The GRED Graphical Editor for the GRADE Parallel Program Development Environment

摘要

In this paper, we describe a graphical editor GRED as part of the integrated programming environment GRADE that is intended to support designing, debugging and performance tuning of messagepassing programs running on a heterogeneous network of computers. The GRED editor hides the cumbersome details of the underlying lowlevel message-passing system (which is currently the PVM system) by providing visual abstractions but allows the programmer to define local computations of the individual processes in C (or in Fortran in the future) independently from the visually supported process management and inter-process communication activities.
