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 ?

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.

Present status and perspectivesCurrent implementation of GENIUS already includes: secure web transactions, user authentication and

authorization; Grid authentication “à la MyProxy” ! remote interaction with the user’s and “grid” file system; interfaces for job submission/control, data

management, VO servers, and to monitoring systems; Several Resource Brokers available; persistent (user’s) book-keeping and spooler system; secure interactive analysis with TightVNC ! CVS available !

Todo: web-guided creation of a job (soon !). multi-jobs (parallel and sequential); more application-specific customizations;
