ILD MDI/Integration issues 10 Akiya Miyamoto, KEK FJPPL Workshop, May 2009, Tsukuba Development of ILD technical design is the major task of coming years. Issues includes  Design of coil, cryostat, and structure  Push-pull scenario  Detector integration and maintenance LLR and KEK members are heavily involved in MDI and Integration of ILD. The issues will be studied in this program

GRID Two Vos have been used:  CALICE-VO: Test beam data analysis and MC. Standard data processing in GRID  ILC-VO: Needs huge CPU resources for the studies. Available only on GRID Standard MC samples ( ~ 50TB) are on GRID for sharing Status:  A typical data transfer rate from IN2P3/DESY to KEK: ~ 200kB/sec/port a frequent time for transfer of ~ 2GB: Cured by removing a time out at IN2P3  Overhead of catalog access ILD DST: many small size DSTs, limited by CPU time for a MC job. MC and DST production at DESY/IN2P3  Merge DSTs to create a large size file, then replicated to KEK 11 Akiya Miyamoto, KEK FJPPL Workshop, May 2009, Tsukuba
