NAREGI is a 5-year Japanese National Grid Project during 2003–2007, whose chief aim is to develop a set of grid middleware
to serve as a basis for future e-Science. NAREGI also aims to lead the way in standardization of grid middleware, based on
the OGSA architecture. Its super-scheduler is based on the proposed OGSA-EMS Architecture, in that it becomes the first working
implementation that implements the documented component relationships within the OGSA-EMS architecture document v.1.0. Through
the efforts and experience in the design and implementation, it has been confirmed that the documented OGSA-EMS architecture
is quite feasible, but will require significant amount of refinement and speed improvements to finalize its detailed specifications.
The super-scheduler also supports co-allocation across multiple sites to support automated execution of grid-based MPIs that
execute across machines. Such a resource allocation requires sophisticated interactions between the OGSA-EMS components not
covered in the current OGSA-EMS architecture, some of which are non-trivial. Overall, job scheduling with OGSA-EMS has proven
to not only work, but also that its job allocation and execution time is within reasonable bounds.
