Debugging in Parallel or Sequential: An Empirical Study

Yulei Pang, Xiaozhen Xue, Akbar Siami Namin
2015 Journal of Software  
A program with multiple faults can be debugged in parallel where each sub-process specifically targets localizing one of the bugs.  ...  The need for speeding up the debugging process is even more immense when the program under test contains multiple faults.  ...  effectiveness of the two strategies, the result in Section 6.1 indicates that overall parallel debugging outperforms sequential debugging, whereas, the different is statistically insignificant.  ...

Debugging parallel programs using fork handlers

Javier Alcázar Zapién
2015 Proceedings of the Sixth International Workshop on Programming Models and Applications for Multicores and Manycores - PMAM '15  
Debugging programs composed of multiple processes turns out to be more complicated than debugging multi-threaded programs composed of a single process.  ...  In the main implementation of Python, Ruby and other platforms, the only way to achieve real parallelism in multicore computers is using multiple processes rather than multiple threads.  ...  the reasons that make parallel programs more error prone.  ...

Debugging in Parallel

James A. Jones, James F. Bowring, Mary Jean Harrold
2007 Proceedings of the 2007 international symposium on Software testing and analysis - ISSTA '07  
Our approach consists of a technique that enables more effective debugging in the presence of multiple faults and a methodology that enables multiple developers to simultaneously debug multiple faults.  ...  The paper also presents an empirical study that demonstrates that our parallel-debugging technique and methodology can yield a dramatic decrease in total debugging time compared to a one-fault-ata-time  ...  The novel component of this parallel-debugging process, Cluster, is shown in more detail in Figure 9 . We have developed two techniques to Cluster failed test cases.  ...

Fitting a workflow model to captured development data

Min Zhang, Lorin Hochstein
2009 2009 3rd International Symposium on Empirical Software Engineering and Measurement  
In this paper, we introduce a semi-automated process called software engineering workflow analysis (SEWA) for developing heuristics that analyze captured data to identify where programmers spend their  ...  To evaluate our process, we ran two case studies in the domain of high-performance computing to generate programmer workflow models for small problems, cross-checking our results against direct observations  ...  For debugging, we could have chosen to distinguish between serial debugging and parallel debugging, which would make the workflow model more precise but more complex.  ...

An Optimized Approach of Fault Distribution for Debugging in Parallel

Maneesha Srivasatav, Yogesh Singh, Durg Singh Chauhan
2010 Journal of Information Processing Systems  
This helps in the efficient merging of two or more slices for distribution among debuggers so that debugging can be performed in parallel.  ...  In this paper we propose a new technique called Faulty Slice Distribution (FSD) to make parallel debugging more efficient by measuring the time and labor associated with a slice.  ...  This technique has been termed 'parallel debugging'. Debugging in parallel reduces the time required to debug multiple faults in a program.  ...

Multiverse Debugging: Non-Deterministic Debugging for Non-Deterministic Programs (Artifact) [article]

Robbert Gurdeep Singh, Carmen Torres Lopez, Stefan Marr, Elisa Gonzalez Boix, Christophe Scholliers, Manuel Rigger, Maria Christakis
2019 Dagstuhl Artifacts Series (DARTS)  
Many of today's software systems are parallel or concurrent. With the rise of Node.js and more generally event-loop architectures, many systems need to handle concurrency.  ...  Therefore, some bugs may never be reproduced in the debugging session, because the conditions to trigger are not reached.  ...  The main reason why parallel programs are so difficult to debug is due to their non-determinism.  ...

Dieter Kranzlmüller
2001 Lecture Notes in Computer Science  
Yet, it is not intended as a complete replacement but as a plug-in for well-established, existing tools, which may utilize it to increase their debugging functionality.  ...  Debugging is accepted as one of the difficult tasks of high performance software development, which can be attributed to the high complexity of parallel and distributed applications.  ...  This means, that bigger systems are probably more difficult to debug than smaller systems.  ...
