                                           GILDA t-Infrastructure
                     https://gilda.ct.infn.it
      Reasons why people should need a t-Infrastructure:
         •Introduce the Grid paradigm to new scientific
         communities
         •Provide expertise on application porting
         •Test of new releases of Grid services
         •Development on Grid (new services)
         •Test of middleware co-existence and interoperability
         •Provide support
         •Deliver training
         •Provide training materials

                                                          GILDA Tutorials
  •        Tutorial for Users

  •        Tutorial for Site Administrators

  •        Grid Schools/Tut. for App. developers

  •        Customized events

  •        Tutorial for Trainers

                                                         Some concepts …
  • The virtualization
       – GILDA uses VMWare to virtualize PCs/Grid Services
            VMWare – (http://info.vmware.com/)
       – An alternative software is: Xen – (http://www.xen.org/)
  • GILDA Virtual Services
       – Several virtual services are ready to use at:
            https://gilda.ct.infn.it/VirtualServices.html
       – The most important Virtual Service is the virtual User Interface
            https://gilda.ct.infn.it/GILDAVM/gLite-UI-VM3.0.tar.gz
  • The UI PnP (https://gilda.ct.infn.it/UIPnP.html)
       – Sometimes it is useful to install a UI on an existitng Linux distro
            No root privileges are necessary
            Easy to install and configure
  • Grid2Win (http://grid2win.gilda-forge.ct.infn.it/new/index.php)
       – Recently GILDA supports/tests a Windows porting of gLite

www.eu-eela.eu          Catania (Italy) , Joint EELA/EGEEIII Tutorial for Trainers, 30.06.2008 – 04.07.2008   4
                                               Tutorial for users …

  • Provides mostly Training on                                           Grid middleware

  • But GILDA also supports the multi-middleware co-
    existence: gLite, GTK4, UNICORE, Condor, OMII-UK
    (OURGrid, GTRS)
  • GILDA offers tools developed by supported projects
    like: Grid2Win, SecureStorage, GSAF, gLibrary/DRI
  • The aim of the tutorial is to let student APPRECIATE
    the service offered by the GRID and let him able to
    operate on it

                 We will focus on training for gLite

              Use of UIs running on virtual machines
              Use of the UI PnP on Linux Accounts
              Use of the GILDA glite-tutor and glite-tutor2 UI servers
       – A network connection with the outside Internet bandwidth of at least 8
          Mbit/s

                           Tutorial for Users: Exercises

  • Students need to make practice on
      – GILDA maintains a tarball file containing lot of exercises ready to
                                   ATTENTION!
         be used by students
               Install the tarball file exercises on ALL students
      – It’s a good practice to copyinto the $HOME directory home
         directories.
      – The tarball of exercises is available on:
         classic and simplest JDL example among exercises is under:
     The https://gilda.ct.infn.it/RPMS/GILDA-TAR-APPLICATIONs.tar.gz

                        gLite/Other/hostname.jdl
  • For each student account just execute:
 Other examples come from supported application portings made by the GILDA Team
       – wget https://gilda.ct.infn.it/RPMS/GILDA-TAR-
          Ohter examples show different gLite middleware capabilities, like:
         APPLICATIONs.tar.gz --no-check certificate
                                     MPI Jobs
       – tar xvfz GILDA-TAR-APPLICATIONs.tar.gz
                                   Use of APIs
         Use of well known software packages like: OpenFoam, Matlab, etc.

                 Tutorial for Users: Testing the UI
  • In case the students´ UI is centralized, it is a good
    practice to make stress tests on the UI in order to
    discover potential problems.

  • GILDA developed several stress tests for WMS and
                                  ATTENTION!

     To request the stress test scripts services.
    Storage and Cataloguingwe kindly invite you to send a email to
                   grid-prod mailing list: grid-prod.ct.infn.it

  • Stress tests may discover problems on resource
    overloading, network latencies, certificates, etc.

  • It’s a good practice to perform at least once a stress
    test over the UI hosting students´ accounts.

                 User tutorial: Running the tutorial
  • Every day ask students to sign a list containing at
    least:
       – Name, Surname, Institute, Country, email
  • Tutors will describe theory first
  • For practice sesssions Tutors may choice among:
       – Use of dedicated slides to explain exercises
       – Use of the GILDA Wiki Pages (recommended):
            https://grid.ct.infn.it/twiki/bin/view/GILDA/WebHome
       – During practice sessions ALL participating tutors will support
         students requesting help
  • At the end of the tutorial don’t forget to ask students to
    fill the Feedback Form! (see later)
  • At the end of the tutorial provide the Training Task
    Leader with the list of students and the feedback
    values.

  • Provides mostly Training on                                           Grid Middleware

  • GILDA actually supports the multimiddleware co-
    existence: gLite, GTK4, UNICORE, Condor, OMII-UK
    (OURGrid, GTRS)

  • The aim of this tutorials is to explain how to INSTALL
    and MAINTAIN grid sites.

                 We will focus on training for gLite

                          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
           local class room where students can bring strongly laptops
Sites withsimple network slower than 100 Mbit/s are their own discouraged to candidate
                             themselves to host grid tutorials.
       – 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 40 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 (gilda-ca@ct.infn.it)
       This list of hostnames will be used to generate GILDA HOST certificates.
                                         ATTENTION!
                   The number of users is limited to max 30 persons

Specified IP addresses in the request form will be enabled for incoming connections to
                                 both GILDA UI servers

   GILDA host certificates for tutorials normally expire after the end of the tutorial.
   Users might want to continue to use GILDA and have to follow this procedure:

                     https://gilda.ct.infn.it/sites.html

             Requested GILDA host certificates have one year of validity

                       Tutorial for S.Adm: Preparation
  • Dedicate a PC hosting a web server and make it accessible by
    students
  • Create a mirror of the INFN Grid software repository
    (instructions will follow on this)
       –   http://igrelease.forge.cnaf.infn.it/doku.php?id=doc:tips:mrepo

  • Create a directory seen by the web server and copy on it:

     – GILDA User certificates
     – The java JDK 1.5.0 RPM (Java Development Kit 5.0 Update XX)
     – The tarball of GILDA exercises
     – A directory containing all slides (sometime indico is slow or
       unreachable or just contain last minute slides not yet uploaded
       into the Agenda).
     – VM Image with BASIC installation (SL4 + pre-requisites)
