A Beginner's Guide To PVM Parallel Virtual Machine
pvm is based on the messagepassing model of parallel programming. A SimpleExample. There are a few elements common to all pvm programs.
http://www.itec.uni-klu.ac.at/~harald/PVM/pvm_guide.html

Extractions: PVM (Parallel Virtual Machine) is a software environment for heterogeneous distributed computing. It allows a user to create and access a parallel computing system made from a collection of distributed processors, and treat the resulting system as a single virtual machine (hence the name, parallel virtual machine). The hardware in a user's virtual machine may be single processor workstations, vector machines or parallel supercomputers or any combination of those. The individual elements may all be of a single type (homogeneous) or all different (heterogeneous) or any mixture, as long as all machines used are connected through one or more networks. These networks may be as small as a LAN connecting machines in the same room, as large as the Internet connecting machines across the world or any combination. This ability to bring together diverse resources under a central control allows the PVM user to divide a problem into subtasks and assign each one to be executed on the processor architecture that is best suited for that subtask. PVM is based on the message-passing model of parallel programming. Messages are passed between tasks over the connecting networks.

Extractions: Next: Computer Terminology Up: Introduction Previous: Background and Objectives Computer benchmarks are computer programs that form standard tests of the performance of a computer and the software through which it is used. They are written to a particular programming model and implemented by specific software, which is the final arbiter as to what the programming model is. PARKBENCH has initially adopted two such models: Fortran77 + PVM: This is the classical distributed-memory MIMD model in which a number of separate logical processors execute asynchronously independent Fortran77 programs in their individual and separate memory space. The only communication and synchronisation between these programs is by sending messages containing data using the PVM (Parallel Virtual Machine [ ]) library of Fortran communication subroutines. High Performance Fortran (HPF): This is an extension of the classical SIMD model in which a single instruction stream in the Fortran90 language [ ] specifies operations that apply, notionally simultaneously, to vectors and higher-order arrays of data.

Extractions: "Linux Gazette... making Linux just a little more fun! This article aims to provide an introduction to PVM and MPI, two widely used software systems for implementing parallel message passing programs. They enable us to use a group of heterogeneous UNIX/LINUX computers connected by a network as a single machine for solving a large problem. Parallel processing is a form of computing in which a number of activities are carried out concurrently so that the effective time required to solve the problem is reduced. In the previous days, parallel processing was used for such thing as large scale simulations (e.g. molecular simulations, simulation of the explosion of an atomic bomb etc), solving large number crunching and data processing problems (e.g. compiling the census data) etc. However, as the cost of hardware is decreasing rapidly, parallel processing is being uses more and more in routine tasks. Multiple processor servers have been in existence for a long time. Parallel processing is also used in your own PC too. For example, a graphics processor working along with the main processor to render graphics on your monitor is also a form of parallel processing. However, apart from the hardware facilities for parallel processing, some software support too is required so that we can run the programs in parallel and coordinate their execution. Such a coordination is necessary due to the dependencies of the parallel programs on one other. This will become clearer when we work through an example. The most widely used method to achieve such coordination is

Extractions: Index "PVM (Parallel Virtual Machine) is a portable message-passing programming system, designed to link separate host machines to form a ``virtual machine'' which is a single, manageable computing resource." - from the PVM FAQ PVM programs delegate their message passing requirements to pvmd - the PVM daemon - a copy of which must be running on every machine in the parallel environment. On the HPC, this process has been integrated into Codine/SGE, in order to simplify the process of running PVM programs, and to ensure that the machine resources are evenly distributed. Once a PVM program has been compiled, it should be placed in job script in a similar manner to running simple jobs using the qsub command. An additional set of arguments is required to instruct Codine that a PVM parallel environment is required, and that a specific number of slots is requested. For example: qsub -pe pvm 4 The above would request four pvm slots on the HPC. A fuller description of the

Later chapters of this book describe how to write parallel PVM programs. In this section we will work with the example programs supplied with the PVM software. These example programs make useful templates on which to base your own PVM programs. The first step is to copy the example programs into your own area: % cp -r $PVM_ROOT/examples $HOME/pvm3/examples % cd $HOME/pvm3/examples The examples directory contains a Makefile.aimk and Readme file that describe how to build the examples. PVM supplies an architecture-independent make, aimk , that automatically determines PVM_ARCH and links any operating system specific libraries to your application. aimk was automatically added to your $PATH when you placed the cshrc.stub in your .cshrc file. Using aimk allows you to leave the source code and makefile unchanged as you compile across different architectures. The master/slave programming model is the most popular model used in distributed computing. (In the general parallel programming arena, the SPMD model is more popular.) To compile the master/slave C example, type

Extractions: January 16, 2001 PVM is particularly effective for heterogeneous applications that exploit specific strengths of individual machines on a network. As a loosely coupled concurrent supercomputer environment, PVM is a viable scientific computing platform. T he PVM system has been used for a applications such as molecular dynamics simulations, superconductivity studies, distributed fractal computations, matrix algorithms, and in the classroom as the basis for teaching concurrent computing. This is a brief guide on how to get started using PVM. It was written for PVM version 3.4.3 which is the version currently installed on the Sun machines in the CS undergrad kitchen lab. It assumes that someone has set up PVM to run on th e platform you are using. If this is not the case you will need to download and install a copy of PVM from the ORNL home page.

Condor-PVM Homepage
In Condor pvm, Condor acts as the resource manager for the pvm daemon. Whenever yourpvm program asks for nodes (machines), the request is remapped to Condor.
http://www.cs.wisc.edu/condor/pvm/

Extractions: PVM stands for Parallel Virtual Machines, and is a set of message passing privitives for use in C and C++. It also is a system of dynamic host management, where "nodes" in the virtual machine may come and go at any time. For more information on the PVM project, see their home page In Condor PVM, Condor acts as the resource manager for the PVM daemon. Whenever your PVM program asks for nodes (machines), the request is re-mapped to Condor. Condor then finds a machine in the Condor pool via the usual mechanisms, and adds it to the PVM virtual machine. If a machine needs to leave the pool, your PVM program is notified of that as well via the normal PVM mechanisms. There are several different parallel programming paradigms. One of the more common is the "master-worker" or "pool of tasks" arrangement. In a master-worker program model, one node acts as the controlling master for the parallel application and sends pieces work out to worker nodes. The worker node does some computation, and sends the result back to the master node. The master has a pool of work that needs to be done, and simply assigns the next piece of work out to the next worker that becomes available. Condor PVM is designed to run PVM applications which follow the master-worker paradigm. Condor runs the master application on the machine where the job was submitted and will not preempt it. Workers are pulled in from the Condor pool as they become available.
2.9 PVM Applications
Whenever a pvm program asks for nodes (machines), the request is forwardedto Condor. This job has a master pvm program called master.exe.
http://www.cs.wisc.edu/condor/manual/v6.6/2_9PVM_Applications.html

Extractions: 2.9 PVM Applications Applications that use PVM (Parallel Virtual Machine) may use Condor. PVM offers a set of message passing primitives for use in C and C++ language programs. The primitives, together with the PVM environment allow parallelism at the program level. Multiple processes may run on multiple machines, while communicating with each other. More information about PVM is available at http://www.epm.ornl.gov/pvm/ Condor-PVM provides a framework to run PVM applications in Condor's opportunistic environment. Where PVM needs dedicated machines to run PVM applications, Condor does not. Condor can be used to dynamically construct PVM virtual machines from a Condor pool of machines. In Condor-PVM, Condor acts as the resource manager for the PVM daemon. Whenever a PVM program asks for nodes (machines), the request is forwarded to Condor. Condor finds a machine in the Condor pool using usual mechanisms, and adds it to the virtual machine. If a machine needs to leave the pool, the PVM program is notified by normal PVM mechanisms. NOTE : Condor-PVM is an optional Condor module. It is not automatically installed with Condor. To check and see if it has been installed at your site, enter the command:

Extractions: PVM (Parallel Virtual Machine) The PVM software provides a unified framework within which parallel programs can be developed in an efficient and straightforward manner using existing hardware. PVM enables a collection of heterogeneous computer systems to be viewed as a single parallel virtual machine. PVM transparently handles all message routing, data conversion, and task scheduling across a network of homogeneous or heterogeneous computer architectures. The PVM computing model is simple yet very general, and accommodates a wide variety of application program structures. The programming interface is deliberately straightforward, thus permitting simple program structures to be implemented in an intuitive manner. The user writes his application as a collection of cooperating tasks. Tasks access PVM resources through a library of standard interface routines. These routines allow the initiation and termination of tasks across the network, as well as communication and synchronization between tasks. The PVM message-passing primitives are oriented towards heterogeneous operation, involving strongly typed constructs for buffering and transmission. Communication constructs include those for sending and receiving data structures as well as high-level primitives such as broadcast, barrier synchronization, and global sum. PVM tasks may possess arbitrary control and dependency structures. In other words, at any point in the execution of a concurrent application, any task in existence may start or stop other tasks or add or delete computers from the virtual machine. Any process may communicate and/or synchronize with any other. Any specific control and dependency structure may be implemented under the PVM system by appropriate use of PVM constructs and host language control-flow statements.
