subsystem process; and in the main system process, combining the first computation result and the second computation result.
