ZENTURIO: An Experiment Management System for Cluster and Grid Computing

Over the last de ade, a dramati in rease has been observed in the ability to generate and store data in the ourse of parameter studies, performan e analysis, and software testing. In this paper, we introdu e ZENTURIO, a sophisti ated experiment management environment that greatly alleviates parameter studies, performan e analysis, and software testing for a wide variety of target ar hite tures, in luding luster and Grid ar hite tures. ZENTURIO uses a novel dire tive-based language named ZEN in ombination with a user portal to spe ify arbitrary omplex program exe utions. Among others, ZEN enables to substitute strings, to request for performan e information, and to ontrol the number of experiments. ZENTURIO has been designed as a olle tion of Grid-servi es whi h omprise: (1) a registry servi e whi h supports registering and lo ating Grid servi es; (2) an experiment generator that parses les with ZEN dire tives and instruments appli ations for performan e analysis and parameter studies; (3) an experiment manager that ompiles and ontrols the exe ution of experiments on the target mahine. A graphi al user portal allows the user to ontrol and monitor the experiments and to automati ally visualize performan e and output data a ross multiple experiments. ZENTURIO has been implemented by employing Java/Jini te hnologies and supports experiments on luster ar hite tures via PBS and on Grid infrastru tures through Globus s hedulers. We report results of using ZENTURIO with an a tual performan e analysis and parameter study for a Globus site and a luster ar hite ture, respe tively.
