Automated tools for detecting energy inefficiency bugs have been shown to be effective. Existing approaches generally consist of two parts, namely the simulation part and the monitor part. The simulation part explores an application's state space guided by an application execution model, and the monitor part checks for occurrences of energy inefficiency patterns. However, existing approaches might miss energy inefficiency bugs due to their imprecise application execution models and oversimplified energy inefficiency diagnosis policies. In this paper, we proposed NavyDroid, an approach to diagnosing energy inefficiency problems more effectively. We summarized a comprehensive application execution model from Android specifications and expressed it as a state machine. By considering multiple patterns of wake lock misuses, our approach is able to detect more complex energy bugs caused by wake lock misuses. We implemented NavyDroidon top of Java Pathfinder (JPF) and applied it to real-world applications. We evaluated NavyDroid with 17 real-world Android applications, and NavyDroid located more energy inefficiency bugs in these applications than the existing work E-GreenDroid did. The results of our experiments demonstrate that our approach can effectively locate real energy inefficiency bugs in Android applications, suggesting its effectiveness.","PeriodicalId":349438,"journal":{"name":"Proceedings of the 9th Asia-Pacific Symposium on Internetware","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123434176","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}

Existing SSD caching schemes are mainly driven by VM-centric metrics. They treat the VMs as independent units and focus on critical low-level performance metrics of individual VMs, such as the working set, the IO latency, or the throughput. However, for elastic Hadoop applications consisting of multiple VMs, the workload is rapidly changing, and the importance of differnet VMs may be different even if they have the same low-level IO pattern. In this situation, the VM-centric SSD caching schemes may not lead to the best performance, i.e., the shortest job completion time. Considering the importance of VMs and relationships among VMs inside the application may potentially better improve the performance, which we regard as the application-centric metrics. We propose the Application-Centric SSD caching for Hadoop applications (ACSSD), which reduces the job completion time from the application level. AC-SSD uses the genetic algorithm based approach to calculate the nearly optimal weights of virtual machines for allocating SSD cache space and controlling the I/O Operations Per Second (IOPS) based on the importance of the VMs. Moreover, AC-SSD introduces the closed-loop adaptation to face the rapidly changing workload. The evaluation shows that AC-SSD reduces the job completion time by up to 39% for IO sensitive workloads, and up to 29% for rapidly changing workloads.","PeriodicalId":349438,"journal":{"name":"Proceedings of the 9th Asia-Pacific Symposium on Internetware","volume":"207 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133298484","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}

Existing work has already achieved good results in extracting code elements (classes, methods, etc.) from software documents. However, it will lead to a lot of noise links if we link a document to all the code elements existing in it. In this paper, we propose an approach to identify the contextual code elements and the salient code elements in a software document, then we can weight the traceability links between source code and software document so that those noise traceability links can be filtered effectively. We measure the saliency of each code element in a document with four kinds of document-related features and three kinds of code-related features, and we adopt TransR-based code embedding technology to evaluate the distance between code elements. In the experiments, we get a precision of 70.7% in recognizing salient code elements of StackOverflow answer documents, which is more than 12% improvement compared with Rigby's work. At the same time, we can filter about 56.5%~69.3% noise traceability links compared with the RecoDoc approach. It will improve the quality of traceability links between source code and related software documents.","PeriodicalId":349438,"journal":{"name":"Proceedings of the 9th Asia-Pacific Symposium on Internetware","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127363677","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}

Considering the complexity of distributed software development, it is important to understand the variation of various tasks, so the projects could work more efficiently on plan formulation, personnel organization, or task allocation. The main goal of this paper is to understand the variations of software development tasks. We conduct an interview with 47 interviewees and a survey with 148 people from 15 projects with different size and domain.Through the analysis of interviews and surveys, we find that a software task could be characterized through three aspects: value, difficulty and centrality. Among them, task value is influenced by the role of stakeholders and project context, and is related to the task difficulty and task centrality. Task difficulty is reflected by technology, domain difference, working relationships, customer related issues, and it is also related to the developers' personalities. Task centrality can be described by customer impact, system-wide impact, team impact and future impact. We believe our results can help project managers to optimize task allocation, or adjust project plan, and thus achieve efficient development.","PeriodicalId":349438,"journal":{"name":"Proceedings of the 9th Asia-Pacific Symposium on Internetware","volume":"6 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126072025","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}
