P2D2 - A Portable Parallel/Distributed Debugger

Abstract

P2D2 is a debugger for parallel and distributed computations with a common interface on a variety of machines. This interface includes process navigation components that scale to a large number of processes. The design incorporates a client-server model and protocol which dictates the interaction between a message-passing library and the debugger, thereby isolating non-portable debugger code from the user interface. The process abstractions used for debugging message-passing programs can be easily adapted to debug HPF programs at the source level. This allows the debugger to present information hidden in tool-generated code in a meaningful manner.
