Agenda for today's call

• Demo for AmericaView/USGS (Washington, DC; March 6-7; Terry and PR atteding) : Software and operational issues
  • Status of the GloViz client adapted for L-Store; USGS interest (PR)
  • NullPointerException on download. Download seems to complete successfully, anyway. (May be fixed by Friday.)
  • Performance: 150Mb/sec upload (1G file, 10Meg Block size, 16 Threads) 70Mb/sec download (1G file, 10Meg Blocksize, 16 Threads) In practice, this translates to 1:30 minute download time using L-Store vs 2:00 minute download using conventional file transfer. Needs to be much faster for the demo! What can we do to improve performance?
  • Can-we/How-to specify depots using the L-Store API.
  • How much space can we consume for the USGS demo (March 6th). Where should we put data? (see question 3.)
  • -1 (indefinite)keep-alive flag doesn’t seem to work – causes allocation to fail.
  • Update on status of LoRSview integration with L-Store -- Is it looking plausible or shall we start working on plan B?
• Preparation for the OSG All Hands meeting - San Diego; March 5-8; Paul, Dan, Bobby, and Kevin attending
  • Interaction/cooperation between Ultralight and Phoebus -- What are the options and oppportunities? (Martin)
  • Demo of L-Root?
  • L-Store and SRM? dCache?

Other Potential Agenda Items

Application Groups

• Geospatial
• CryoElectron Microscopy
• CMS Particle Physics
• Astrophysics

Deployment and Operations

• The most recent deployment schedule for REDDnet and L-Store software.
  • Is there any update on this schedule? A timeline of what will be deployed where and when?
  • There are demos planned for the beginning of March (AV meeting in Washington at least, maybe OSG meeting in SD as well).
• Discussion of alternative strategy for investment in REDDnet deployment - The general idea is to buy more, but perhaps less well provisioned nodes, and try to deploy them to more places where application groups will fully populate the rack with storage. (Terry)

Technology: Hardware, Software

• Review of current L-Store release schedule(Alan)
• Status of the work on Phoebus (Martin)
• Nevoa's driver level client: Shows up as another storage device under "My Computer" and speaks both L-Store and WebDav (Hunter)

Events, Education, Outreach

• List of upcoming events this Spring that we know about or that we're planning for. More details about what's planned are on the "at work" page
  • CMS Week -- February 26 - March 2, 2007 at CERN. -- Is anyone we know going to this?
  • OSG Consortium Meeting
  • AmericaView Annual Winter Meeting-- March 5&6, Downtown Washington DC and at USGS Headquarters.
  • Internet2 Spring Meeting, Apr23-25, Crystal City Marriott, Arlington, VA
    • We have submitted proposals for a regular track session and a side meeting.
    • Expectation is that we'll be accepted for both.
    • Some of our Czech collaborators (e.g. Lukas) are planning to attend.

Action Items from December call

• Terry will get the LN wiki up and going (http://www.logisticalnetworking.org)
• Alan will share the rough spec he's going to develop for libxio before he implements
• Micah will recover and put on line the old IBP spec or, if that can't be located, do what he can to replace it.
