        Non-blocking call that checks whether the solver has received a response
        from the remote resource.

        Returns:
            Boolean: True if solver received a response.

        Examples:
            This example creates a solver using the local system's default
            D-Wave Cloud Client  configuration file, submits a simple QUBO
            problem to a remote D-Wave resource for 100 samples, and checks a
            couple of times whether sampling is completed.
