Extractions: Abstract: Many scientific problems benefit from computationsthat are parallel at a coarse grain. Collections of looselycoupled, heterogeneous computers are increasingly being applied to these problems. While individual computers are designed to be relatively reliable, a collection of several autonomous machines necessarily has a greater rate of failure. As data networks improve, and larger multicomputers are being used, rates of failure will increase. PVM (Parallel Virtual Machine) [Sun90, GS92] is a... (Update)

Extractions: PVM stands for Parallel Virtual Machine and was developed to allow the integration of workstations in a heterogeneous computing environment. As as standard for message passing PVM was replaced by MPI . Since MPI has become the standard for message passing HLRS only provides basic support for PVM. We strongly recommend to migrate from PVM to MPI if you do not explicitely need support for dynamic process control on heterogeneous clusters of workstations.

Extractions: Our intention is to give you basic support to run your PVM application successfully on the machine. PVM for the T3E is part of MPT and handling is therefore similar to MPI. For all details please have a look at the Message Passing Toolkit: PVM Programmer's Manual To use PVM the environment variable USE_PROG_ENV has to be set to 1. Normally this is done in the .profile that is provided for every user. So if you change to your own .profile make sure to have set there. All other parameters are set in the user independent part. Usage of PVM on the T3E needs no special linking or include information. Just like with MPI the MPT automatically recognizes a PVM code and includes necessary files and links necessary libraries automatically. PVM supports two programming styles that require a different way of running the job: SPMD style: If your program is of that type just run it like a normal parallel programm using mpprun: e.g. mpprun -n 8 spmd

Extractions: pp. 1019-1036 Abstract. We describe FATCOP, a new parallel mixed integer program solver written in PVM. The implementation uses the Condor resource management system to provide a virtual machine composed of otherwise idle computers. The solver differs from previous parallel branch-and-bound codes by implementing a general purpose parallel mixed integer programming algorithm in an opportunistic multiple processor environment, as opposed to a conventional dedicated environment. It shows how to make effective use of resources as they become available while ensuring the program tolerates resource retreat. The solver performs well on test problems arising from real applications and is particularly useful for solving long running hard mixed integer programming problems. Key words. mixed integer programming, Condor, opportunistic environment, branch-and-bound, fault tolerance AMS Subject Classifications PII Retrieve PostScript document ( 35391.ps

Extractions: Next: Communication Tests: BSD Up: Performance Evaluation of Communication Previous: Parallel Computer: IBM The Parallel Virtual Machine (PVM) is a collection of public-domain system software routines that enables parallel processing on a network of heterogeneous computers as well as parallel computers [ ]. It is composed of two parts: a run time system (daemon) that resides on all of the computers participating and a set of user interface primitives that can be incorporated into a Fortran (or C) code. This includes primitives for process control, message passing, and synchronization between processes running on different machines. The version that was used for this work is PVM 3.3. PVM daemons communicate with one another through UDP sockets while a PVM task communicates with its daemon over a TCP connection. For PVM tasks to communicate with each others, there are two routing modes: normal routing and direct routing. Normal routing involves three steps: a TCP connection between a task and its daemon, a UDP connection between the two daemons, and another TCP connection between the other task and its daemon. Direct routing, on the other hand, establishes a direct TCP link between tasks. Sending a message is normally composed of three steps in PVM: buffer initialization, message packing into the buffer, and sending the message. Receiving a message normally involves two steps: receiving and unpacking. PVM also provides another mechanism for communication called pack send (psend) and pack receive (precv). Pack send combines the three send steps into one while pack receive combines the two receive steps into one.

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.

CS160 - Concurrent Programming And Parallel Systems
Knowing how to write distributed programs is particularly valuable. This yearthe package we will use for distributed programming is called pvm.
http://www.cs.ucr.edu/~brett/cs160.html

Extractions: Study of concurrent and parallel systems. Modular structure and design. Interprocess communication, synchronization, failures and persistence, concurrency control, atomic transactions, recovery, language support, distributed interprocess communication. Implementation issues. The course introduces the fundamental concepts behind concurrent systems which are used in: operating systems, networking, real time systems, databases and multimedia systems. Concurrent systems are systems that have activites that happen at the same time. Knowing how to write concurrent programs is increasingly important, whether these programs are stand-alone programs for a single machine system or used in distributed computing systems. Concurrent programs may be written to the POSIX interface standard or Java supports concurrent programs. In this course, we will focus on the POSIX pthreads implementation of these concepts for the programming work. What you learn here can be taken to the Java environment and directly applied. The goal here is to learn to write programs that operate concurrently, first learning how to create concurrent activies, to synchronize them, and to put the pieces together into larger programs effectively so that components of the program operate concurrently. You will learn about the key synchronization methods which are important for programs to be able to cooperate or compete against one another while sharing resources. After we learn the basics, we study programs for distributed systems.
