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. -
Introducing Linux on IBM Z Systems IT Simplicity with an Enterprise Grade Linux Platform
Introducing Linux on IBM z Systems IT simplicity with an enterprise grade Linux platform Wilhelm Mild IBM Executive IT Architect for Mobile, z Systems and Linux © 2016 IBM Corporation IBM Germany What is Linux? . Linux is an operating system – Operating systems are tools which enable computers to function as multi-user, multitasking, and multiprocessing servers. – Linux is typically delivered in a Distribution with many useful tools and Open Source components. Linux is hardware agnostic by design – Linux runs on multiple hardware architectures which means Linux skills are platform independent. Linux is modular and built to coexist with other operating systems – Businesses are using Linux today. More and more businesses proceed with an evolutionary solution strategy based on Linux. 2 © 2016 IBM Corporation What is IBM z Systems ? . IBM z Systems is the family name used by IBM for its mainframe computers – The z Systems families were named for their availability – z stands for zero downtime. The systems are built with spare components capable of hot failovers to ensure continuous operations. IBM z Systems paradigm – The IBM z Systems family maintains full backward compatibility. In effect, current systems are the direct, lineal descendants of System/360, built in 1964, and the System/370 from the 1970s. Many applications written for these systems can still run unmodified on the newest z Systems over five decades later. IBM z Systems variety of Operating Systems – There are different traditional Operating Systems that run on z Systems like z/OS, z/VSE or TPF. With z/VM IBM delivers a mature Hypervisor to virtualize the operating systems. -
Survey on Virtualization with Xen Hypervisor
International Journal of Engineering Research & Technology (IJERT) ISSN: 2278-0181 Vol. 1 Issue 8, October - 2012 Survey On Virtualization With Xen Hypervisor Mr.Tejas P.Bhatt*1, Asst.Prof.Pinal.J.Patel#2 * C.S.E. Department, Government College of Engineering, Gandhinagar Gujarat Technology University, Gujarat, India. # C.S.E. Department, Government College of Engineering, Gandhinagar Gujarat Technology University, Gujarat, India Abstract In the cloud computing, there is one virtual machine that need them. For this reason, cloud computing has also can created and put it out on the physical machine with been described as "on-demand computing." The Internet providing the ideas using the hypervisors. So the is utilized as a vehicle but it is not the cloud. Google, Amazon, eBay, etc utilize cloud technologies to provide virtualization technology has limit security capabilities in services via the Internet. The cloud technologies are an order to secure wide area environment such as the cloud. operating technology built on a vast number of computers While consolidating physical to virtual machines using that provide a service [1]. Google as a best example of Xen hypervisor, we want to be able to deploy and manage cloud computing. What happens when you type and virtual machines in the same way we manage and deploy search something on Google? Have you ever thought physical machines. For operators and support people about this? Does your PC go through all that information, there should be no difference between virtual and sorts it out for you and display all the relevant results? IJERTNo, it doesn’t. Otherwise, you would wait much longer physical installations Therefore, the development of a for a simple results page to display. -

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. -
