Upgrade D0 farm

Reasons for upgrade

• RedHat 7 needed for D0 software

• New versions of – ups/upd v4_6– fbsng v1_3f+p2_1– sam

• Use of farm for MC and analysis

• Integration in farm network

MC production on farm

• Input: requests

• Request translated in mc_runjob macro

• Stages:1. mc_runjob on batch server (hoeve)

2. MC job on node

3. SAM store on file server (schuur)

ana_runjob

• Is analogous to mc_runjob

• Creates and submits analysis jobs

• Input– get_file.py with SAM project name

• Project defines files to be processed

– analysis script

Integration with grid (1)

• At present separate clusters:– D0, LHCb, Alice, DAS cluster

• hoeve and schuur in farm network

Server tasks

• hoeve– software server– farm server

• schuur– fileserver– sam node

• booder– home directory server– in backup scheme

Integration with grid (2)

• Replace fbs with pbs or condor– pbs on Alice and LHCb nodes– condor on das cluster

• Use EDG installation tool LCGF– Install d0 software with rpm

• Problem with sam (uses ups/upd)

Integration with grid (3)

• Package mcc in rpm

• Separate programs from working space

• Use cfg commands to steer mc_runjob

• Find better place for card files

• Input structure now created on node

To be decided

• Location of minimum bias files

• Location of MC output

Job status

• Job status is recorded in– fbs– /d0/mcc/curr/<job_name>– /data/mcc/curr/<job_name>

SAM servers

• On master node:– station– fss

• On master and worker nodes:– stager– bbftp
