NA4 Activity Goals and Organisation User Community Support & Expansion Ensure that Grid technology and the EGEE infrastructure are used successfully by a broad spectrum of scientific collaborations. Motivation: General user and virtual organization support. Work directly with strategic disciplines. Build new and strengthen existing user communities. Strategic Discipline Clusters High Energy Physics Life Sciences Earth Science Grid Observatory Computational Chemistry Astronomy & Astrophysics Fusion Support Virtual Organization Support Application Porting Support Direct User Support NA4 Management Activity Coordination Regional Participation NA4 activity has been an integral part of EGEE since its first phase. The focus of the activity has always been the end user communities and their support in high level (application porting, resource exploitation, VO creation and resource allocation etc). In EGEE-III the focus of the activity has slightly shifted from being the activity of user communities to being the activity providing services for the user communities. This is reflected in the overall structure of the activity, the formulization of Scientific Clusters and the introduction of three specialized support teams: APS, VO and Direct User Support. Purpose of NA4: To have happy users  Προχωρημένα Θέματα σε Τεχνολογίες Πλέγματος 23 – 24 February 2009 3 3

Support Teams Direct User Support Support unit of GGUS system. Focus on documentation development, use cases and documentation improvement. VO Support Provided through the VO Managers’ Group Registration, Treatment of VO issues Application Porting Support (http://www.lpds.sztaki.hu/gasuc/) Provides assistance for new and experienced grid users who wish to port applications to the EGEE grid.  Members of the team work closely with application owners to identify suitable approaches and tools for the porting process. Regional NA4 Teams (https://twiki.cern.ch/twiki/bin/view/EGEE/RegionalSupport) One team per EGEE region (total 10 teams) Responsible for first level support and signposting Ensure daily interactions with grid are effective.

HG-Site-wide & VO-SEE SW The available site-wide and VO-SEE SW is: How to find where the SW is installed: [mhaggel@ui01:~]$ lcg-info --vo see --list-ce --query 'Tag=VO-see-octave*‘ How to submit a job to the appropriate site: requirements=Member("VO-see-octave-2.1.73",other.GlueHostApplicationSoftwareRunTimeEnvironment); How to use the SW: export PATH="$VO_SEE_SW_DIR/octave-2.1.73/bin:$PATH" (this is going to be changed in the near future. It will be something like `source $VO_SEE_SW_DIR/octave-2.1.73/env.sh` but you will be informed about this change) New requests for GNU SW, at: application-support@hellasgrid.gr MPICH-1.2.7p1 VO-see-octave-2.1.73 MPICH2-1.0.4 VO-see-sunjdk1.6.0_04 MPI-START VO-see-NS2 HYDRA-CLIENT VO-see-MEEP GFORTRAN-4.1 VO-see-gsl-1.9 MATLAB VO-see-RNAHybrid-2.1 VO-see-Espresso (testing period) VO-see-FLUKA (testing period) Προχωρημένα Θέματα σε Τεχνολογίες Πλέγματος 23 – 24 February 2009

HellasGrid - MATLAB Status Trials Independent usage More info We are in close collaboration with Mathworks to integrate their MATLAB Distributed Computing Toolkit with gLite and EGEE's grid infrastructure. Trials Trial Period - limited lifespan (3-6 months). The server side has been installed in one of HG clusters (HG-03-AUTH) [mhaggel@ui01:~]$ lcg-info --vo see --list-ce --query 'Tag=*MATLAB*' CE: ce01.afroditi.hellasgrid.gr:2119/jobmanager-pbs-see Or in your jdl file include requirements = Member("MATLAB_R2008B",other.GlueHostApplicationSoftwareRunTimeEnvironment); Mathworks will propose a licensing scheme specific for the grid For the time being the trials are still on-going at least till March NOTE: the users should have free limited-time licenses in order to participate in the trials Independent usage Many users are using pre-compiled m files so they don't have to have MATLAB installed in the clusters Of course they use they own licenses for the software More info At: https://twiki.cern.ch/twiki/bin/view/EGEE/GLiteAndMATLABToolkitIntegration Contact person for MATLAB policy/licensing issues: Vangelis Floros <efloros@grnet.gr> Προχωρημένα Θέματα σε Τεχνολογίες Πλέγματος 23 – 24 February 2009

export LD_LIBRARY_PATH=`pwd`/libs:$LD_LIBRARY_PATH Some Technical Tips Make a full static compilation of your SW Get your “special” libraries with you and use them at run-time For example: put the “special” lib in the `pwd`/libs directory on the WN you are running and add the `pwd`/libs to the LD_LIBRARY_PATH export LD_LIBRARY_PATH=`pwd`/libs:$LD_LIBRARY_PATH Use the Storage elements instead of InputSandbox and/or OutputSandbox especially if you want to transfer files >10MB (in theory this limit is at 100MB) A typical scenario (it is assumed that you have created a tarball of your “special” libraries named libs.tar): At the UI Copy the libs.tar to a storage element Pass the LFN to the .sh script that it will be executed on the target WN Submit the job At the WN Copy the libs.tar from the strorage element to the current directory Untar Run the exe Copy the results (results.tar) to a storage element Echo the second LFN Copy the results.tar from the storage elements to you current directory. Afterwards delete the results.tar from the storage element Contact us <application-support@hellasgrid.gr> Προχωρημένα Θέματα σε Τεχνολογίες Πλέγματος 23 – 24 February 2009

RPMdb schema for the VO-SEE SW (1) It is based on the CMSSW installation/management procedure. A bootstrap script is used for the initial setup of the SEE RPMdb. The bootstrap script is modified based on SEE VO needs. An APT repository is available for the SEE SW rpms. A typical procedure is: The sgmsee user submits a job that will download and execute the bootstrap script on the target site. #!/bin/bash if test -d $VO_SEE_SW_DIR then wget http://repo.marie.hellasgrid.gr/see/Software/download/see/Bootstrap/see_bootstrap-slc4_ia32_gcc345.sh export SCRAM_ARCH=slc4_ia32_gcc345 sh -x ./see_bootstrap-$SCRAM_ARCH.sh setup -path $VO_SEE_SW_DIR source $VO_SEE_SW_DIR/slc4_ia32_gcc345/external/apt/0.5.15lorg3.2-CMS3/etc/profile.d/init.sh apt-get update fi After the initial setup, the SEE rpmdb should look like the example below: [sgmsee001@wn05.marie.hellasgrid.gr ~]$ rpm -qa external+gcc+3.4.5-CMS3-1-1024 external+apt+0.5.15lorg3.2-CMS3-1-1067 …………………..

RPMdb schema for the VO-SEE SW (2) The sgmsee user submits a new job for the installation of a specific SEE SW available at the SEE APT repository. The installation script could be as easy as the example provided below. #!/bin/bash PKGNAME=$1 export SCRAM_ARCH=slc4_ia32_gcc345 source $VO_SEE_SW_DIR/slc4_ia32_gcc345/external/apt/0.5.15lorg3.2-CMS3/etc/profile.d/init.sh apt-get clean apt-get update apt-get install $PKGNAME The new view of the SEE rpmdb should contain the newly installed rpm: [sgmsee001@wn05.marie.hellasgrid.gr ~]$ rpm –qa | grep see see+base-env-0.0.1-1 Of course, after the SEE SW installation is made, the corresponding VO-see Tag is added. The SEE RPMdb prototype it is already deployed in two sites, the GR-06-IASA (32bit WNs) and the HG-05-FORTH (64bit WNs). It is tested and the results are more than encouraging.

Transition to EGI/NGI model The EGI/NGI model will establish a sustainable European grid infrastructure User/scientific communities requirements: Ported applications should not be deprecated. Middleware evolution. No discontinuation of infrastructure operations No loss of centralized services: documentation, training, application porting support. EGI/NGI should also target sustainable user communities and collaborations. Προχωρημένα Θέματα σε Τεχνολογίες Πλέγματος 23 – 24 February 2009 25
