usage of Grid infrastructures is one of the best available options. Grid can provide
the computing resources needed by the services, with a strong security that provides
the trustworthiness of the platform.
Within the framework of this short BEinEIMRT experiment, the e-IMRT plat-
form has been upgraded with several BEinGRID common capabilities. Using
BEinGRID SLA Negotiation component, which has been plugged into GridWay
metascheduler (Huedo et al. 2004, Llorente et al. 2005), the platform has acquired
the capacity of negotiating CPU capacity on demand among a set of pre-selected
providers. Additionally, the security of the exposed web services interface has been
improved with the integration of two new components which verify the content
of the received requests and check the authorization of the user to perform such
operations. Also, the Business Experiment has started the validation of the methods
and the platform within the hospital, and analyzed the viability from a commercial
point of view. The experiment has involved the participation of several partners with
different roles:
• Centro de Supercomputación de Galicia (CESGA) in Spain. It acted as Grid
application provider and as the front-end for the final user. It had adapted the
services to the usage of Grid infrastructure. In the future, it could sell the solu-
tion, both as a service and as a product and will grant licenses for third parties.
Also, it could be a Grid provider for third parties that commercialize the service
or for hospitals that want to have the product installed in-house.
• Radiophysics Research Group of the University of Santiago de Compostela in
Spain. It acted as technology and knowledge provider. It provided the expertise
in Medical Physics, and developed the backend solutions for verification and
optimization of treatment plants. In the future, this group will generate new solu-
tions as well as support the Grid application provider in the extension (including
more models of Linacs from other manufacturers) and other improvements to
the platform.
• Information Technology Group of the University of Vigo in Spain. It acted also
as a technology provider. It had developed the web front-end, the web services
and deployed the security solutions. In the future, this partner will adapt the
interface to the technological evolution and to the new solutions.
• Distributed Systems Architecture Group of the Universidad Complutense de
Madrid, Spain. This third technological provider has collaborated in the integra-
tion of GridWay into the platform. It has designed the SLA integration with this
metascheduler.
• Fundación IDCHUS. It is the Research Foundation of the Complexo Hospitalario
de la Universidad de Santiago (CHUS), Spain. It acted as the final user (as it
is), defining requirements, and validating the generated solution from the plat-
form. Hospitals like CHUS are the only ones that can test the new solutions for
clinical usage, which is a must for commercial success of solutions in the health
sector. So, a stable agreement with one or, better, several hospitals is necessary
for the future. They help to identify new requirements and validate them before
commercialization.
