Abstract:
Especially within Grid infrastructures driven by high-performance
computing (HPC), collaborative online visualization and steering (COVS) has become an important technique to dynamically steer the parameters of a parallel simulation or to just share the outcome of simulations via visualizations with geographically dispersed collaborators. In earlier work, we have presented a COVS framework reference implementation based on the UNICORE Grid middleware used within DEISA. This paper lists current limitations of the COVS framework design and implementation related to missing fine-grained authorization capabilities that are
required during collaborative COVS sessions. Such capabilities use end-user information about roles, project membership, or participation in a dedicated Virtual Organization (VO). We outline solutions and present a design and implementation of our architecture extension that uses Attribute authorities such as the recently developed Virtual Organization Membership Service (VOMS) based on the Security Assertion Markup Language (SAML).
