Overview GENIUS Portal: architecture and relationships with EDG Middleware EnginFrame as a multi-purpose framework for computational and data grids The EDG services in the GENIUS Portal File Services Job Submission Services Interactive Services Other Services shown in other presentations Summary and perspectives The main points touched by this lecture: - What is the definition of GRID computing ? - How can we define a GRID testbed? - Which are the main reasons for us to use GRIDS ? We will see how GRIDs address most of the challanging issues we are currently faced to if we want to carry frontieer Research activities in many different scientific domains. - How is the European Data Grid structured, organized ? Which are its goals ? This are the questions we will be answering.

EDG M/W: around the web portal idea
EDG software (Globus, UI, JDL, WP2, WP3, etc.) contains tens of commands/switches which also have their own logical sequences. 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 for un- experienced user 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.

A little bit of history 1998-1999 2000-2001 2002-now
graphic interface to LSF (multi) clusters for ALICE jobs simple but effective web portal to submit ALICE jobs to the grid using EnginFrame and GLOBUS 2002-now official grant of the INFN Grid Project to collaborate with NICE srl to integrate in a web portal all services offered by the DataGrid middle-ware; adoption/contributions by other experiments

High level Grid middleware
EDG Globus-based middleware architecture Current EDG architectural functional blocks: Basic Services (authentication, authorization, Replica Catalog , secure file transfer, Info Providers) rely on Globus 2.0 Higher level EDG middleware (developed within EDG) Applications (HEP,BIO,EO) Specific application layer ALICE ATLAS CMS LHCb Other apps VOs common application layer LHC Other apps Grid middleware High level Grid middleware GLOBUS 2.0 Basic Services OS & Net services

Enginframe in brief Standards-based GRID portal framework
Java, Tomcat/JServ, Apache, XML/XSL → GridML Solves back-end integration problems Visual rendering for most Grid objects jobs, job arrays, hosts, services, databases, etc. Multiple Grid & Cluster technologies support EDG, Globus, LSF, SGE, Condor (soon) Authentication delegation (GSI,MyProxy, AFS, NIS, NT, Kerberos V, ...) Data management: UL/DL + remote (multi-) file browsing Integration with interactive apps End-user oriented focus! application integration

Service Example <ef:service id="gzip">
<ef:name>gzip sample</ef:name> <ef:option id="level" label="Compression level" type="list"> <ef:option id="9">maximum</ef:option> <ef:option id="4">medium</ef:option> <ef:option id="0">none</ef:option> </ef:option> <ef:option id=”FILE" label="File to compress" type="file"/> <ef:action id="submit" label="Submit job"> EF_SPOOLER_NAME="gzip $file” export EF_SPOOLER_NAME ${EF_ROOT}/plugins/lsf/bin/bsub -o output.txt gzip -$level \"$FILE\” <ef:result type="text/xml"/></ef:action> </ef:service>

Choosing the right layout
One very effective method is to select one existing page from your Intranet/Internet site You need to identify a page where you can figure out the space for the service navigation bar and the service content area

GENIUS: Summary and perspectives
Current implementation of GENIUS includes more than 100 services. Among them: 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 monitoring systems; several Resource Brokers and VO’s available; persistent (user level) book-keeping and spooler system; secure interactive analysis with TightVNC full support for “parallel” multi-jobs (“sequential” ones soon) web guided job description (from DATAMAT / NICE srl collaboration) CVS available ! Next future: Participation to the GGF Grid Portal Manifesto and GCE Working Group. Integration of IMS (Jabber) for real-time peer to peer collaboration within a VO
