  • L-Store Functionality:
    • mkdir
    • ls
    • upload
    • download
    • command line help
    • storage fault tolerance via weaver erasure codes (upload and recovery)
  • Demonstration similar to SC06 (but on a smaller scale... 20 Gbs?) will be made at REDDnet@I2 meeting.
  • Clients will be made available (from REDDnet website) for installation by attendees at REDDnet@I2
    • for user testing and application development
    • files written to depots should be considered scratch
  • Server and Depot software will not be made available at this point.
  • Bugs: a dozen or so minor (non-data-threatening) bugs were discovered at SC06. As many of these as can be fixed will be, the rest will be fixed by "0.9" release.
  • ACCRE will work with Med Center Staff (Leibler/Proteomics) to begin the process of migrating them over to using L-Store instead of ADIC
  • NevoaExplorer interface (Hunter)
    • This interface will work with existing depots
    • Software will be demo-ed at REDDnet@I2
