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 ?

DataGRID Project
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 perspectives
Current 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;

GENIUS installation and contribution
Send an email to [email protected] and/or
[email protected] to get an account on the
GENIUS CVS server;
Checkout GENIUS from its CVS server;
Ask your CA for a server certificate for the EDG UI on
which you want to install GENIUS
Send an email to [email protected] to get a
free EnginFrame license;
Install and start GENIUS as described on the
reference site https://genius.ct.infn.it;
New Virtual Organizations can easily be added to
GENIUS and developpers of new applications can
contribute to the portal code in a straightforward way;
Due to its modularity, GENIUS can also be interfaced
with new Resource Brokers or any other grid services.
