There are two machines/locations involved in the installation. The hub as HUB and the cluster controller as CLUSTER.
Through this installation the $HOME directory on CLUSTER will refer to the home directory of the user that will be used to submit the jobs to the cluster (for most purposes would be any user other than root).
INSTALLATION
HUB
apt-get install hubzero-app-submit
apt-get install hubzero-submit-server
apt-get install hubzero-submit-distributor
MOVING FILES AROUND
Files can be easily transfered between HUB and CLUSTER using the scp command.
HUB
cd to the submit directory (/opt/submit by default) and add the public key found in ssh/submit_rsa.pem to the authorized keys file on CLUSTER $HOME/.ssh/authorized_keys.
CLUSTER:
Create directories submit, log, bin and scratch.
$ mkdir -p $HOME/submit/log
$ mkdir -p $HOME/bin
$ mkdir -p $HOME/scratch
HUB:
Copy the scripts needed for the Batch System that is going to be used from BatchMonitors/<YOUR BATCH SYSTEM> directory to CLUSTER $HOME/submit
Copy file LogMessage.py to CLUSTER $HOME/submit
Copy files from the Scripts/<YOUR BATCH SYSTEM> directory to CLUSTER $HOME/bin
In case it exists, remove file /etc/submit/config
CLUSTER:
Make sure the files in $HOME/bin are executable, this can simply be done using:
$ chmod +x $HOME/bin/*
HUB:
Check the ownership of the file monitorJobDB, it should belong to gridman and group gridman.
To change it simply # chown gridman.gridman monitorJobDB
Use visudo to give permissions over the bin/update_known_hosts file adding this entry:
ALL ALL=NOPASSWD:/opt/submit/bin/update-known-hosts
- The path should be changed in case that the installation was made on a different directory.
FILL IN CONFIGURATION FILES
HUB:
Add information to sites.dat
[venue_name]
venues = <comma separated list of venues>
remoteBatchSystem = <PBS or CONDOR or...>
remotePpn = <Has to be specified, if unknown set to 1>
checkProbeResult = false
remoteScratchDirectory = <path on CLUSTER $HOME/scratch>
siteMonitorDesignator = monitor_name
venueMechanism = <ssh or local>
remoteUser = <username on the CLUSTER>
Add information to monitors.dat
[monitor_name]
venue = <venue_name>
remoteUser = <username on the CLUSTER>
venueMechanism = <ssh or local>
remoteMonitorCommand = <path on CLUSTER $HOME/submit/MONITOR-SCRIPT>
- Where
MONITOR-SCRIPT should be changed to match the script according to your Batch System.
EDIT FILES
HUB:
Edit file /etc/hubzero/maxwell.conf and add the lines following lines (3) before the hub information.
visualization_params="""
submit_target tcp://<SUBMIT_SERVER_LOCATION>:830
"""
CLUSTER:
Edit the monitor file on $HOME/submit/MONITOR-SCRIPT to set this variables.
SITEDESIGNATOR = monitor_name #Same as HUB monitors.dat
MONITORROOT = <Adjust path to $HOME/submit>
MONITORLOGLOCATION = <Adjust path to $HOME/submit/log>
If you are using CONDOR and the executables are already in the user PATH set this:
CONDOR_ROOT = ""
CONDOR_CONFIG = ""
DONE!
HUB: Start or Restart submon and submit-server daemons.
# /etc/init.d/submit-server start
# /etc/init.d/submon start
