“…In such ways, instances of SG, which can provide access to many different sets of distributed resources for specific scientific domains, can be quickly developed by customising specific SG frameworks. Examples of SG frameworks include: The CSGF [13], Web Services Parallel Grid Runtime and Developer Environment Framework (WS-PGRADE/GUSE) workflow system [14], the Vine Toolkit [15], GridPort [16] and a Framework for Domain-Specific Science Gateways (InSilicoLab) [17]. These SG frameworks are more generic and are usually not specialised for a certain scientific domain.…”

The benefits of using e-Infrastructure environments, such as cloud, grid, and high performance computing, for performing scientific experiments could be quite significant. In particular, modeling and simulation, which can serve as a key decision making and system analysis tool, could benefit immensely from such environments ranging from issues of how a community of practice could access a simulation to how it could be run quickly. However, the access and use of these e-Infrastructure environments may present a completely different set of challenges, most especially for non-ICT users. Science Gateways (SG), which are digital interfaces to advanced technologies, can be used to overcome the challenges of running many simulations on e-Infrastructures in a reasonable amount of time. In this work, we developed a SG, based on the Liferay portal framework and the Catania grid and cloud engine. We show how an Agent-Based infection simulation, which has been implemented using the Recursive Porous Agent Simulation Toolkit (REPAST) Simphony, can be ported to a Science Gateway and deployed on distributed computing infrastructures. This demonstration illustrates how this technology can be used easily to allow multiple users across the world to access a simulation and to execute their applications in an e-Infrastructures environment.

“…The framework WS-PGRADE/gUSE [4] [5] has been used to develop several Science Gateways, such as MoSGrid [6] in the field of Life Science, and VisIVO [7] and CTA Science Gateway [8] in Astrophysics. In MoSGrid, Information Technology (IT) skilled users implement services and workflows for molecular simulations which can be reused by scientists to build their own experiments.…”

An e cient exploitation of Distributed Computing Infrastructures (DCIs) is needed to deal with the data deluge that the scientific community is facing, in particular the Astrophysics one due to the emerging Square Kilometre Array (SKA) telescope that will reach data rates in the exascale domain. Hence, Science Gateways are being enriched with advanced tools that not only enable the scientists to build their experiments but also to optimize their adaptation to di↵erent infrastructures. In this work we present a method, called "two-level workflow system", to build this kind of tools and we apply it to a set of analysis tasks of interest for some use applications to the SKA. This method uses the Software-as-a-Service model to keep the scientists insulated from technical complexity of DCIs, and the COMPSs programming model to achieve an e cient use of the computing resources.

SummaryThe availability of large‐scale digital surveys offers tremendous opportunities for advancing scientific knowledge in the astrophysics community. Nevertheless, the analysis of these data often requires very powerful computational resources. Science gateway technologies offer Web‐based environments to run applications with little concern for learning and managing the underlying infrastructures that execute them. This paper focuses on the issues related to the development of a science gateway customized for the needs of the astrophysics community. The VisIVO Science Gateway is wrapped around a WS‐PGRADE/grid User Support Environment portal integrating services for processing and visualizing large‐scale multidimensional astrophysical data sets on distributed computing infrastructures. We discuss the core tools and services supported including an application for mobile access to the gateway. We report our experiences in supporting specialized astrophysical communities requiring development of complex workflows for visualization and numerical simulations. Further, available platforms are discussed for sharing workflows in collaborative environments. Finally, we outline our vision for creating a federation of science gateways to benefit astrophysical communities by sharing a set of services for authentication, computing infrastructure access and data/workflow repositories.
