Abstract: Communication methods, systems, servers, and client devices in a user-interactive system are provided herein. In an exemplary method, a communication interface can be started via a first user-interactive client by a first user to communicate with one or more communication tools via a communication backend server. The first user-interactive client can obtain and display a plurality of second user IDs of second users. The first user-interactive client can receive one or more second user IDs selected by the first user to add to a communication group. The first user-interactive client can send to the communication backend server a message for joining the communication group containing the one or more second user IDs. After receiving an accepting message from the communication backend server, during a user-interactive operation, the first user-interactive client can communicate with a second client corresponding to a user ID contained in the accepting message.

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.
