Resource Manager Notes → SGE/Grid Engine
Open XDMoD supports Sun Grid Engine with the caveats listed below. SGE support includes Univa Grid Engine (pre-8.2) and the other SGE derivatives that use the same accounting log format as Sun Grid Engine.
NOTE: If you are using Univa Grid Engine 8.2+ you should use the Univa Grid Engine Shredder.
Nodes and CPUs
SGE does not report the nodes used by a given job in the accounting log.
For accurate node counts the
accounting_summary must be set to
accounting_summary is set to
TRUE it will appear
that all jobs were run on a single node.
Open XDMoD supports two different ways of specifying the number of CPUs
used by a job. By default, the number of
slots reported by SGE will be
used as the number of CPUs. If you configure
num_procs as a consumable
resource, the greater of the two values will be used as the number of
If your logs are not rotated (you re-shred the same log file every time
you update the Open XDMoD database), when Open XDMoD inserts duplicate
data, the unique key constraint on the
shredded_job_sge table will
prevent the insertion of this data, but will instead update the primary
key. This will prevent duplicate data from being entered into the
database, even though the entire log file will still be parsed.
