Abstract:

A parallel debugger is vital to improving the development efficiency of parallel programs. Based on the analysis of the function, interface and implem  entation issues of several mainstream industrial level parallel debuggers, we explore a general approach to designing a parallel debugger and propose a scalable parallel debugger model which is modularized and easy-to-integrate, and finally discuss the communications structure and message aggregation me chanism that can help improve the debug efficiency.

Key words: （parallel debugging, scalable, dynamic group communication, message aggregation）
