Application hosting services for research community on hierarchical grid infrastructure

This paper describes the application hosting services (AHS) that is one of software component of multiple grid environments middleware developed by RENKEI (REsources liNKage for E-scIence) project. The purpose of this middleware realizing the federate/share resources (computers, storages, databases and applications) distributed among multiple grid environments, such as research laboratories, national computer centers and international grids etc. AHS provides repository of application information to the research community created by grid virtual organization (VO).
