NIST SP2 Primer: Message Passing With PVM(e) Getting started with PVM programming. With some exceptions (noted in section on differences between PVM and PVMe), PVM and PVMe are source code compatible. http://math.nist.gov/~KRemington/Primer/mp-pvme.html
Extractions: PVMe is the IBM proprietary version of the widely used PVM message passing library from Oak Ridge National Laboratory. Its compatibility with the public domain PVM package generally lags one release behind. (For example, the current release of PVMe is compatible with PVM 3.2.6) We will assume that the reader has a basic understanding of the concept of message passing communication of data on distributed memory parallel architectures. PVM(e) is described here primarily by example, but for the interested reader, extensive PVM documentation is available from the PVM authors at PVM on Netlib and from the online documentation available on danube Before executing a PVM(e) message passing program, a ``Virtual Machine" (VM) must be initiated by the user. This is done by invoking what is known as the PVM(e) daemon, a process which sets up and maintains the information needed for PVM(e) processes to communicate with one another. In general, the user can ``customize" the VM by specifying which hosts it should include, the working directory for PVM processes on each host, the path to search for executables on each host, and so on. PVMe behaves slightly differently than PVM, since nodes are controlled through a Resource Manager. Rather than specifying particular nodes for the virtual machine, the user requests a certain number of nodes, and the Resource Manager reserves these nodes for that one particular user. This is to allow the user dedicated access to the High Performance Switch for the duration of their PVMe job.

Computer Terminology 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 http://www.netlib.org/benchmark/top500/reports/report94/benrep3/node4.html
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.
Function Decomposition A NAME=384 /A A diagram providing an overview of this example is shown in Figure (and will also be used in a later chapter dealing with graphical PVM programming). http://www.netlib.org/pvm3/book/node33.html
Extractions: Next: Porting Existing Applications Up: Workload Allocation Previous: Data Decomposition Parallelism in distributed-memory environments such as PVM may also be achieved by partitioning the overall workload in terms of different operations. The most obvious example of this form of decomposition is with respect to the three stages of typical program execution, namely, input, processing, and result output. In function decomposition, such an application may consist of three separate and distinct programs, each one dedicated to one of the three phases. Parallelism is obtained by concurrently executing the three programs and by establishing a "pipeline" (continuous or quantized) between them. Note, however, that in such a scenario, data parallelism may also exist within each phase. An example is shown in Figure , where distinct functions are realized as PVM components, with multiple instances within each component implementing portions of different data partitioned algorithms. Although the concept of function decomposition is illustrated by the trivial example above, the term is generally used to signify partitioning and workload allocation by function

The JPVM Home Page 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 http://www.cs.virginia.edu/~ajf2j/jpvm.html
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.
