SAGA-based user environment for distributed computing resources: A universal Grid solution over multi-middleware infrastructures
Go IWAI, Y. Kawai, T. Sasaki, Y. Watase · Procedia Computer Science · 2010
This paper demonstrates practical applications based on SAGA–A Simple API for Grid Applications–for distributed computing resources over multi-middleware infrastructures. SAGA provides a high-level programming interface that bridges between applications and Grids as well as local schedulers such as PBS. At the Computing Research Center of KEK, we are playing a role to support not only on-site users, but also domestic university groups in the High Energy and Nuclear Physics (HENP) community. In order to provide a more effective and practical client environment to users, we have developed Grid-adaptive applications based on SAGA as a part of activity in the REsources liNKage for E-scIence (RENKEI) for the general purpose e-Infrastructure using National Research Grid Initiative (NAREGI) middleware. We present the technical details for the user environment demonstrator and discuss the usability by real HENP applications.
