21 21 Roberto Barbera EDG m/w has been released but… EDG software (Globus, UI, JDL, WP2, WP3, etc.) contains tens of commands/switches which also have their own logical sequences (“B” after “A”, “C” before “D” and so on). Browsing Grid VO “directories” (users, RC’s, DB’s, etc.) requires LDAP “speaking” and tomorrow could require SQL “speaking”. “User gridification” is a tough task for a “rookie”  this does not fit with the claim that “grids” are for everybody and that grid computing will be as easy as surfing the Internet ? Furthermore, all this holds for DataGrid. What will happen when other grids’ software (especially UI’s) will come up (PPDG, iVDGL, etc.) ? Will users have to learn tens of “grid dialects” ? Today “grid computing” is a rather complicated experience only possible at selected machines (UI’s)  this does not fit with the claim that one could do “grid computing” even from a PDA ? Is there any way to set-up a “user-friendly” grid ? Dipartimento di Fisica dell’Università di Catania and INFN Catania - Italy ALICE Collaboration ACAT 2002, Moscow,

22 22 Roberto Barbera A web portal: why and how ? It can be accessed from everywhere and by “everything” (desktop, laptop, PDA, WAP phone). It can keep the same user interface to several back-ends (grid “dialects”  command-line UI’s). It must be redundantly “secure” at all levels: 1) secure for web transactions, 2) secure for user credentials, 3) secure for user authentication, 4) secure at VO level. All available grid services must be incorporated in a logic way, just “one mouse click away”. Its layout must be easily understandable and user friendly.

43 43 Roberto Barbera Present status and perspectives Current implementation of GENIUS already includes: secure web transactions, user authentication and authorization; remote interaction with the user’s file system; interfaces for job submission/control, to VO servers (users’ and catalogues), and to monitoring systems; persistent (user’s) book-keeping and spooler system; interactive analysis ! rpm available ! Todo: multi-jobs (parallel and sequential); interface to data management and other grid services; more application-specific customizations; web-guided creation of a work flow system. Dipartimento di Fisica dell’Università di Catania and INFN Catania - Italy ALICE Collaboration

44 44 Roberto Barbera GENIUS vs. other grid portals It is not a toolkit. It is a complete production-ready environment which combine the concepts of “user portal” and “science portal”. No client software needs to be installed apart from the web browser. GENIUS can be accessed from everywhere. No security delegation (“à la MyProxy”) is needed. Access passwords are securely “streamed” only when needed. Interactive analysis (via VNC) and web access to personal spooling areas are possible. User file system is not limited to input and output files. EnginFrame modularity makes different customizations easy to implement. Already available for EDG m/w, GLOBUS, and LSF. Under definition for CONDOR (hungarian grids). It is compatible with the Tomcat open source java servlet container available from SUN.

45 45 Roberto Barbera Conclusions Computational grids could represent the “natural” environment for next generation high energy physics experiments, computational bio-medecine, Earth observation and many other inter-disciplinary applications. “Grid” could be the Internet “new age” where users can seamlessly and ubiquitously access not only information but also huge computing resources and mass storage systems distributed worldwide with their own applications. However, in order to turn dreams into reality, grid access must be easy and intuitive especially for the vast majority of non-expert users and this is the mandate of the GENIUS team. Live demos of GENIUS at work could be made for interested people during breaks in the reading area.
