The following is our planned schedule of releases, along with the planned features of each release and a listing of important associated activity.
L-Store Release 0.8 --- December 4 REDDnet@I2 meeting
This release is "released." Documentation and Client software is available.
- API documentation will be provided
- with the caveat that it is subject to change
- may change due to input from REDDnet community
- 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
- Full integration with L-Store will likely not be complete at this stage
