This publication introduces VM/370, and defines the
minimum equipment configuration necessary to
execute it. It is intended for anyone who is-interested
in VM/370. However, the reader should have a basic
understanding of I BM data processing.
VM/370 (Virtual Machine Facility/370) is an operating
system that manages the resources of a single System/370
computer so that multiple computing systems (virtual
machines) appear to ex'ist. VM/370 consists of a Control
Program (CP), which manages the real computer, a
Conversational Monitor System (CMS), which is a
general-purpose conversational time-sharing system that
executes in a virtual machine, a Remote Spooling
Communications Subsystem (RSCS), which spools files
to and from geographically remote locations, and an
Interactive Problem Control System (IPCS), which is
a problem reporting process.
The first section of the publication is an introduction;
it describes what VM/370 can do. The second, third,
and fourth sections describe the Control Program,
Conversational Monitor System, and Remote Spooling
Communications Subsystem, respectively. The appendixes
include information about system requirements, supported
language processors and emulators, and VM/370-related
publications for CMS users.
This publication is a prerequisite for the VM/370 system
library.
