accessing the functionalities of gUSE. The gUSE Remote API are employed from
the VisIVO Mobile application to con
gure and submit the VisIVO workflows on
VisIVO Science Gateway.
VisIVO Science Gateway and VisIVO Mobile deployment, operation, and main-
tenance have improved from the
first production release, based-on WS-PGRADE/
gUSE version 3.4.4, to the current production release based on WS-PGRADE/gUSE
version 3.6.1, mainly thanks to the following WS-PGRADE/gUSE features in the
latest versions:
Service wizard: a new gUSE tool for service checking and con
guration during
deployment of gUSE (gUSE version 3.4.6).
There have been some developments in system performance optimization on the
DCI Bridge side. The main result was for end-users because these developments
enabled signi
cantly faster job processing and submission (gUSE version 3.5.3).
Administrators can start/stop gUSE by some useful scripts instead of longer
manual step sequences (gUSE version 3.5.3).
Workflow developers can create robot permission associations for every sup-
ported resource type in WS-PGRADE/gUSE to identify VisIVO applications.
Therefore, any user can easily submit workflows identi
ed by robot permissions
without dealing with any authentication data e.g., for the grid infrastructure
(gUSE version 3.5.5).
Workflow export/import to/from the remote SHIWA repository to share work-
flows to a broader astrophysics community in WS-PGRADE format and in
SHIWA IWIR format as well (gUSE version 3.5.6).
Administrators can con
gure the remote API to be employed from VisIVO
Mobile setting them directly from the portal (gUSE version 3.5.8).
Use of the Data Avenue component enables an extension of the data manage-
ment portlet functionalities for data transfer between resources (gUSE version
3.6.0).
Workflow developers and advanced users can debug job submissions by
applying breakpoints in workflows. They can interact with workflows at runtime
directly, and can influence and change a workflow
s submission processes and
results by enabling or prohibiting the progress of job instances at breakpoints
(gUSE version 3.6.1).

The new WS-PGRADE/gUSE features of version 3.6.2, enabling direct cloud
access, will be investigated for future extensions of the VisIVO gateway to exploit
cloud infrastructures. Another relevant novelty is the option for the
def-
inition of job executables within the workflows. This new feature of WS-PGRADE
job con
“
remote
”
guration enables users to de
ne job executables by references in mobile
devices where the uploading of local
files of executables is not possible. This
feature will be adopted by VisIVO Mobile to con
gure the executables of a job.
