DataTAG-WP4 meeting

8 October 2002

CMS report from FNAL demo week

Marco Verlato (INFN-Padova)

ivdgl datatag demo week at fnal
iVDGL/DataTAG Demo Week at FNAL

Demos:

IST2002 4-6 November, Copenhagen

SC2002 16-22 November, Baltimore

Goals:

  • Basic collaboration between European and US grid projects
  • Interoperability between grid domains for applications submitted by users from different virtual organizations
  • Controlled use of shared resources subject to agreed policy
  • Integrated use of heterogeneous resources from iVDGL and EDG testbed domains

from us to eu testbed
From US to EU testbed
  • DOESG certificates should be adopted by MOP master
  • CMS software DAR installation needed on SE close to CE (and NFS mounted)
  • MOP worker site configuration file to be sent to MOP master:

(1-1) Stage-in/out jobmanger grid015.pd.infn.it/jobmanager-fork (SE) or

grid011.pd.infn.it/jobmanager-lsf-datatag (CE)

(1-2) GLOBUS_LOCATION=/opt/globus

(1-3) Shared directory for mop files: /shared/cms/MOP (on SE and NFS exported to CE)

(2-1) Run jobmanager: grid011.pd.infn.it/jobmanager-lsf-datatag

(2-2) location of CMS DAR installation: /shared/cms/MOP/DAR,

(3-1) GDMP install directory = /opt/edg

(3-2) GDMP flat file directory = /shared/cms

(3-3) GDMP Objectivity file directory (not needed for CMSIM production)

(4-1) GDMP job manager: grid015.pd.infn.it/jobmanager-fork

from eu to us testbed
From EU to US testbed
  • VDT server acts as CE and SE in the same time
  • VDT client installation required on batch worker nodes (WN’s)
  • EDG certificates accepted by VDT servers (CE’s/SE’s) and clients (WN’s)
  • CMS software EDG-1.2 rpm’s installed on VDT clients (WN’s)
  • EDG Information Providers need to be installed on VDT server to be seen from RB
  • Some additional data management EDG-1.2 tools, not included in VDT server/client packages, need to be installed to be able to use IMPALA_EDG as we do in EDT-CMS testbed:
    • edg-compiler, classads, edg-replica-manager, BrokerInfo rpm’s
    • some missing libglobus*dbg shared libraries
  • Some modifications required to IMPALA_EDG to match with WN’s below private network and ldapsearch versions
first results
First results
  • Successful MOP submission from FNAL to EDG-CE/SE at PD (some minor problems for gdmp publication job)
  • Successful IMPALA_EDG submission from EDG-UI at PD to VDT server at UFL (direct submission, no RB matchmaking) with output files registered to CMS Replica Catalogue
  • CMS+EDG sw pacman-ized for US sites and rpm-ized for EU sites
  • WEB pages set up with instructions and links to packages for preparing a site for demos
  • Fruitful collaboration with CMS-US contacts (Anzar A. and Jorge R.)
  • Daily phone meetings scheduled for keeping updated and plan further steps
next steps
Next steps
  • Register VDT machines to II just set up for the demo
  • Testing pacman and rpm cache installations
  • Testing submission from EU to US+EU testbeds fully exploitingEDG-RB matchmaking capabilities
  • Testing interoperability among different VO’s (submitting ATLAS jobs to CMS testbed and vice versa)
  • Add more EU and US sites to demo testbed
  • Finalize CMS-GENIUS interface to IMPALA_EDG:
    • Work going in parallel with IMPALA_EDG refinements
    • Implementing job tracking visualization through BOSS queries
