2. Presentation “a quatre mains” NIKHEF, Wetenschappelijke Jaarvergadering, 19 December 2002 EDG and the testbedKors Job submission (slides)Jeff Job submission (hands on)David 100 Atlas jobs on the GridStan …… and all this in 20’

3. The Project status  at 2/3 of its lifetime  second EU review February 4 and 5 2003  writing started on a follow-up project in the 6 th FP for 2005  LHC has accepted grid technology for its computing challenge: LCG  EDG software release 1.4 on the testbed  on the testbed: CERN, CNAF, CCIn2P3, NIKHEF, RAL prime sites  currently stress tested by Atlas and CMS with their prod.programs  others, D0, Earth Observ, biologists, etc. are testing as well  EDG tutorials given everywhere, last week at NIKHEF

4. What we will show you  the layout of the testbed  how to submit a job on the Grid  what modules/services are involved in job submission  how to get/look at the output of your job  how to deal with in- and output- files  Security is very important, but will not be shown  We assume Authentication and Authorisation are done  Once authorised a user can access all resources on the grid  Authentication: once a year, Authorisation: once per session

5. Current EDG Testbed CERN Lyon RAL ManchesterNIKHEF Reference site CERN Testbed1 EDG sites NorduGrid 21 sites 8 sites are in Europe About 340 machines are available. Some of them are dual processor. Some machines are only used for EDG. They are split into: - Production - Development NorduGrid is as a Grid infrastructure in the Nordic countries CNAF Tutorial and Core site
