Software Product Description
PRODUCT NAME:

RSX-11D, Version 6.2, Real Time Operating System

DESCRIPTION:
RSX-11 D is an event driven, disk based, multiprogramming, real-time operating system for PDP-11
with the memory management option. It uses memory
management hardware to isolate all other areas of
memory from a currently running program and to allow a program to be loaded anywhere in memory
without modification. The system is process-structured and provides priority queued asynchronous 110,
a powerful file structure, flexibile scheduling, and 250
levels of software priority.
The system is designed for use in applications that
require disk storage of programs and data, rapid
loading of programs in response to interrupts, and/or
convenient scheduling of operations.
The basic program unit executing under RSX-11 D is
the task, which consists of a program module or a set
of program modules. Program modules are linked
together and to the operating system by an overlay
task builder and stored on disk in absolute image
form. Task execution can be invoked by other tasks
or by a terminal user. Tasks can be specified to: a)
execute in an indicated memory partition, b) execute
at a given priority, c) execute under an indicated User
Identification Code, or d) execute only if memory is
available. Tasks can be defined as checkpointable,
which allows them to 'be swapped out of memory
when space is required for execution of higher priority tasks. Optionally, they can be declared as multiuser. Multi-user tasks are shareable, allowing more
than one user to have access to the reentrant part of
the task in parallel by duplicating only the data dependent code in memory.
Multi-programming of tasks is provided in RSX-11 D
by assigning a software priority level (1-250) to each
task. It allows interruption of a lower priority task
when higher ones require the CPU resources. Event
flags are provided to allow the individual task to control its execution and to allow communication with
other tasks and the operating system.

Console operations for RSX-11 D are supported by
tasks called the Monitor Console Routines (MCR). A
standard system contains routines for system service
requests, utility functions, and the following operations:
• Log on and log off
• Enter and display current time and date
• Install or remove tasks
• Mount or dismount peripheral volumes
• Initialize peripheral volumes
• Run and schedule tasks
• Create directory on a volume
• Set system defaults
• List installed tasks
• List devices
• List memory partitions
• List common memory areas
• Assign a logical unit number (LUN) of an indicated
task to an indicated physical device-unit
• List LUN aSSignments for an indicated task'
• Save a system image (for next boot)
• Examine (and alter) memory locations
The RSX-11 D File System provides support of files on
disk volumes. Four levels of file protection (SYSTEM,
OWNER, GROUP and WORLD) are supported via four
levels of access (READ, WRITE, EXTEND and DELETE). Both sequential and random access are supported for block structured and fixed-length record
files. Variable-length record files can only be
processed sequentially. All types of files can be expanded dynamically.
Other functions supported by the system are:
• 11/70 Extended memory support to a system total
of 1920K words
• 11/70 Cache parity checking and error logging support

• Time-scheduled partition option
• ANSI multi-volume magnetic tape support for fixed
and variable length records
• I/O spooling to the disk for low speed peripherals
(printer, terminal, and card reader) with associated
queue entries and operator output control
• Job/task accounting of CPU usage, device
accesses, and disk storage
• Error logging for system disks, including an error
analysis task and error report generator
• Optional on-line diagnostic disk handler tasks
• RSX-11 S system generation
The program development and utility functions provided by the standard RSX-11D system are as follows:
• Peripheral Interchange Program, PIP
• File Transfer Utility, FILEX
• Disk Save/Compress Utifity, DSC
• File Compare Utility, CMP
• File Dump Utility, DMP
• File Verification Utility, VERIFY
• Source Language Program Editor, SLiPR
• Character Oriented Text Editor, EDIT
• Library Management Utility, LBR
• PDP-11 Macro Assembler, MACRO
• Task Builder Overlay Linker, TKB
• Single Stream Batch, BATCH
• On-line Volume Backup Utility, PRE
• System Generation Program, SGN1
• On-line Debugging Technique, ODT
• Task Image Patch Program, ZAP
• FORTRAN-IV IAS/RSX, FOR
Single-user System:
RSX-11D systems are distributed as bootable 48K
word systems where memory is partitioned as follows:
EXEC - Resident Kernel Executive
SCOM - Tables, Lists, Code, and Nodes
MCR - Partition for MCR and some MCR functions
GEN - General-purpose partition for user tasks and
libraries, e.g., SYSRES
This configuration is the minimum recommended for
a single-stream command system. Non-batch program development is possible with this configuration,
but it is not recommended because of limited symbol
capabilities for the assembler or compilers running in
this smaller environment.

Multi-user System:
A SSK-word memory configuration with at least two
million words of disk storage is recommended for
concurrent program development and application execution. This provides adequate space for FORTRAN
IV libraries, a background compilation of large
FORTRAN programs, and residency of several
handler tasks.
The distributed RSX-11D system requires an RKOSJ
cartridge. Thus, more than one RKOS drive may be
necessary to meet the disk storage requirements for
an application. RSX-11D provides facilities for multiuser program development, but it is not a general
time-sharing system.
MINIMUM HARDWARE REQUIRED:
One of the following Processor systems with bootstrap, KW11 clock, console terminal and at least 48K
words of memory:
• PDP-11/34

• PDP-11/4S, 11/S5 with Memory Management Unit

• PDP-11/70
• One of the following disk systems: Note: If RSX-11S
systems are to be generated, at least 14 Megabytes
must be available on a single disk drive.
1. RK11 Disk Cartridge Controller .(includes one
RKOSJ disk drive)
