Minha: Large-Scale Distributed Systems Testing Made Practical

Nuno Machado, Francisco Maia, Francisco Neves, Fábio Coelho, José Pereira, Michael Wagner
2020 International Conference on Principles of Distributed Systems  
Testing large-scale distributed system software is still far from practical as the sheer scale needed and the inherent non-determinism make it very expensive to deploy and use realistically large environments  ...  Our experiments with two distributed systems show the usefulness of Minha in disclosing errors, evaluating global properties, and in scaling tests orders of magnitude with the same hardware resources.  ...  We believe that Minha opens a number of interesting research opportunities in the field of distributed systems testing and debugging.  ...

Agile Scalability for Large Scale Projects: Lessons Learned

Hina Saeeda, Fahim Arif, Nasir Mehmood Minhas, Mammona Humayun
2015 Journal of Software  
Agile has proved to be successful in the small and medium size project, however, it have several limitations when applied on large size projects.  ...  Based on it, we can judge the limitations of agile scalability for large size projects and can think of some remedial approach for overcoming these limitations in future.  ...  In large-scale systems, the coordination of different people generally results in a team of teams' system.  ...

Towards Launching AI Algorithms for Cellular Pathology into Clinical Pharmaceutical Orbits [article]

Amina Asif, Kashif Rajpoot, David Snead, Fayyaz Minhas, Nasir Rajpoot
2021 arXiv   pre-print
More such initiatives with large-scale publicly available datasets are required for developing effective DL solutions.  ...  When employing statistical tests, the underlying assumptions regarding distribution of data and the applicability of tests should be checked.  ...

AnoNet: Weakly Supervised Anomaly Detection in Textured Surfaces [article]

Manpreet Singh Minhas, John Zelek
2019 arXiv   pre-print
We tackle the problem of teaching a network with a low number of training samples with a system we call AnoNet.  ...  Even though an over-fit model can have a good performance on the training data, it does not generalize well and has poor performance on the testing data and does not scale to other testing data.  ...  Also, the network was not tested on any real world data-set which raised concerns regarding its practical application. The paper lacked quantitative analysis for the segmentation task.  ...

Rational thoughts in neural codes [article]

Zhengwei Wu, Minhae Kwon, Saurabh Daptardar, Paul R Schrater, Xaq S Pitkow
2019 bioRxiv   pre-print
Large-scale tasks are being solved with neural networks (65, 66) that provide rich state representations, but may not permit interpretation.  ...  We applied our method only to a fairly simple task, but our framework is quite general and can scale to much more complex tasks, and can model common errors of cogntive systems.  ...

Accordion

Marco Serafini, Essam Mansour, Ashraf Aboulnaga, Kenneth Salem, Taha Rafiq, Umar Farooq Minhas
2014 Proceedings of the VLDB Endowment  
Providing the ability to elastically use more or fewer servers on demand (scale out and scale in) as the load varies is essential for database management systems (DBMSes) deployed on today's distributed  ...  In this paper we present Accordion, a dynamic data placement system for partition-based DBMSes that support ACID transactions (local or distributed).  ...  In practice, however, longer reconfigurations end up being less effective as shown by our experiments. We have also tested the impact of reconfiguration on YCSB.  ...

Bottom-Up Coarse-Grained Modeling of DNA

Tiedong Sun, Vishal Minhas, Nikolay Korolev, Alexander Mirzoev, Alexander P. Lyubartsev, Lars Nordenskiöld
2021 Frontiers in Molecular Biosciences  
The so-called bottom-up coarse-graining practice separates fast and slow dynamic processes in molecular systems by averaging out fast degrees of freedom represented by the underlying fine-grained model  ...  AUTHOR CONTRIBUTIONS All authors listed have made a substantial, direct and intellectual contribution to the work, and approved it for publication.  ...  It is why force matching usually produces particle distributions different from the FG reference distributions in practice.  ...

Exploiting coroutines to attack the "killer nanoseconds"

Christopher Jonathan, Umar Farooq Minhas, James Hunter, Justin Levandoski, Gor Nishanov
2018 Proceedings of the VLDB Endowment  
Our focus is on understanding the practicality of using coroutines to improve throughput of such data structures.  ...  Database systems use many pointer-based data structures, including hash tables and B+-trees, which require extensive "pointerchasing."  ...  Coroutines are stackless, so they must potentially allocate frames for each coroutine call, which could be slow; in practice, our experiments show that the cost of managing coroutine frames can be made  ...

An Empirical Analysis of Assortment Similarities Across U.S. Supermarkets

Minha Hwang, Bart J. Bronnenberg, Raphael Thomadsen
2010 Marketing science (Providence, R.I.)  
We explain this difference using extant work on the minimal efficient scale of supermarkets and on local demand effects. Furthermore, we investigate the distribution and role of regional brands.  ...  "Value" regional brands are primarily distributed by supermarket firms without store brands, whereas the distribution of "premium" regional brands is unrelated to the presence of store brands.  ...  Similarly, Ellickson (2007) offers an account of the cost savings that can be gained through an efficient distribution system.  ...

The Determinants of Assortment Composition and Assortment Size at U.S. Supermarkets

Minha Hwang, Bart J. Bronnenberg, Raphael Thomadsen
2008 Social Science Research Network  
From the large chain-level effects on assortment, we conclude that marginal assortment decisions are mostly cost driven, and are made at the corporate level.  ...  We discuss our findings in the context of manufacturers designing distribution policies.  ...  However, relatively little is known empirically about how product assortment composition decisions of supermarkets are made in practice and how they differ across stores.  ...
