NAME ^

BatchSystem::SBS - a Simple Batch System

DESCRIPTION ^

A light, file based batch system.

SYNOPSIS ^

a short example

#edit examples/sbsconfig-examples-1.xml to put your own local machines (it can be a good idea, if you have not a cluster, to enter your local machine with different addresses (localhost, 123.156.78.90, hostname) to see sommething a bit more realistic...

#System status #in a side term, to see every second the watch -n 1 ../scripts/sbs-scheduler-print.pl --config=sbsconfig-examples-1.xml

#to submit or dozen or so scripts on queue 'single'

../scripts/sbs-batch-submit.pl --config=sbsconfig-examples-1.xml --queue=single --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh

#and on a higher priority queue

../scripts/sbs-batch-submit.pl --config=sbsconfig-examples-1.xml --queue=single_high --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh --command=a.sh

#to update

../scripts/sbs-scheduler-update.pl --config=sbsconfig-examples-1.xml

#to check data consistency (and solve main problems

../scripts/sbs-scheduler-check.pl

#to remove a job --config=sbsconfig-examples-1.xml

../scripts/sbs-batch-remove --config=sbsconfig-examples-1.xml yourjobid

submiting command

You can submit either comman or scripts.

Script submited on a resource of type 'machine' will be sshed on the host

Once a resource is attributed to a job, the script is transformed, changing the following varaibles (see examples/*.sh)

$(machinefile} (for cluster type resource)
${nbmachines} (for cluster type resource)
${host} (for machine type resource)
${jobid}

At submition time, a directory with the job number (incremented integer) is created, where stdout/err will be written.

There will also have a batch.properties file (pids, start time etc. etc.)
