High Performance Computing (HPC) with the modern trend to multi-core clusters accentuates the importance of parallelism and multithreading. This paper presents a Java based message passing implementation, named Architecture for Java Universal Message Passing (A-JUMP). A-JUMP provides flexibility to programmers in writing parallel applications using multiple programming languages. Moreover, it also provides facility to use different network protocols for message communication. The backbone of A-JUMP is HPC bus that facilitates the development of parallel applications. It provides the interoperability between different hardware resources, communication protocols and mediums. The HPC bus is built upon well-established industry standards; Java Messaging Service (JMS) and Java programming language. In HPC bus, ActiveMQ is solely responsible for communication and message passing in an asynchronous manner. The communication layer of A-JUMP is disentangled from the rest of HPC bus implementation that ensures that any changes in communication protocol and network topology will remain transparent to the end users. The components of A-JUMP includes; Job Scheduler, Monitoring, Machine Registry, and Code Migrator/Execution other than HPC bus. In addition, it includes a set of easy to use APIs for writing MPI-like code. The results demonstrate promising performance for standard benchmarks like ping pong latency tests and embarrassingly parallel (EP) code execution. The comparison of these results with MPICH and MPJ Express are also presented.","PeriodicalId":434420,"journal":{"name":"International Conference on Frontiers of Information Technology","volume":"89 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133758195","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}

Energy efficient buildings will have a significant impact on overall energy consumption and greenhouse gas emissions. Buildings being multi-scale, multi-physics, highly uncertain dynamic systems, its energy efficiency is directly linked with the design and control of various systems in buildings. Achieving substantial levels of energy savings over the life-time of a building require not only the state-of-the-art hardware technology but also a thorough computational framework which includes mathematical algorithms, computational science methodologies and computer tools targeted for rapid analysis, optimization and control. Direct application of high fidelity simulation models to problems of optimal design and control is not feasible. Thus, reduced-order models are often developed for an efficient design and control. In this study, we present the application of high performance computing tools to perform high fidelity flow simulations in a typical room which serves as a basic unit in a building. Using a large data set of the flow and temperature field distributed among various processors, we compute optimal basis functions in parallel. These basis functions are used in developing reduced-order models of complex systems for control and optimization purposes.","PeriodicalId":434420,"journal":{"name":"International Conference on Frontiers of Information Technology","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134421361","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}

A lot of effort has been made to reduce infant mortality but it remains high in most of the developing countries and the underdeveloped world. Perinatal Mortality is a cause of great emotional pain and social unrest. The main cause of pregnancy failure in the developed world is obesity but in the under-developed world the main cause remains malnutrition. However, their are a mix of factors that affect pregnancy failure in the developing countries. Pakistan has a very high infant mortality rate which stands at 78 deaths per 1000 births. The reasons for this are many including lack of proper healthcare. This is because of a severe shortage of healthcare professionals and specialists in Pakistan. The gap in healthcare may be overcome by leveraging IT to provide automated healthcare. In this paper, we show how machine learning may be used to predict perinatal failure. We examine the relationship between pre-pregnancy weight, weight gain during pregnancy and the body mass index (BMI) to investigate how they relate to foetal failure. We employ the K Nearest Neighbor (K-NN) technique to automatically differentiate between successful and failed pregnancies. Our method is able to predict the the outcome of a pregnancy with about 95% accuracy.","PeriodicalId":434420,"journal":{"name":"International Conference on Frontiers of Information Technology","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122043469","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}
