GRADE: A graphical programming environment for PVM applications

The PVM system { which is one of the most popular message-passing interface currently { represents a low-level tool that enables to write parallel programs but misses the high-level support which could make this work acceptable easy and eecient. To provide high-level graphical support for PVM based program development , a complex programming environment (GRADE) is being developed. GRADE provides tools to construct, execute, debug and visualise message-passing parallel programs. GRADE ooers the programmer the same graphical user interface during the whole development process. This paper deals with the graphical program editor and the post-mortem visualising tool in details.
