1 D0 NIKHEF

2 March 22, Nijmegen2 Amsterdam D0 farm (SAM station hoeve, node schuur) –2 servers, 50 dual cpu nodes –Used for MC production Triviaal (SAM station triviaal) –1 server, 2 dual cpu nodes –Used for tests (D0RACE workshop)

3 March 22, Nijmegen3 mcp10 p10.15

4 March 22, Nijmegen4 Nijmegen doesburg (SAM station nijmegen) –1 server, 3 dual cpu nodes ? –(to be) used for analysis

5 March 22, Nijmegen5 SAM Central analysis hoeve triviaal nijmegen sara robot fnal robot

6 March 22, Nijmegen6

7 March 22, Nijmegen7 SAM hoeve –v3_1_17 triviaal –v4_0_0_3 nijmegen –v3_2_18 ?

8 March 22, Nijmegen8 upgrades hoeve –RH 7.2 –ups/upd –sam –fbs nodes –RH 7.2 schuur –RH 7.2

9 March 22, Nijmegen9 Integration with grid At present separate clusters: –D0, LHCb, Alice, DAS cluster hoeve and schuur in farm network Replace fbs with pbs or condor Use EDG installation tool LCGF –Install d0 software with rpm Problem with sam (uses ups/upd)

10 March 22, Nijmegen10 Present network layout hoeve schuur switch node router hefnet surfnet

11 March 22, Nijmegen11 New network layout farmrouter switch D0LHCb hefnet lambda hoeve schuur alice

12 March 22, Nijmegen12 Use of hoeve MC production Analysis of root tuples –Cache tuples on schuur –Analyze tuples on desktop or farm node Recompilation of algorithms Software development

13 March 22, Nijmegen13 Conclusions Exchange experience –SAM –D0 software We need use cases
