Database connectivity is considered to be an important crosscutting, nonfunctional requirement that inevitably impacts the overall, runtime performance measures of the running web application. It is also a requirement that needs systematic resolution at the early phases of designing the web application under development due to its crosscutting nature. Database connection pooling can be seen as one of the more efficient solutions that will enhance the run-time performance of web/database transactional activities. Our work asserts that adopting an aspect-oriented approach for database connection pooling in web based systems promises for an even better improved run time performance of web based systems. In this study we analyze the run-time effects that result from applying three approaches upon cross cutting concerns of database connectivity in a developed web application. The three approaches are: An aspect-oriented approach (AOP), an object-oriented approach (OOP) or (Pool), and sequential calls to the native database driver approach (Native). The run-time effects were translated into run-time performance measures, namely, the average response time and successful hits percentage. We were able to demonstrate the added benefit of using an aspect-oriented approach for this problem.","PeriodicalId":375277,"journal":{"name":"2011 9th IEEE/ACS International Conference on Computer Systems and Applications (AICCSA)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130660387","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}

Fundamental design choices for distributed resource advertising and querying are evaluated in the context of existing practical systems. First, a generic model for cost of resource discovery is presented. Second, multi-attribute resource and query characteristics from Planet-Lab and SETI@home are presented. We observe that attributes of both resources and queries are highly skewed, correlated, queries are less specific, and Generalized Pareto distribution is suitable for capturing the distribution of most dynamic attributes and their rate of change. Based on these observations, different design choices are evaluated for resource discovery in terms of their cost of advertising/querying, latency, load balancing, and routing table size. The findings indicate that superpeer-based architectures have the potential to support large-scale resource aggregation as they simultaneously balance the cost and load.","PeriodicalId":375277,"journal":{"name":"2011 9th IEEE/ACS International Conference on Computer Systems and Applications (AICCSA)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129739943","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}

We focus on a concise example — the most likely genetic causes of a particular form of inherited hearing loss — ADNSHL. Whereas the cost and throughput involved in the collection of genomic data have advanced dramatically during the past decade, gathering and interpreting clinical information regarding disease diagnosis remains slow, costly and error-prone. AudioGene employs machine-learning techniques in an iterative procedure to prioritize probable genetic risk factors of disease, which are then verified with a molecular (wet lab) assay. In our current implementation AudioGene achieves 67% first-choice accuracy (versus 23% using a majority classifier). When the top three choices are considered, accuracy increases to 83%. This has numerous implications for reducing the cost of genetic screening as well as increasing the power of novel gene discovery efforts. While AudioGene is focused on hearing loss, the design and underlying mechanisms are generalizable to many other diseases including heart disease, cancer and mental illness.","PeriodicalId":375277,"journal":{"name":"2011 9th IEEE/ACS International Conference on Computer Systems and Applications (AICCSA)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126976977","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}

The energy cost produced by supercomputers during the lifetime of the installation is similar to acquisition. Thus, besides its impact on the environment, energy is a limiting factor for the HPC. Our research aims to reduce the energy consumption of computer systems to run parallel HPC applications. In this article we analyse the possible influence on the energy consumption of parallel programming paradigms of shared memory (OpenMP) and message passing (MPI), and the behaviour of systems at different clock frequencies of CPUs. The results show that the programming model has a major impact on the energy consumption of computer systems. It was found that the impact of reduced clock frequencies on the execution time, energy efficiency, and maximum power consumption depends not only on the type of application but also on its implementation in a specific programming model. We believe that another criteria to consider when choosing a parallel programming model is the impact on energy consumption.","PeriodicalId":375277,"journal":{"name":"2011 9th IEEE/ACS International Conference on Computer Systems and Applications (AICCSA)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115056633","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}
