	The PVM System (Site not responding. Last check: 2007-10-19)
		PVM (Parallel Virtual Machine) is a byproduct of an ongoing heterogeneous network computing research project involving the authors and their institutions.
		PVM is an integrated set of software tools and libraries that emulates a general-purpose, flexible, heterogeneous concurrent computing framework on interconnected computers of varied architecture.
		Process-based computation: The unit of parallelism in PVM is a task (often but not always a Unix process), an independent sequential thread of control that alternates between communication and computation.

	PVM
		PVM is a software system that enables a collection of heterogeneous computers to be used as a coherent and flexible concurrent computa- tional resource.
		PVM needs to have environment variables set when it starts a slave pvmd with "rsh host pvmd...", so they must be set in.cshrc.
		PVM automatically detects collisions when generating a key and picks a new key, so it should almost never need to be set explicitly.

	Parallel Virtual Machine (PVM) Version 3
		PVM (Parallel Virtual Machine) is a software system that enables a collection of heterogeneous computers to be used as a coherent and flexible concurrent computational resource.
		PVM is particularly effective for heterogeneous applications that exploit specific strengths of individual machines on a network.
		The PVM system has been used for applications such as molecular dynamics simulations, superconductivity studies, distributed fractal computations, matrix algorithms, and in the classroom as the basis for teaching concurrent computing.

	A performance comparison of MPICH and PVM over Ethernet and ATM networks
		Native PVM and MPICH ATM layer drivers should be developed before any parallel message passing applications are ported to these ATM networks, as the generic TCP layer drivers do not fully exploit the performance advantages of ATM.
		PVM (Parallel Virtual Machine [cite PVM]) and MPI (Message Passing Interface [cite MPI]) are two standards for message passing libraries for distributed computing.
		The PVM implementation I tested initializes the communication channels at virtual machine startup time, and so the benchmarks are not affected by this.

	gridengine: Tight PVM Integration in Grid Engine
		This means, that the necessary daemons (which build up the PVM), will neither be under control of SGE, nor that all files on the slave nodes (created by PVM for its internal management) will be correctly deleted in case of a job abort.
		The PVM (Parallel Virtual Machine) is a framework from the Oak Ridge National Laboratory (http://www.csm.ornl.gov/pvm/pvm_home.html) and provides an interface for parallel programs, which allows the MPMD (multiple program multiple data) paradigm.
		PVM uses internally a scheduler on it's own, to distribute the by pvm_spawn() initiated tasks to the nodes (unless you use the option to specify the target node directly in pvm_spawn() on your own [according to the SGE granted nodes/slots of course]).

	An Introduction to PVM Programming
		PVM is a message passing system that enables a network of Unix computers to be used as a single distributed memory parallel computer.

	NIST SP2 Primer: Message passing with PVM(e)
		This utility, called the PVM console, is started by entering the command ``pvm." A variety of query commands can then be entered at the console prompt to determine, for example, which hosts belong to the VM, which processes are running under PVM, etc. See the documentation PVM on Netlib for detailed information.
		In coding a message passing program in PVM, calls to communication routines from PVM are included in the same way one makes subroutine calls in Fortran, or function calls in C. A program which requires PVM communication must "enroll" itself in the PVM virtual machine before these calls are made.
		For PVM, in contrast, there is a main daemon on the parent node, and a sub-daemon on each node in the VM.

	3.3 PVM (Site not responding. Last check: 2007-10-19)
		PVM or parallel virtual machine is a freely available library for running processes on more than one processor on one or more machines.
		To do this PVM must be installed on all the machines ROCS will be distributed over.
		ROCS is built with the current PVM version 3.4.4, but should also work with PVM version 3.4.3.

	Lab 5 Bakery Algorithm and PVM First Step
		PVM supports a higher level of portability that is extended to interoperability between different languages, messages can be sent and received between C and Fortran programs for example.
		Another feature of PVM is that it allows the development of fault tolerant applications that can survive host or task failure and provide notification to the user in this event, which could be a critical issue for large applications or long-time running simulations.
		PVM provides also a dynamic resource management and process control functions, user can add or delete hosts at will, giving a flexible control over the amount of computational power being utilized, thus leading to more efficiency.

	Parallel Processing on Linux with PVM and MPI LG #65
		The PVM System allows you to consider a group of interconnected LINUX system to be viewed as a ``virtual'' computer having much higher computing capacity than the individual machines.
		However, by default, PVM considers that only the host that you are working on is to be included in the PVM machine, i.e.
		To run the PVM programs, you need to run the PVM daemon which manages the exchange of messages and that what we are doing here.

		Whether you are installing PVM yourself or it is already installed for you, you must set have ~/.cshrc set your environment and path correctly before using or installing PVM.
		You invoke the console by typing "pvm" at the Unix shell prompt, and exit it by issuing the console's quit command at the console prompt.
		When you are done with your various PVM runs, you can kill the daemons on all nodes by re-entering the console and issuing the halt command.

		The PVM daemon pvmd3 is a Unix process which oversees the operation of user processes within a PVM application and coordinates inter-machine PVM communications.
		The "master" PVM daemon is the first PVM daemon started and is responsible for starting all other PVM daemons in your parallel virtual machine.
		The most common problem in starting PVM daemons is probably due to daemons already running on the machine(s), or the existence of a /tmp/pvmd.uid file.
