1. IC Status – 29/4/02 Condor BS adaptor –New interface handles JDF`s (condor,fbs,condorG) Multi-process consumers. –In progress (crashes smaster on jobSubmitted()) –Some obvious stuff. Client on same File System as master – reads user JDF. User code on same FS as master. Want client FS separate from station and maybe Compute Node FS. What`s happening with RTE?

2. Submit D0 MC to EDG –Trivial to tar up mc_runjob prepared directories and run on Grid, but is it useful? UK money for EU/US re-use. Trivial because no input data. Increase D0 MC prod for free. GridPP Collab. 9/10th May. –30mins in “tutorial” style. –Point out real issues with Data Management..brokerinfo has file locations. Still there at runtime? Pmaster ensures delivery, retries/fail-overs. Optimizer involved. –Draft architecture and differences in information flow.

3. GSI in Sam –Toy client-server. Using gss-assist globus tools. mutually authenticate hosts pass user proxy, map to user. –Authorization Server. Use user proxy to transfer files, run jobs, Sam store, query Db, log resource usage. User sam owns cache areas. –Map all users to sam at all sites. –Give user restricted sam privileges. –CAS –Community Authorization Service –Database of user privileges –Use user proxy to get a CAS proxy. –CAS proxy allows all or subset of users` privileges. E.g gridftp from d0mino:/sam/cache20 to sampc:/sam/cache1. –User still mapped to local unix account and unix permissions always obeyed. Toy client-server-server model exists. –Client-station-stagerng –All in the detail.

4. Integration of the Globus Security Infrastructure with SAM Authentication/Authorization Service: using theGSIcertificate identity to identify SAM users; using sam-service proxy for data transfers GSI-enable Station,FSS, Stager andEWorker Authorization Service User Proxy Server Proxy Client User Proxy Stager/EWorker Server Proxy Station User Proxy Server Proxy GridFTPd Server Proxy Gabriele`s picture, from 8 th March
