Extractions: The Java Parallel Virtual Machine NOTE: If you are currently using JPVM, please download the latest version below (v0.2.1, released Feb.2, 1999). It contains an important bug fix to pvm_recv. JPVM is a PVM-like library of object classes implemented in and for use with the Java Programming language. PVM is a popular message passing interface used in numerous heterogeneous hardware environments ranging from distributed memory parallel machines to networks of workstations. Java is the popular object oriented programming language from Sun Microsystems that has become a hot-spot of development on the Web. JPVM, thus, is the combination of both - ease of programming inherited from Java, high performance through parallelism inherited from PVM. The reasons against are obvious - Java programs suffer from poor performance, running more than 10 times slower than C and Fortran counterparts in a number of tests I ran on simple numerical kernels. Why then would anyone want to do parallel programming in Java? The answer for me lies in a combination of issues including the difficulty of programming - parallel programming in particular, the increasing gap between CPU and communications performance, and the increasing availability of idle workstations. Developing PVM programs is typically not an easy undertaking for non-toy problems. The available language bindings for PVM (i.e., Fortran, C, and even C++) don't make matters any easier. Java has been found to be easy to learn and scalable to complex programming problems, and thus might help avoid some of the incidental complexity in PVM programming, and allow the programmer to concentrate on the inherent complexity - there's enough of that to go around.

Monday, Wednesday, Friday, 3:003:55. Room Lansing 300 (or in a lab). It is hardly necessary to explain the importance of computer networking. It's everywhere. Computer networks are very complex systems, with many levels of organization. It is certainly not possible to learn everything in one term. (Probably not in one lifetime, especially since things seem to change as fast as anyone can learn them.) The key to dealing with this complexity is to learn the basic ideas and fundamental theory of computer networking. I hope that the course will make that possible, while at the same time covering a lot of practical material. The main textbook for this course is Computer Networking: A Top-Down Approach Featuring the Internet, first edition, by James F. Kurose and Keith W. Ross. We will cover some material from each chapter in this book, while skipping some sections along the way. This book comes with access to a Web site, but I will probably not assign any specific readings from the Web site. The other major source of material will be the on-line user's guide for the Parallel Virtual Machine (PVM). PVM is a system used to write distributed programs. A distributed program is one that runs in pieces on a number of networked computers. We will cover PVM during the last two weeks of the term. There will be additional readings from handouts and on-line sources.

The absence of a general reference language for programming with this kind of architecture, has been the cause of the overabundance of distributed language proposals in the last fifteen years. Many of these proposals have had a wide distribution, such as PVM , but they don t allow the verification of the total correctness of programs. Others, even though carried out by important scientists, e.g. Joyce [6] haven t achieved the necessary diffusion to be implemented in concrete architectures.

Integration Of PVM Programs Into AVS Environment

Extractions: Next: Limitations in the Up: A Dataflow-Based Integration Previous: A General Parallel This section briefly describes how fine-grained parallel modules in a portable message-passing system such as PVM can be naturally incorporated into the coarse-grained dataflow modules in AVS. Background information about the Parallel Virtual Machine (PVM) can be found in Appendix B.2. By integrating PVM software into the AVS framework, the resulting system offers an equally sophisticated networking and visualization functionality with integrated networking and visualization programming interfaces. There can be two basic approaches to incorporating PVM programs into an AVS framework. They are based on the ways in which an AVS kernel interacts with PVM daemons: Our first approach embeds a PVM programming model at a lower level into AVS dataflow communications at the top inter-module level. As shown in Figure , there is a parallelism hierarchy in the system at two distinct levels: dataflow parallelism occurs among AVS visualization modules and between an AVS module and a remote PVM (host) computation module, and a general message-passing paradigm is used by the PVM node tasks. A PVM node task is spawned from the AVS/PVM host module when the module is registered in the Network Editor. The AVS kernel communicates with only one PVM host daemon through AVS input/output ports. All the AVS programming features (such as transparent networking, modular process management, and event-driven dataflow) remain intact, as well as the PVM concurrent programming paradigm. We use this approach in our case study, discussed in Appendix B.4.

Extractions: A. Reinefeld V. Schnecke Analogous to the shift from assembler language programming to the third-generation languages in the early years of computer science, we are currently witnessing a paradigm change towards the use of portable programming models in parallel high-performance computing. Like before, the use of a high-level programming environment must be paid for by a reduced system performance. But how much does portability cost in practice? Is it worth paying that price? What effect has the choice of the programming model on the algorithm architecture? In this paper, we attempt to answer these questions by comparing two applications from the domain of combinatorial optimization that have been implemented with the Parix and PVM programming models. Performance benchmarks have been run on three different systems: a massively parallel transputer system with relatively slow T805-processors, a moderately parallel Parsytec GC/PowerPlus system with powerful 80 MFLOPS processors, and a UNIX workstation cluster connected by a 10Mbps LAN. While the Parix implementations clearly turned out to be fastest, PVM gives portability at the cost of a small, acceptable loss in performance.

Extractions: PVM (Parallel Virtual Machine) is a software package that permits a heterogeneous collection of Unix computers hooked together by a network to be used as a single large parallel computer. Thus large computational problems can be solved more cost effectively by using the aggregate power and memory of many computers. The software is very portable. The source, which is available free thru netlib, has been compiled on everything from laptops to CRAYs. PVM enables users to exploit their existing computer hardware to solve much larger problems at minimal additional cost. Hundreds of sites around the world are using PVM to solve important scientific, industrial, and medical problems in addition to PVM's use as an educational tool to teach parallel programming. With thousands of users, PVM has become the de facto standard for distributed computing world-wide. PVM port to Windows.

Extractions: Next: How to get Up: Introduction Previous: Programming Models Nevertheless, most of our benchmarks are written to the distributed-memory MIMD programming model, with so-called scalable distributed-memory hardware in mind. The hardware of such computers consists of a large number of "nodes" connected by a communication network (typically with a mesh or hypercube topology), across which messages pass between the nodes. Each node typically contains one or more microprocessors for performing arithmetic (perhaps some with vector processing capabilities), communication chips that are used to interface with the network, and local memory. For this reason, the computational parts of the computer are commonly referred to as either "nodes" or "processors", and the computer is scaled up in size by increasing their number. Both names are acceptable, but "nodes" is perhaps preferable for use in descriptions of the hardware, because we can then say that one node may contain several processors. The F77+PVM programming model that we are using is, however, much simpler, in that the node is the smallest element of the computer that can be programmed, and it is always used as if it contained a single processor, because it runs a single F77 program. If the hardware actually uses several processors to run the single program faster, this should be beneficial to the benchmark result, but it is hidden from the programmer. Thus from the programmer's view, there is no useful distinction between node and processor, and in this document we have tried to use the term "processor" consistently to mean the "logical processor" of the F77+PVM programming model, whether or not it may be implemented by one or several physical processors.
