http://www.netlib.org/hence/ HeNCE - Heterogeneous Network Computing Environment <author> <version>2.0 <abstract> HeNCE (Heterogeneous Network Computing Environment) is an X-window based software environment designed to assist scientists in developing parallel programs that run on a network of computers. HeNCE provides the programmer with a high level abstraction for specifying parallelism. HeNCE is based on a parallel programming paradigm where an application program can be described by a graph. HeNCE graphs are variants of directed acyclic graphs, or DAGS. Nodes of the graph represent subroutines and the arcs represent data dependencies. Individual nodes are executed under PVM. HeNCE is composed of integrated graphical tools for creating, compiling, executing, and analyzing HeNCE programs. HeNCE relies on the PVM system for process initialization and communication. The HeNCE programmer, however, will never explicityly write PVM code. During or after execution, HeNCE displays an event-ordered animation of application execution, enabling the visualization of relative computational speeds, processor utilization, and load imbalances. <description><url>http://www.netlib.org/hence/</url> <reference><url>http://www.netlib.org/hence/hence-2.0-doc-html/hence-2.0-doc.html</url> <contact>hence@cs.utk.edu <keywords>parallel programming environment <category>ppt-env <publication-date> <environment> <method> <application> <comments> </urc>
