It still is for SuperServer. But on Linux, Classic Server was already
available in FB 1.0 and it can run on an SMP, since each connection to the
server creates its own process. With FB 1.5, you'll also have a
Classic Server that runs on Windows.

Through Firebird's configuration file(Linux and Windows).
