Abstract

The paper introduces the concept of collective breakpoints and macrosteps. Based on the collective breakpoints the macrostep-by-macrostep execution mode has been defined. After introducing the concept of the execution tree and meta-breakpoints the systematic debugging of message passing parallel programs is explained. The main features and distributed structure of DIWIDE, a macrostep debugger is described. The integration of DIWIDE into the GRADE and WINPAR parallel programming environments is outlined.
