consistently by the tasks themselves; that is, the superviser
provides only the support necessary to control and coordinate the
execution of the tasks.
InRSCS, a task is a single program or set of subprograms that can
run concurrently and autono.ously with other suchprograms and subprcgrams, and which uses control functions provided by the
Supervisor.
There are two of tasks: system service tasks and line driver
tasks. The system service tasks are those that provide the systemsUFport functions for the supervisor and for other tasks. The line
driver tasks are these that manage the transmission paths to remote
stations and that interact between the remote stations and the system
service tasks and the Supervisor. Each line driver task manages tbe
transmission of files to andfrom a single remote station.
Figures 12 and 13 inSection 2 show the communications paths tetween the supervisor, system service tasks, line driver tasks, remote
stations, andV8/310 virtual machines.
TheRSCS Supervisor
The Rses supervisor is composed of a set of service routines that
provide functions for the tasks that run under them. These service
routines may be called by any task. In general, they provide four kinds
of services:• Task management • I/O management • Interrupt handling • Virtual storage management
