The paper presents application of SIP protocol in the context of bag-of-tasks grid architecture. The SIP protocol has been used in realization of the execution management service. The main idea is use of stateful SIP proxy as request broker. The paper provides description of the concept, and the prototype system that has been built, as well as calculation of estimated performance level and it's relation...
Grid Computing is a domain in full development. The software known as middleware is upgraded and improved. Based upon this simple words, this paper will show how the software on the site RO-14-ITIM, from the National Institute for Research and development of Isotopic and Molecular Technology improved in the last four month from the European Middleware Initiative (EMI) 1 to version 3, the difficult...
The SBGrid Science Portal provides multi-modal access to computational infrastructure, data storage, and data analysis tools for the structural biology community. It incorporates features not previously seen in cyberinfrastructure science gateways. It enables researchers to securely share a computational study area, including large volumes of data and active computational workflows. A rich identity...
Distributed architecture is a fundamental way for science and engineering data application by aggregate power of computing resources connected by networks of the grid. This paper describes a innovative scenarios for intensive rainfall data analysis. The Flood Early Warning System is performed to give an alert in advance about the occurrence of heavy rainfalls around the world. The aim of the project...
Cloud computing is a computation or service based on concepts like virtualization, utility computing and grid computing provided to end users without requiring them to know the physical location of the system. Dynamic service management is achieved by implementing the cloud where dynamically scalable resources are provided as a service over the internet. In earlier works design of financial system...
Services and Infrastructures monitoring is a crucial issue in a distributed computing environment that involves all the Grid architecture layers, from the network to the single application service. In this paper we propose a multi layer model that aims to integrate monitoring applications of different subsystems and to offer management and resource presentation services to the end-user and to system...
Cloud computing, a rapidly developing information technology, has aroused the concern of the whole world. Cloud computing is Internet-based computing, whereby shared resources, software and information, are provided to computers and devices on-demand, like the electricity grid. Cloud computing is the product of the fusion of traditional computing technology and network technology like grid computing,...
Grid security is a key component in Grid computing. The mainstream Grid security solution, Grid Security Infrastructure (GSI) for Globus Toolkit (GT), offers comprehensive security services. This is achieved by applying public-key cryptography, cryptographic protocols methodologies and the necessary infrastructural supporting services in which public-key authentication framework (PKI) is the main...
The lack of license management schemes in distributed environments is becoming a major obstacle for the commercial adoption of Grid or Cloud infrastructures. In this paper, we present a complete license management architecture that enables a pay-per-use license management which can be deployed together with an on-demand computing scenario. Our architecture enables authenticated access to a remote...
Energy consumption of data centers has been in-creasing continuously during the last years due to rising demands of computational power especially in current Grid- and Cloud-Computing systems. One promising approach of reducing this energy consumption is the consolidation of servers by virtualization. Many low loaded computer systems are virtualized and run on few physical servers for reducing the...
This paper considers an InfiniBand connection between two bwGRiD clusters over a distance of 28 km in day-to-day production use. We discuss the hardware setup of InfiniBand messages converted and transported over a fiber optic connection. The two clusters can be operated as single system image, the batch system will enforce that all nodes for a job are allocated on one side of the cluster. This is...
It is a great idea to make many normal computers together to get a super computer, and this computer can do a lot of things. This is the concept of cloud computing. Cloud computing is an emerging model of business computing. And it is becoming a development trend. This article compares cloud computing and grid computing. Internet has connected all the computers in the world. Grid computing has been...
Cloud Computing is the evolution of the Grid Computing paradigm towards service-oriented architectures. The terminology applied to this kind of processing, when describing shared resources, refers to the concept of X as a Service. Such resources are available on demand and at a significantly lower cost compared to self-delivery of individual components (in addition to the price of suitable hardware...
The impact of Parallel Computing Infrastructures (PCI) on energy consumption and CO2 emissions worldwide can no longer be ignored. So far, most actions taken have focused on energy efficiency of PCI's underlying hardware, direct reduction of CO2 emissions, or user policies targeted to optimize hardware usage and consequently ensure that most CO2 emissions are justified, thereby minimizing the impact...
In this paper we present OpenMOLE, a scientific framework providing a virtualized runtime environment for distributed computing. Current distributed execution systems do not hide the hardware and software heterogeneity of computing and data resources whereas OpenMOLE provides generic services to develop distributed scientific algorithms independently from the execution environment architecture. OpenMOLE...
With the growing complexity of software applications, there is an increasing demand for solutions to distribute workload into server pools. Grid Computing provides powerful - but also highly complex - mechanisms to realize such tasks. Also, there is a steadily growing number of downtime-critical applications, requiring redundant servers to ensure service availability in case of component failures...
When it comes to grid and cloud computing, there is a lot of debate over their relations to each other. A common feature is that grids and clouds are attempts at utility computing. However, how they realize utility computing is different. The purpose of this paper is to characterize and present a side by side comparison of grid and cloud computing and present what open areas of research exist.
In this paper the authors address some methodological and technical issues on managing collections of digital documents published on the web by many different and autonomous stakeholders. To cope with this kind of problems the notions of document, of cooperative knowledge community, a set of cooperative content management system nodes glued together by a web semantic oriented middleware, and content...
With the increasing prevalence of large scale cloud computing environment, researchers has draw more attention about how to provide software as a service through the internet. In this paper, a novel approach named vSaaS is proposed in iVIC platform, which is the virtual computing environment for HaaS and SaaS applications. The aim of this approach is to provide the software as a service from a cloud...
Current computing platforms become more and more complex for users to use. To simplify configuration and deployment of applications on these infrastructures tools are necessary. Current deployment tools lack of maturity for large-scale deployment. For example a grid environment leads to a great diversity. Deploying an application on a grid from a single centralized machine is not adapt. So, decentralization...
