Spring 2007 Agenda

Please feel free to edit your agenda items. If you want to add an agenda item, go ahead but please let Rob Armstrong know. If it seems that your item has disappeared (and we didn't discuss it) look harder, it may have been rearranged into a different slot. If it still doesn't seem to be there, someone (probably Rob) deleted it by mistake. Let Rob know.

Newcomers to the CCA Forum are strongly encouraged to present a short introduction to their research and interests as they relate to the CCA.

Moving cca-forum.org to ORNL, the Saga Continues
David Bernholdt (ORNL)

Progress is being made, albeit slowly. Upcoming activities are likely to be somewhat more disruptive to general collaboration. Briefly:

• Monday: web services will move from LBL to ORNL
  • This will require Roundup and TikiWiki to be shut down for some time
• Near future: Users will have to request accounts on the new server
  • We cannot simply transfer all accounts from LBL
• Date to be Determined: Migrate CVS/SVN repositories
  • This will require an account on the new server to continue access!

I will explain in the presentation. Links used in presentation:

• Top-level server migration wiki page
• Detailed progress and plans wiki page
• Issue tracking page
• ORNL XCAMS External Account Management web site
