INTRODUCTION 1
NOS provides four types of job processing.
Local batch processing
The user enters jobs at the .central site and the
system processes them using only the central site
peripheral equipment attached to the computer.
Remote batch processing
The user submits jobs from remotely located 200
User Terminals, 731-12/732-12/734 Remote Batch
Terminals, or CDC CYBER 18-05 Remote Batch
Terminals.
Deferred batch processing
The user submits jobs entered from an interactive
terminal to the batch ,queue for processing; their
output can be routed to user-specified peripheral
equipment or remote batch locations.
Interactive terminal processing
The user enters jobs from an interactive network
terminal or a time-sharing terminal.
SYSTEM CONFIGURATION
NOS supports the following equipment. The specific
configuration may' vary, but consists of elements of the
following equipment.
Peripheral processors (PPs)
10, 14, 17, and 20 PP configurations of CYBER
, 170 Series computers and CYBER 70 Models 71,
72, 73, and 74 computers; 7, 8, 9, 10, and 20 PP
configurations of 6000 Series computers.
Central exchange jump/monitor exchange jump
(CEJ/MEJ)
All of the CYBER 170 Series computers and
CYBER 70 Models 71, 72, 73, and 74 computers
are equipped with CEJ/MEJ. It is an option on the
6000 Series computers. This option improves job
performance and should be used if it is available.
Display console
Basic equipment for all CYBER 170 Series
computers includes a single screen display
console. Two single screen-consoles are available
optionally~ CYBER 70 Models 71, 72, 73, and 74
computers and 6000 Series computers use the 6612
dual screen display console.

Mass storage
A minimum of 60 million characters of mass
storage on any of the following devices.
Extended core storage (ECS)
844 Disk Storage Subsystem
885 Disk Storage Subsystem
A dedicated permanent file device is
recommended in addition to system mass storage.
Peripheral equipment
Any of several combinations of the following
peripheral equipment.
580 Line Printers
405 Card Reader
415 Card Punch
667, 669, 677, and 679 Magnetic Tape Units
6671 Multiplexers for communication with
200 User Terminals and 731-12/732-12/734
Remote Batch Terminals
6671 or 6676 Multiplexers for communication
with interactive terminals
255x Network Processing Unit
Distributive data path (DDP)
The DDP option enables PPs to read and write
onto ECS directly rather than use the CPU
coupler.
OPERATOR/SYSTEM COMMUNICATION
Both NOS and the programs running under NOS use the
display screen to bring information to your attention. You
can respond to or instruct the operating system by entering
information via the console keyboard.
Two NOS routines, DSD and DIS, provide the interface
between the console hardware and other system software.
They maintain a current display of system or job status and
process commands you type at the keyboard. DSD is the
system display routine; information pertaining to all jobs
appears on the screen. DIS is the job display routine; the
screen shows data from a single job only. DSD has control
of the console until you initiate DIS.
