In-Depth Information
Furthermore, a mobile application named VisIVO Mobile was developed to
provide astrophysical visualization on mobile devices by connecting them to data
repositories and workflows of the gateway. The mobile application shares the same
accounts as the gateway, and offers research groups and communities an exciting
possibility to share results and experiences of analysis and exploration of astro-
physical datasets within a collaborative visualization environment.
This chapter describes the design, architecture, and implementation details of
VisIVO Science Gateway and VisIVO Mobile, focusing on how they have been
built using the WS-PGRADE/gUSE framework. It also discusses the additional
features that have been developed to address the requirements of the astrophysics
community.
13.2 Systems Architecture
VisIVO Science Gateway and VisIVO Mobile are developed on top of
WS-PGRADE, providing access to VisIVO tools (Becciani 2010), enabling the
execution of a comprehensive collection of modules for processing and visualiza-
tion of astrophysical datasets on DCIs.
The architecture of the VisIVO Science Gateway and VisIVO Mobile has a
distributed con
guration on different machines as shown in Fig.

frontend services contain the user interfaces to interact with the gateway. The main employed
gUSE technologies to develop the VisIVO Portlets and VisIVO Mobile are also depicted
