Imperial Condor Log

Plain condor with GPU node as WN

• Install plain condor on cetest03 and lt2gpu00

wget https://research.cs.wisc.edu/htcondor/yum/repo.d/htcondor-stable-rhel6.repo
rpm --import http://research.cs.wisc.edu/htcondor/yum/RPM-GPG-KEY-HTCondor
yum install condor

• Open the relevant ports on both machines (wiki not secret enough to list here, I think)
• Make some users (same uid/gid on both machines).
  (Because I am no good at remembering options, here's two samples:)

   useradd -m -d /srv/localstage/user004 user004
   useradd -m -d /srv/localstage/user002 -g user002 -u 502 user002  

• All configurations go in /etc/condor/condor_config.local.
  We'll try and keep the configurations as identical on both nodes as possible, even if not every option is needed by every node.
• After changing the configuration condor needs to be restarted to reload the config file:

  service condor restart 

• This basic config files works:

  CONDOR_HOST = cetest03.grid.hep.ph.ic.ac.uk
   DAEMON_LIST = COLLECTOR, MASTER, NEGOTIATOR, SCHEDD
   SEC_PASSWORD_FILE = /etc/condor/pool_password
   ALLOW_WRITE = *.grid.hep.ph.ic.ac.uk
   UID_DOMAIN = cetest03.grid.hep.ph.ic.ac.uk
   use feature : GPUs
   # stop the emails
   SCHEDD_RESTART_REPORT = 
  <pre>
* Too see what's going on: 
** On lt2gpu00: condor_status
** On cetest03: condor_q, condor_status -long

* The other helpful command to see what's going on: condor_config_val -dump

* submit a test job (as user001)
