Abstract Science gateways can provide access to distributed computing resources
and applications at very different levels of granularity. Some gateways do not even
hide the details of the underlying infrastructure, while on the other hand some
provide completely customized high-level interfaces to end-users. In this chapter
the different granularity levels at which science gateways can be developed with
WS-PGRADE/gUSE are analysed. The differences between these various granu-
larity levels are also illustrated via the example of a molecular docking gateway and
its four different implementations.
8.1 Introduction
Science gateways, such as gateways built using the WS-PGRADE/gUSE frame-
work (Kacsuk 2012), have the potential to offer transparent and user-friendly access
to a wide variety of distributed computing resources. These tools hide the com-
plexity of the underlying infrastructure from the scientist end-users and let them
concentrate on their scienti
c research problem instead of requiring a steep and
sometimes impossible learning curve in complex computing paradigms.
