GDB meeting _at_Triumf in 2007

• Hi Kors,
• I forgot that I was supposed to contact you
  about having a GDB meeting at TRIUMF in
  association with CHEP'07. In talking to Randy
  Sobie, we thought the following would be good
• - Friday, Aug.31 GDB at TRIUMF
• - Saturday/Sunday, Sept. 1-2 LCG (Tier-2)
  meeting in Victoria
• - Sept.3-7 CHEP'07 in Victoria
• This would mean that people would have to fly in
  to Vancouver on Thursday. We can arrange for a
  bus from TRIUMF to the airport after the meeting
  on Friday so people can get to Victoria easily
  (30 minute flight). Alternately, we could have
  the bus drive everyone to Victoria via the ferry,
  which would be much more scenic. Let me know if
  this works we can work out the details later.
• Cheers, Mike Vetterli

Again and again CERN migration to SLC4

• Change to SL4 64-bits needs a new version of VDT
• Distribution still expected in October ?
• Some LXPLUS and BATCH nodes already on SL4
• SLC4 full rollout at CERN still in the autumn ?
  
• Well planned transition period
• When do the sites change over ?
• When do the experiments change over ?
• When do we stop the support for the SL3 version ?

Storage Class Implementations Task Force

• Charter to discuss the implementation of the
  storage classes as defined for SRMv2.2 for the
  sites
• People
• Artem Trunov (IN2P3) Chair
• Jan van Eldik (CERN)
• Mark van de Sanden (SARA)
• Artem Trunov (CMS and Alice, IN2P3)
• Lionel Schwarz (IN2P3)
• Graeme Stewart (Glasgow)
• Jos van Wezel (GridKa)
• Adrià Casajús (PIC)
• Eileen Berman (FNAL)
• Several phone meetings held during the summer
• First report given at the SRMv2 workshop last
  week
• http//agenda.cern.ch/fullAgenda.php?idaa063257

VOBoxes

• Class 1 (not so bad)
• Can access site's services (and work correctly)
  from a private network.
• Class 2 (very bad)
• Uses 'private' interfaces to access
  information/services at the site (i.e. not
  exposed to those beyond the site's firewall).
• Priority Eliminate Class 2 services first
• Reduce security issues with VO services inside
  site.
• Permit alternate, more flexible deployment
  scenarios.

11
Class 2 services

• Package management (ALICE)
• Needs to be simple, bare-bones implementation
  initially.
• EGEE/JRA1 has been discussed in the TCG
• No priority !?
• Erwin Laure
• SRM v2 (CMS)
• Need list functionality in SRM to ensure
  consistency between SE and central catalogs.
• srmLs now in SRMv2.2 for January 2007
• CMS already confirmed, performance to be seen
• Stefano Belforte

12
Class 1 servicesDevelopment Priorities

• Consistent Security Framework Erwin Laure
• xrootd as SE transport protocol (ALICE only) NN
• Eliminate use of shared credentians Markus
  Schultz
• SFT (Site Functional Tests) Pjotr Niczik
• Mechanism for publishing VO services Laurence
  Field
• Messaging and notification NN
• Monitoring via monalisa NN
• General VO service framework NN
• Let us come back to this at the next GDB

13
TebiBytes (240) or TeraBytes (1012)

• Difference is 12 for a PByte
• Vendors 1012 RAL 240 PIC 240 ALICE 240
• CERN buys in 1012 but accounts in 240
• Bernd differences of 10 depending on the usage
• Conclusions ??
• The experiments requirements are in 240
• The numbers in the MoU tables are also in 240 ?
• The sites buy in 1012 but add 12 when ordering 1
  PB ?
• Do the sites add another 10 for actually
  delivered space ?
• We keep talking about TBytes although we mean
  TebiBytes ?
• Just to make sure we all use the same rules and
  units

14
Actions on VOMS

• Jeff (Ronald actually) yaim changes
• KB email to experiments to push users to
  re-register. Final date for re-registration
  October 1st, testruns without LDAP until December
  31st.
• Ian Bird to check there is no dependency in the
  middleware on LDAP GridMap files
• dCache and CASTOR to tell us their ready-ness for
  VOMS (is DPM ready then?)
• Postpone this agenda point to the October GDB

15
Super Computing 2006

• SC06 is in Tampa, Florida Nov. 11-17
• http//sc06.supercomp.org/
• There is a first time EGEE booth
• CERN participates with CalTech and FNAL/SLAC
• Do we want to make a common WLCG demo ?
• RAL, FNAL, ANL, NL are close to each other
• http//sc06.supercomputing.org/pdf/eh_floorplan.pd
  f
• All booths are in one big hall this time
• An interoperability demo ?
• Any common videos RB monitor, network monitor?
• Any common flyers? Posters?
• Or are we too busy ?
