Facility/370: Introduction
File No. S370-20 Order No. GC20-1800=9 IDl\n \/:u+ •• ".1 I\n"n"': ..... ft IDIVI V IIlUQI .Via"'lllIlv Facility/370: Systems Introduction Release 6 PLC 4 This publication introduces VM/370, and 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 a system control program (SCP) that tailors the resources and capabilities of a single System/370 computer to provide concurrent users their one unique (virtual) machine. 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 a Interactive Problem Control System (I PCS), which provides problem analysis and management faci I ities. The first section of the publication is an introduction; it describes what VM/370 can do. The second, third, fourth, and fifth sections describe the Control Program, Conversational Monitor System, Remote Spooling Communications Subsystem, and Interactive Problem Control System respectively. The appendixes include information about VM/370 publication-to-audience relationship and VM/370-related publications for CMS users. , This publication is a prerequisite for the VM/370 system library. --...- --- ---.-- ------- ------ --..- --------- -~-y- Page of GC20-1800-9 As Updated Aug 1, 1979 by TNL GN25-0U89 ~b Edition (Karch 1919) This edition (GC20-1800-~ together with Technical Newsletter GN25-0489. dated August 1, 1919, applies to Release 6 PLC 4 (Program Level Change) of IBM Virtual Machine Facility/310 and to all subsequent releases until otherwise indicated in new editions or Technical Newsletters. -

The commoditization of the (binary translation) that enabled the execution of privileged x86 platform and its rapidly growing hardware capabilities have (OS) instructions from virtual machines on x86 systems [16]. led to recent exponential growth in the use of virtualization both Another notable effort was the Xen project, which in 2003 used in the enterprise and high performance computing (HPC). The a jump table for choosing bare metal execution or virtual startup time of a virtualized environment is a key performance machine execution of privileged (OS) instructions [17]. Such metric for high performance computing in which the runtime of projects prompted Intel and AMD to add the VT-x [19] and any individual task is typically much shorter than the lifetime of AMD-V [18] virtualization extensions to the x86 and x86-64 a virtualized service in an enterprise context. In this paper, a instruction sets in 2006, further pushing the performance and methodology for accurately measuring the startup performance adoption of virtual machines. on an HPC system is described. The startup performance overhead of three of the most mature, widely deployed cloud Virtual machines have seen use in a variety of applications, management frameworks (OpenStack, OpenNebula, and but with the move to highly capable multicore CPUs, gigabit Eucalyptus) is measured to determine their suitability for Ethernet network cards, and VM-aware x86/x86-64 operating workloads typically seen in an HPC environment. -

It’s only job is to emulate hardware and manage resources. • Does not provide file editing or writing capabilities. It can read CMS files for use with system configuration. • Cannot compile, assemble or execute programs. • CMS started out as an operating system during the early days of mainframes. • Became popular as a “guest” on CP to provide user/application functions. -
