Often, students learn about the logical errors in parallel programs and troubleshoot them through trial and error, and spend a significant amount of time and effort in the process. A systematic pedagogical approach to teaching parallel code correctness is therefore needed to enhance the productivity of students and instructors. In this paper, we describe some theoretical and practical approaches that can be adopted for assessing and teaching parallel code correctness. The theoretical approaches include using formal methods (e.g., Petri nets and Hoare Logic). We apply these approaches on the test cases discussed in this paper. The practical approach involves teaching code correctness through demonstrations. For enabling this, we have not only curated a repository of parallel programs with commonly made logical errors but have also added a high-level interface on top of the repository for quickly comparing fixed and incorrect versions of the sample code in the repository, seeing the explanation text on the errors, and searching the repository on the basis of the causes and symptoms of logical errors. The work presented in this paper can potentially motivate the instructors in including the content on code correctness in their parallel programming courses and trainings.","PeriodicalId":223719,"journal":{"name":"2019 26th International Conference on High Performance Computing, Data and Analytics Workshop (HiPCW)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127553967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This demand from residences has seen consistent growth over the last decade. In developing nations like India, this demand is also a significant contributor to greenhouse emissions, given that we are starting from a lower base compared to other countries. Our understanding in this space though is still limited. One of the key reasons for this is lack of availability of open data sources on household's ownership, usage patterns of appliances and key socio-economic indicators which are critical in gaining insights into demand patterns of households. We outline the methodology for designing and executing a statistically representative survey to collect data to understand and analyze residential electricity demand, presenting the case study of a primary representative survey we conducted in urban Bangalore covering 403 households. We also present the methodology for development of a model to build residential load curves at hourly resolution. We analyze three primary questions; how do households in different income-representative brackets consume electricity, what is the variation in consumption between these brackets and what are key appliance groups that contribute to this variance. We also look at generation profiles from solar PV installations to see what times of the day demand can be met from these renewable sources. In the process, we also examine the rooftop policy in Karnataka and suggest any amendments that can be made to increase adoption of solar rooftop to meet some of this demand locally, based on the analysis of load curves.","PeriodicalId":223719,"journal":{"name":"2019 26th International Conference on High Performance Computing, Data and Analytics Workshop (HiPCW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130688923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Visually Introducing Freshmen to Low-Level Java Abstractions for Creating, Synchronizing and Coordinating Threads 直观地向新手介绍创建、同步和协调线程的低级Java抽象

The driving problems are visualized simulations of multiple physical objects in motion that may (a) be confined to a shared space and (b) coordinate with each other. Such simulations do not require any domain-specific knowledge such as sorting and image processing for driving problems and exercises, and their implementation demonstrates the benefits of object-based programming. They allow focus on both the performance and programmability benefits of concurrency, provide analogies for an abstraction-independent explanation of concurrency concepts, and can be used to incrementally motivate all low-level concurrency abstractions and visualize the effect of using and not using these abstractions. Layered simulation-based worked examples illustrating the abstractions were presented and easily understood in multiple offerings of a course that implemented this approach. Students implemented non-trivial assignments based on these abstractions, even when they were optional, did not face major obstacles because of visual error feedback, and were excited by concurrency as they felt it empowered them to implement arbitrary applications early.","PeriodicalId":223719,"journal":{"name":"2019 26th International Conference on High Performance Computing, Data and Analytics Workshop (HiPCW)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123528553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their interest in HPC arises from their need to use it for research in their scientific domain having done some background courses in programming with Fortran/C/C++ and numerical methods. Very few Indian educational institutes offer a course/courses in parallel programming and the course is mostly offered in some of the high ranking engineering institutes. Even in the stream of Computer Science, the course if at all offered is an elective course. The non-Computer Science domain users that makeup as the majority of users of HPC in India do not possess sufficient background in Computer Science and gear up as HPC users mostly through self-study or short term training workshops that address their requirements. However, such training programmes are not a regular activity in India and cater to a broad audience with a varied level of aptitude in computing, programming, and simulation via mathematical modelling. In this paper, we discuss the current HPC education scenario and propose an education strategy to broaden the base of HPC users and to help researchers at all levels to effectively use HPC for their academic research and development work.","PeriodicalId":223719,"journal":{"name":"2019 26th International Conference on High Performance Computing, Data and Analytics Workshop (HiPCW)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114984911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
