Present statusCurrent implementation of GENIUS includes more than 100 services. Among them: grid authentication with MyProxy ! several Resource Brokers, VO’s and RLS available; full support for “interactive” and “parallel” multi-jobs web guided job description, submission and

monitoring (in collaboration with DATAMAT) P2P services added PDA version available (runs also on last generation

cellular phones, e.g. Sony Ericsson P800 and Nokia 3650)

Transparently compliant with EDG2b, LCG1/2 and Grid.it middlewares/VO’s

Interfaced to many generic applications and to the CMS and BaBar grid environments

GENIUS and AliEn


GENIUS has been targeted as the grid portal for EGEE NA2 (dissemination/tutorials) and NA4 (generic applications) activities:Graphic creation/publication of new services Integration of VOMS/VOX and DGAS tools for AAACustomized version for the GILDA dissemination

test-bed (http://gilda.ct.infn.it) Integration with GAT from GridLab (in the context of

EGEE NA4/NA5) for graphic description of DAGsClose look at the technology of portlets as

containers of grid services (see how to match them with GENIUS services)

GENIUS and GAT

Q: I want to use GENIUS. Do I have to pay for it ?A: No. GENIUS is “open source” and the underlying portal framework EnginFrame is freefree for education and research communities.Q: I want to use GENIUS. Do I need any software running on my laptop ?A: No client software needs to be installed apart from the web browser. GENIUS can really be accessed from everywhere.Q: Do I have to be afraid about cached password sent over the web ?A: Access passwords are securely “streamed” only when needed and then destroyed. Only temporary sessions are possible.Q: Can new authentication methods implemented into GENIUS ?A: Of course. Kerberos V is a good example. EnginFrame is compliant with Kerberos authentication and GENIUS with AFS.



FAQ’s…and answers (1)




FAQ’s…and answers (2)Q: I want to add a new VO to GENIUS and customize new services for that VO. How can I do that ?A: A new VO can be added to GENIUS in just minutes. New VO specific services can be added just modifying only two files: an XML file and a shell script.Q: Can I use GENIUS to interface other m/w’s ?A: Yes. Although GENIUS is currently based on the DataGrid middleware(w/ and w/o GLUE extensions), it can be very easily interfaced to others. A direct interface to the Globus Toolkit already exists and another one to Condor is in progress.Q: How can I start downloading/using GENIUS ?A: Go to the reference site https://genius.ct.infn.it, click on “GENIUS CVS available” and follow the instructions.
