As the development of Internet and mobile device increases, there is a correspondingly increasing amount of data produced by users of such technology worldwide. It is thus essential to analyze such massive amounts of data reflective of the big data era. Recently, Apache Spark has become popular for analyzing big data, since it can process streaming data and support real-time in-memory computing. Also,...
High Performance Computing (HPC) applications require systems with environments for maximum use of limited resources to facilitate efficient computations. However, these systems are faced with a large trade-off between efficient resource allocation and minimum execution times for the applications executed on them. Also, deploying applications in newer environments is exacting. To alleviate this challenge,...
Appearance of Science Clouds enables scientists to facilitate large-scale scientific computational experiments over cloud environment. Many task computing (MTC) in computational science needs to certificate stable executions of applications even in rapid changes of vital status of physical resources and supports high performance resources in a long period. Auto-scaling approach on virtual machines...
The rapid advent of computing technology enables scientists to expand their research infrastructure over supercomputer-on-demand using a resource leasing service on pay-per-use basis. This infrastructure service is called as Science cloud which provides uniform user interface to scientific experiments over large-scale heterogeneous resources. In spite of the strength of conveniences, it is difficult...
Grids have ensured to solve a large-scale complex scientific problem with utilizing many heterogeneous resources that are geographically separated. However, as grid resources and scientific applications become diverse, the difficulty of their execution management and control has been increased. In this paper, we propose JARS (Job history-based Adaptive grid Resource Selection) system and evaluate...
Cloud computing has recently paid attention as a way to share the resources to provide scalable and on-demand services. Across various authorities, cloud resources should be configured to a virtual organization (VO) according to user's requirements. Ontology-based representation of cloud computing environment would be able to conceptualize common attributes among cloud resources and to represent semantic...
