Implementation of DDARC: Software Architecture for Debugging Distributed Programs

Debugging and testing is a larger part of the effort spent in a software development cycle. Debugging a program is time consuming and is a continuous cycle of code modification and testing. The task of debugging depends on the environment, the language, the operating system: the problem: and more interestingly even the individual program. In this paper, we present a detailed implementation of software architecture for debugging distributed programs. The debugger based on the proposed architecture supports debugging based on a mechanism for controlling multiple processes, presenting the process states, grouping of processes for ease in controlling the distributed programs developed on PVM based computing paradigm.
