Status Report ILDG Middleware

• JLDG site www.jldg.org is in production
• MDC WS
• Using Exist XML database. We need to update
  with a new version.
• RC WS
• Simple WS one-to-one mapping from LFN to
  Transfer URL (http)
• We plan to replace a new FC interface.
• No SRM
• File transfer
• httpd for wget under simple access control by
  .htaccess
• gsiftp file transfer is also available. It
  checked by Interoperable testing .
• gridmap-file will be synced automatically with
  ILDG VOMS (very soon!)
• QCDArchive Lattice QCD Archive, Japan
• WS-enabled version of Server-side client
• MDC WS interface is used for MetaData Search
• No progress since the last ILDG9

JLDG Regional Grid

• JLDG Japan Lattice Data Grid
• New grid infrastructure for Lattice community in
  Japan
• File Sharing with GFarm Global File System
• http//datafarm.apgrid.org
• Provide file directory image by meta server
• Efficiency and reliability by replica cache
• ACL by group
• GSI authentication managed by VOMS
• Use NAREGI/KEK CA (international)
• Use JLDG CA (local)
• Some part of configuration data will be exported
  (published) to the ILDG by registering with
  metadata

JLDG infrastructure of QCD collaboration inside
Japan
A part of data can be exported through www.jldg.or

KEK
CCS, Tsukuba
Kanazawa university
Kyoto University
U. HIroshima
Data in each site is shared by Gfarm global
file system over the grid.

Plan Schedule

• JLDG regional Grid
• Move from prototype to production (almost
  ready!)
• Establish the flow of CA/RA operations and VO
  management for JLDG members
• Develop some middleware to publish data from JLDG
  regional grid to ILDG (by September?)
• ILDG middleware and severs
• Replace RC with FC
• Extend our QCDArchive to support multiple client
• Design and Develop client softwares
• It is a time to think how to use ILDG!
• Enroll users for both JLDG and ILDG!
