creation is required. However, the con
guration interface (as it facilitates full
workflow con
guration) is rather complex, with different panels for jobs and ports.
On the provider side, this scenario, besides system administrators who deploy
the gateway, also requires specialized workflow application developers who design,
implement and maintain the workflows for the users.
The common feature of the
first two granularity levels is that no custom inter-
faces are created for the applications. Only the standard WS-PGRADE/gUSE
submission interfaces are used in the form that these features were described in the
previous chapters of this topic.
8.6 Granularity Level 3: End-User View
Granularity level 3 utilizes the end-user view of WS-PGRADE/gUSE. This view
enables the generation of customized user interfaces without writing additional
code.
In this scenario, system administrators deploy the gateway, workflow developers
develop the necessary workflows, and then the end-user interfaces are automatically
created by WS-PGRADE/gUSE, based on the workflow settings provided by the
developers. The framework enables workflow developers to de
ne templates on top
of concrete workflows (by differentiating between
fixed and open parameters from
