Outline Introduction to the different e-Infrastructures –The t-Infrastructure The GILDA Project –CA, VOMS, Testbed,.. –How to join in GILDA –GILDA Support System –GILDA wiki –Multiple middleware coxesistence Run different tutorials with GILDA References

The t-Infrastructure Why t-Infrastructure? –e-Infrastructure for production –t-Infrastructure for training Need guaranteed response for tutorials; limit the vulnerability of production systems –use training grid –have training CA –able to change middleware to prepare participants for future releases on production system Also: –need safe resources for installation training –easy entry point for new communities

You will be informed that a new certificate is available in your browser certificate list. Very important: you HAVE TO use the same browser in all the previous steps It’s suggested now to export the certificate and store it in a safe place. The certificate exporting procedure and the extension of the file is browser dependent (*.p12 for Mozilla/Netscape/FireFox and *.pfx for Internet Explorer). Exported certificates need to be converted in PEM format (*.pem). This is the certificate format used by the gLite security services. How to get a personal certificate (4/5)

University courses using GILDA Spain Italy France

GILDA is not gLite centric –Triggered by the requirements of ICEAGE Summer Schools the GILDA Team has pioneered co- existence of several middleware on the same physical resources. A single t-Infrastructure can be reused also when teaching more than one middleware –The different middleware share physical resources as well as the authorization infrastructure Multi middleware features deployed also on other ICEAGE sites in GILDA This approach will be reused by EELA-2 Middleware co-existence in GILDA

GILDA Tutorials Tutorial for Users The different types of tutorials we can run on GILDA : Tutorial for Site Administrators Grid Schools/Tut. for Appl. developers Customized events Tutorial for Trainers

Tutorial for Users Requisites Audience Requisites: –Basic Unix/Linux commands knowledge (command line) –Basic concepts of networking (ssh, scp, etc.) Technical Requisites: –A computing room equipped with computers that can be used by students or a simple class room where students can bring their own laptops –Four possibilities to access the training infrastructure: Use of a dedicated UI server Use of UIs running on virtual machines Use of the UI PnP on Linux Accounts Use of the GILDA glite-tutor.ct.infn.it UI server –A network connection with the outside Internet bandwidth of at least 8 Mbit/s a FastEthernet (10/100 Mbit/s) and/or a Wi-Fi (IEEE802.11b/g802.11b/g at 11/54 Mbit/s) local area network –a big screen and a video-projector; –a sound system (microphone + amplifier + loud speakers) if the room is big.

Requesting tutorial for Users From GILDA web site:

Tutorial for S.Adm: Requisites Audience Requisites: –Advanced Unix/Linux commands knowledge (command line) –Unix/Linux administration knowledge –Good knowledge of networking and relative services (DNS, Firewall, etc.) Technical Requisites: –A network connection having outside Internet bandwidth of at least 8 Mbit/s –a FastEth. (10/100 Mbit/s) and/or a WiFi (IEEE802.11b/g - 11/54 Mbit/s) LAN –A computing room equipped with desktops that can be used by students or a simple class room where students can bring their own laptops –At least one machine (either real or virtual, with Xen or VMware) each 2 users. Machines must have direct and inverse resolution, so either : - Machines with public IP, direct/reverse solved by public DNS (or) - Machines with private IP solved by a local DNS ("pointed" by students) –Real machines should have at least 1 GB of memory per processor (dual processor machines are preferred) and at least 80 GByte of internal hard-disk –The machines must be at the disposal of tutors at least 1 week before the tutorial –A big screen and a video-projector (a 2nd video-projector for the machine to install would be better); –A sound system (microphone + amplifier + loud speakers) if the room is big.

Tutorial for S.Adm: Request The requesting procedure is the same as for users … A further step is necessary after the form submission. It is necessary to send a list of hostnames to the: GILDA-CA mailing list This list of hostnames will be used to generate GILDA HOST certificates.

Grid Schools: Requiriments Audience Requisites: –Researchers having User tutorial requisites –The Application responsible must participate to the Grid School Technical Requisites: –A network connection having outside Internet bandwidth of at least 8 Mbit/s –a FastEth. (10/100 Mbit/s) and/or a WiFi (IEEE802.11b/g - 11/54 Mbit/s) LAN –A computing room equipped with desktops that can be used by students or a simple class room where students can bring their own laptops –At least 10 real or virtual (with Xen or VMware) machines. These machines must have public IP addresses and must be registered on a local DNS with direct and inverse name resolution. –Real machines should have at least 1 GB main memory per processor (dual processor machines are preferred) and at least 80 GByte of internal hard-disk –The machines must be installed by tutors at least 1 week before the tutorial –A big screen and a video-projector (a 2nd video-projector for the machine to install would be better); –A sound system (microphone + amplifier + loud speakers) if the room is big. –Appropriate Surveillance, Fire extinguishing systems, Cooling fans and Electricity power must be granted during the school

Applications Survey There is a standardized way to organize a Grid School, like tutorials for users and site admin tutorials Normally Grid Schools are planned at the beginning of a project due to their huge request of resources Planning are normally done on TB Meetings or during Workshops. In order to collect applications a survey must be submitted to the community ( ) The list of potential applications must be provided to the TB in order to be evaluated ATTENTION! The number of application is limited to max 15 The number of days shouldn’t be less than 10 (working days) Applications will be installed on GILDA or other infrastructure (e. g. EUASIAGRID)

Summary and conclusions GILDA is a real virtual laboratory for dissemination of grid computing: –It is a “de facto” standard t-Infrastructure adopted both by EGEE and some EU-FP6/FP7 projects (EELA, EUCHINAGRID, EUINDIAGRID, EUMEDGRID, ICEAGE, EUASIAGRID, … ) –It is a complete suite of grid elements (test-bed, CA, VO, monitoring systems, web portals, virtual services, user interface plug&play) and applications fully dedicated to dissemination purposes and pre-porting of new applications to EGEE Infrastructure –GILDA runs the latest production version of the gLite middleware (and also some pre-production ones) to make the transition from the t-Infrastructure to the e-Infrastructure easy and transparent –Everybody working in training is welcome to use GILDA but, more importantly, to contribute to it in all possible ways
