Abstract

Network computing seeks to utilize the aggregate resources of many networked computers to solve a single problem. In so doing it is often possible to obtain supercomputer performance from an inexpensive local area network. The drawback is that network computing is complicated and error prone when done by hand, especially if the computers have different operating systems and data formats and are thus heterogeneous. The heterogeneous network computing environment (HeNCE) is an integrated graphical environment for creating and running parallel programs over a heterogeneous collection of computers. It is built on a lower level package called parallel virtual machine (PVM). The HeNCE philosophy of parallel programming is to have the programmer graphically specify the parallelism of a computation and to automate, as much as possible, the tasks of writing, compiling, executing, debugging, and tracing the network computation. Key to HeNCE is a graphical language based on directed graphs that describe the parallelism and data dependencies of an application. Nodes in the graphs represent conventional Fortran or C subroutines and the arcs represent data and control flow. This article describes the present state of HeNCE, its capabilities, limitations, and areas of future research.

HeNCE: Graphical development tools for network-based concurrent computing

Conference Beguelin, A ; Dongarra, J ; Geist, A ; ...

HeNCE (Heterogeneous Network Computing Environment) is an X Window based graphical parallel programming environment that was created to assist scientists and engineers with the development of parallel programs. HeNCE provides a graphical interface for creating, compiling, executing, and debugging parallel programs, as well as configuring a distributed virtual computer (using PVM). HeNCE programs can be run on a single Unix workstation or over a network of heterogeneous machines. This paper describes the purpose and use of the HeNCE software.

Graphical development tools for network-based concurrent supercomputing

Conference Beguelin, A ; Dongarra, J ; Geist, A ; ...

This paper describes an X-window based software environment called HeNCE (Heterogeneous Network Computing Environment) designed to assist scientists in developing parallel programs that run on a network of computers. HeNCE is built on top of a software package called PVM which supports process management and communication between a network of heterogeneous computers. HeNCE is based on a parallel programming paradigm where an application program can be described by a graph. Nodes of the graph represent subroutines and the arcs represent data dependencies. HeNCE is composed of integrated graphical tools for creating compiling executing and analyzing HeNCE programs.

XPVM: A graphical console and monitor for PVM

Conference Kohl, J A

As technology continues to spawn new supercomputing platforms and more powerful workstation environments, it becomes increasingly important to integrate and apply these diverse collections of computers together to extract. the best performance possible. PVM (Parallel Virtual Machine) is gaining wide popularity as a means for realizing the computing power of these heterogeneous systems. PVM is a software package that permits a heterogeneous collection of serial, parallel and vector computers, hooked together by a network, to appear as one large distributed memory computer. One of the primary difficulties in designing applications for distributed computer systems is identifying precisely what is happeningmore »« less
