Querying Large Physics Data Sets Over an Information Grid
Optimising use of the Web (WWW) for LHC data analysis is a complex problem
and illustrates the challenges arising from the integration of and computation
across massive amounts of information distributed worldwide. Finding the right
piece of information can, at times, be extremely time-consuming, if not
impossible. So-called Grids have been proposed to facilitate LHC computing and
many groups have embarked on studies of data replication, data migration and
networking philosophies. Other aspects such as the role of 'middleware' for
Grids are emerging as requiring research. This paper positions the need for
appropriate middleware that enables users to resolve physics queries across
massive data sets. It identifies the role of meta-data for query resolution and
the importance of Information Grids for high-energy physics analysis rather
than just Computational or Data Grids. This paper identifies software that is
being implemented at CERN to enable the querying of very large collaborating
HEP data-sets, initially being employed for the construction of CMS detectors.Comment: 4 pages, 3 figure
Towards collaborative learning via shared artefacts over the Grid
The Web is the most pervasive collaborative technology in widespread use today; and its use to support
eLearning has been highly successful. There are many web-based Virtual Learning Environments such as
WebCT, FirstClass, and BlackBoard as well as associated web-based Managed Learning Environments. In
the future, the Grid promises to provide an extremely powerful infrastructure allowing both learners and
teachers to collaborate in various learning contexts and to share learning materials, learning processes,
learning systems, and experiences. This position paper addresses the role of support for sharing artefacts
in distributed systems such as the Grid. An analogy is made between collaborative software development
and collaborative learning with the goal of gaining insights into the requisite support for artefact sharing
within the eLearning community

Distributed simulation and the grid: Position statements
The Grid provides a new and unrivaled technology for large scale distributed simulation as it enables collaboration and the use of distributed computing resources. This panel paper presents the views of four researchers in the area of Distributed Simulation and the Grid. Together we try to identify the main research issues involved in applying Grid technology to distributed simulation and the key future challenges that need to be solved to achieve this goal. Such challenges include not only technical challenges, but also political ones such as management methodology for the Grid and the development of standards. The benefits of the Grid to end-user simulation modelers also are discussed
ClouNS - A Cloud-native Application Reference Model for Enterprise Architects
The capability to operate cloud-native applications can generate enormous
business growth and value. But enterprise architects should be aware that
cloud-native applications are vulnerable to vendor lock-in. We investigated
cloud-native application design principles, public cloud service providers, and
industrial cloud standards. All results indicate that most cloud service
categories seem to foster vendor lock-in situations which might be especially
problematic for enterprise architectures. This might sound disillusioning at
first. However, we present a reference model for cloud-native applications that
relies only on a small subset of well standardized IaaS services. The reference
model can be used for codifying cloud technologies. It can guide technology
identification, classification, adoption, research and development processes
for cloud-native application and for vendor lock-in aware enterprise
architecture engineering methodologies
A COLLABORATIVE MODEL FOR VIRTUAL ENTERPRISE
Collaborative process characteristics have three dimensions: actors, activities and actionâs logic. The aim of this paper is to present a virtual portalâs model that helps managing consortiums. Our model based on dynamic e-collaboration and it has a modular structure, multilayer approach. Systemâs functionality of virtual enterprise is collaborative model is concern on usersâ login, based on role and access control, searching and providing distributed resources, accessibility, metadata management and improved informationâs management. Our proposal for developing solution offers a functional architecture of a virtual enterprise using dynamic e-collaboration and shared space.dynamic e-collaboration, multilayer solution, modular approach
