Distributed Array Query and Visualization for High Performance Fortran

Abstract

Translate Article

This paper describes the design and implementation of the Distributed Array Query and Visualization (DAQV) system for High Performance Fortran, a project sponsored by the Parallel Tools Consortium. DAQV's implementation utilizes the HPF language, compiler, and runtime system to address the general problem of providing high-level access to distributed data structures. DAQV supports a framework in which visualization and analysis clients connect to a distributed array server (i.e., the HPF application with DAQV control) for programlevel access to array values. Implementing key components of DAQV in HPF itself has led to a robust and portable solution.KeywordsRuntime SystemProgram InteractionReference ImplementationExternal ToolData ClientThese keywords were added by machine and not by the authors.
