ABSTRACT:- In the autumn of 1969, we decided to try a new approach to the design of a virtual machine operating system. Until that time, most installations using Virtual Machine Monitors merely ran operating systems that already existed for €œstand-alon use. Few, if any, installations had attempted to design and create an operating system that took advantage of its running environment. The Virtual Machine Monitor we were using was a highly modified version of CP-67 which was designed to operate on an IBM S/360 Model ....etc

Seminar on The Virtual Machine



A virtual machine (VM) is a software implementation of a computing environment in which an operating system (OS) or program can be installed and run.
The virtual machine typically emulates a physical computing environment, but requests for CPU, memory, hard disk, network and other hardware resources are managed by a virtualization layer which translates these requests to the underlying physical hardware.

ABSTRACT
We present empirical evidence to demonstrate that there is little or no difference between the Java Virtual Machine and the .NET Common Language Runtime, as regards the compilation and execution of object-oriented programs. Then we give details of a case study that proves the superiority of the Common Language Runtime as a target for imperative programming language compilers (in particular GCC).

Abstract
The subjects of virtual machines and emulators have been treated as entirely separate. The purpose of this seminar is to show they have much in common. Only the usual implementations have many shared characteristics, but this extends to the theoretical concepts on which they are based; the concepts of memory mapping and I/O operation simulation are discussed to emphasize this. It also discusses structural issues, and points out why the question of instruction set is becoming less valid as a point of distinction between the concepts, ....etc

Parallel Virtual Machine (PVM) is software system that allows a homogenous (same type) or heterogeneous (different types) networks of computers to be used as a single computational resource . The individual computers may be interconnected by a variety of networks such as Ethernet or FDDI. PVM is used to build and manage the virtual parallel machine and provide the necessary message passing communication. By sending and receiving messages, multiple tasks can be used co-operatively to solve problems in parallel. Under PVM a network of workstatio ....etc
