In-Depth Information
The central component of the project is the WS-PGRADE/gUSE gateway
framework. This is the basis of all the SG instances developed by project partners,
subcontractors, and associated partners. During the project the WS-PGRADE/gUSE
framework has been signi
cantly further developed, including the following main
features:
1. Cloud integration via the CloudBroker Platform (this is described in detail in
Chap.
7
) to access a large variety of commercial and academic clouds
3. To provide robot certi
cates (see details in Chap.
6
)
4. To provide an ef
cient and
flexible data management system over various DCIs
(see details in Chap.
5
)
5. To extend the work
ow management system with work
ow debugging capa-
bilities (see details in Chap.
2
)
Of course, not only was the functional extension a major goal in the project but it
also made the framework robust and ef
cient in the sense that a large number of
users (in the range of 100
1,000) could simultaneously use it with short response
times and the gateway should be able to handle even millions of simultaneous job
submissions. Another important aspect was the improvement of the gateway
installation procedure, for which an installation and a service wizard have been
developed. The documentation of the framework was also significantly improved. It
contains 14 documents in the following 4 series:
-
1. Blue series for end-users (2 documents)
2. Green series for gateway administrators (5 documents)
3. Red series for work
ow developers (3 documents)
4. Orange series for general purposes (4 documents)
The gateway framework is published at SourceForge (
https://sourceforge.net/
projects/guse/
)
and has become very popular. There have been over 15,000
downloads as of the writing this topic. The user forum is very active, and nearly 200
different topics are discussed by a large number of participants. The further
development of the WS-PGRADE/gUSE gateway framework will not be stopped
when the SCI-BUS project is over at the end of September 2014. The project has
also developed a sustainability plan that, together with the large number of users,
guarantees the further progress of the WS-PGRADE/gUSE gateway framework. A
roadmap of development goals with their expected deadline is found on the SCI-
BUS web page (
http://www.sci-bus.eu
), which will be maintained even after SCI-
BUS project is
finished.
