[Moabusers] maui/moab and job arrays in PBS

[Jay Srinivasan]

Hi,

Does anyone know if Maui supports scheduling of Job Arrays in PBS(Pro)?
If not Maui, does Moab support Job Arrays? The web documentation is
sparse, but a page on the ClusterResources site says that both Maui/Moab
support Job Arrays. However, when I submit a job using job arrays with
PBS and Maui, the job goes into the deferred state with the error (from
checkjob):

Holds:    Defer
Messages:  cannot start job - RM failure, rc: 15004, msg: 'Invalid request'

The PBS logs have no record of the job, while the Maui log says:

07/26 13:28:57 MRMJobStart(10318[],Msg,SC)
07/26 13:28:57 MPBSJobStart(10318[],JDVIN01,Msg,SC)
07/26 13:28:57 MPBSJobModify(10318[],Resource_List,Resource,jdvcn004)

)
07/26 13:28:57 ALERT:    job '10318[]' cannot run (deferring job for

Jobs run without using job arrays get scheduled and run just fine.

Any help will be appreciated.

Thanks,
